Title: Unmarked Microphone bodies and parts (SYT-5, CU-49, HT-11A, GT-2B, and U47)
Post by: chunger on September 29, 2012, 05:36:28 AM
UPDATE: 
NEW: M49 type bodies now in stock
GT-2B microphone bodies back in stock
Wood boxes for GT-2B, SYT-5, HT-11A and and U47 bodies back in stock


Now shipping high-quality, unmarked donor microphones for various DIY projects.  I am importing at quantity several models of microphones that have been identified as solid platforms for modification or complete circuit and internal component replacement.  These microphones and parts kits are sourced from well-established Chinese factories that have built a reputation for reliable quality.

I aim to keep these items perpetually in stock, so that folks will be able to purchase as needed when needed.  Given the bad economy, no need to "binge buy" extra projects prematurely  ;)  Hopefully, I've ordered a happy medium quantity so things will remain in stock for a little while on the first batch. . . enough time for me to pursue some other interesting items from the motherland.  But, if something runs out, a follow-up order will be placed in an attempt to maintain a reliable supply of these bodies for DIY projects and continued development of new microphone circuits.

Prices do not include shipping or sales tax for shipments within California.

C12 Circuit Clone kit designed to fit into the Alctron HT-11A or Apex 460 donor microphones.  This pcb kit designed by Matador is a faithful reproduction of the vintage AKG C12 microphone.  The power supply pcb is also designed to fit into the stock HT-11A PSU enclosure and utilize many of the stock components including the power transformer, IEC, switches, and jacks.

PCB's $30 ea.
Electronic parts kits  $80 ea.
Custom headbaskets $31 ea.

Alctron HT-11A (c12-type) tube microphone $160 - complete microphone kit - includes:

microphone
shock mount
power supply
7 pin xlr cable
plastic case

This microphone has been popularized by aggressive pricing from various name brand companies and is an excellent modification platform for C12-type builds. 

shipping weight 11.54 lbs.  - 11 lbs. 8.5 oz.
package dimensions 17x14x6 inches

-----------------------------------------

Alctron GT-2B (short U47 type) tube microphone $170 - complete microphone kit includes:

microphone
shock mount
power supply
7 pin xlr cable
aluminum case

This microphone is also re-branded by several large brands and is an excellent modification platform with its stock circuit.  It is a short U47 type body and is an excellent donor body for ioaudio 's fine mk47 U47-based microphone kit as the PCB was designed specifically to fit a commercially available variant of this chassis.  I plan to stock 3 pin XLR inserts to fit this body as it may also be a good candidate for the FET 47 clone project by poctop. 

Note to people considering this microphone who are in Europe:  Thomann sells their house brand t.Bone SCT700 that is cut from the same tooling as Alctron GT-2B and is a cheaper option and body dimensions should be the same.  For US based people, shipping would tilt the price-point in my favor.  It is not confirmed, but I believe the finish on the GT-2B may be better than Thomann's option and the PSU provides more polar pattern options.

A limited number of these will be available without the psu's at $145 because mk47 and FET47 do not require the stock Chinese 9 pattern power supply.  I feel bad about wasting them so I will attempt to sell the psu's separately or negotiate to order some microphones in my next batch without psu and retain these in stock.

package weight 11.7 lbs.  - 11 lbs. 11 oz.
package weight - no psu 8.69 lbs. - 8 lbs. 11 oz.

package dimensions 17x13x6 inches

ShuaiYin SYT-5 (U67/87 type) microphone body kit $165 - body kit includes:

body
shock mount
3 switches (pad, treble roll-off, pattern)
high quality 35mm K67 capsule
capsule mount
7 pin xlr insert
3 pin xlr insert

$145 - kit without capsule (includes everything listed above without capsule)

This body is well suited for poctop's U67 clone pcb kit as well as his new U87 clone pcb kit.  The U67 pcb kit contains the necessary PCB to mount the 3 switches onto the microphone body, so this switch pcb is not included in the kit.  U87 and other projects will require a separate purchase of the switch pcb.  Poctop has supplied me with some stock of these boards and they can be purchased for $5.

I do not know if the oem Chinese psu will work with poctop's U67 kits.  I suspect not as poctop's kit contains a PCB for the original PSU circuit that would probably have better filtering.  I would venture to say the U67 PSU PCB is too large to fit in the oem case also.  Dan from collective cases sells an excellent PSU case here on forum that is well suited for poctop's U67 kit.

The SYT-5 body kits are not complete microphones.  They do not have psu's or any internal components except the capsule and capsule mount.  I will put you on the list for

2 SYT-5 body kits

Hi,

Thanks for your interest.  I do not know if the STY-5 has the length required to house the Gyraf G7 board.  It certainly has the diameter, but until I can get a sample in hand next to a G7 board, I do not know.  I strongly suspect that it would be big enough, but cannot confirm.

hopefully someone can chime in here with better knowledge or, as these bodies become more widespread, information will be forthcoming.

FYI, if you're inside the UK, The t.Bone sct700 from Thomann will probably be cheaper all around than the Alctron GT-2B that I am importing.  If you are not utilizing the psu, the only advantage of mine would be that it does not have markings and the finish may be nickel plate instead of painted.

I have you on the list.  Please let me know asap if you plan to go the Thomann route.  I do not know exactly what the shipping will be yet because I do not have the size and weight of the kit to calculate.  Assuming the package is 4 lbs., my shipping calculator from United States Postal Service estimates shipping at ~$54.00

Correction!  I just realized I needed to click a drop-down menu to see the first class international rate which is ~$31.00.  Thomann would still be cheaper though I presume.

I will ship by the cheapest reasonably reliable method.  USPS for me has been a bit better price-wise for international shipments generally.

Also, I've been updating the list with everyone who has emailed, pm'd or posted here.  The availability for first batch in the 1st post should be up to date.

The SYT-5 should be lighter than the other microphones because it does not have psu and road case included in the kit.  Assuming each weighs 2 pounds (which I am not sure about . . just wild guessing), USPS gives me:

$64.63 - 8 pound package
$57.91 - 6 pound package
$50.00 - 4 pound package

I will only charge actual shipping/packing costs and am open to shipping via a preferred company if different from USPS.  I will be able to supply actual package dimensions and weight when the order is ready if you wish to search for pricing online.

Just a word to encourage chunger to take in consideration the efforts that other members put into this community to make DIY resources available to us.

Just found out there is a problem related to selling somebody elses design here, it has to do with the ShuaiYin SYT-5 body. It is probably not intentional and most likely has to do with a Chinese company trying to do more business, but still... we are a community here where we learn how to work together, respect the ideas from others and follow basic ethics.

ChuckD has done a great contribution putting at reach some other sought after DIY components like the Dale M7 capsule and Neve style knobs. He has done a great contribution to the community as Chunger is doing right now with the other unmarked mic bodies that were not available yet. The idea and design goes to the first one that placed the effort to make it happen.

I have a psu from my T-Bone SCT700 (which is the GT-2B I believe) and I can safely say that the DU67 (poctop) PSU circuit with the 2 transformers and everything will not fit in there. Eric (tskguy) and I have found a suitable Hammond box available from Mouser that does the job nicely and Dan (collective cases) has a PSU box that is perfect as well (and it's machined and painted with a handle).
If someone was going to use the Chinese PSU box for a G7 circuit I believe that would work.

Just my 2 cents

For the large number of commits from Europe, please take note of the package weight and size for the GT-2B and HT-11A microphones.  If anyone is aware of a courier service that can deliver these at a reasonable rate, please let me know.  They are much heavier and bulkier than I had originally anticipated.

Hi.
I've already reserved 4 bodies but I would like to get an estimate on shipping to Sweden.
Thanks!

Emil

The SYT-5 should be lighter than the other microphones because it does not have psu and road case included in the kit.  Assuming each weighs 2 pounds (which I am not sure about . . just wild guessing), USPS gives me:

$64.63 - 8 pound package
$57.91 - 6 pound package
$50.00 - 4 pound package

I will only charge actual shipping/packing costs and am open to shipping via a preferred company if different from USPS.  I will be able to supply actual package dimensions and weight when the order is ready if you wish to search for pricing online.

Do you have any pictures of the U67 body with a capsule inside the headbasket? Curious how its height compares to that U67/87 you picture next to it.

I may want to reserve 4 U67 bodies.

This is a photo of the stock SYT-5 with the Lundahl transformer option.  Shows the K67 capsule position.  Looks to be proportionally lower than the U87.  A different capsule mount could make closer. . . a plexiglass shim could also do the same I guess.

It's been confirmed that SYT-5 body is not long enough to fit the G7 PCB.  A new PCB would have to be laid out or point to point build fir it to work.

Quick question: does the SYT-5 come with the tube mounting bracket thingy? Also, just an aside, but it may be cost effective (or maybe not or too complicated) to ship to one person in Europe, and have that person ship forward. Don't know if that would work or not.

The G7 PCB can be easily shortened (by a bit) but not narrowed (by much)

I posted earlier in the feeler thread that the absolute maximum length inside the SYT-5 body is 4.495 inches.  According to my printout, G7 is 4.740 inches long.  There is plenty of width in SYT-5, but not enough length for the PCB without modification.

Hi jandoste,

Thanks for the interest.  I will put you on the reserved list along with others who have expressed interest.  When I receive the microphones, I will contact everyone and start taking payments.  For now, I'm just tracking reservations on a list.  Microphones are scheduled to be complete at the end of the month.

Absolutely no problem in removing 0.25" from the length of theG7 PCB, so you are confirming that the width of the inner frame is at least 1.625"?
If so I defiantly want one, with the capsule mount.

The capsule mount is in the SYT-5 kit list. 
So, from what I understand (!) it's part of the package, but it can also be ordered separately.

The width of the inner frame at the narrow end is 1.815".  It widens to 1.840" at the wide end according to my dial calipers.  Note, the frame is pretty "bendy" so measurements vary along the length.  The capsule mount as well as the 35mm K67 capsule are included in the kit.  The capsule as described in the top post can be excluded from the kit to shave some cost off.  I will add you to the list for one SYT-5 body kit.  Please let me know if you want the one without capsule.

Small update:

The factory is on-schedule for end-of-October completion of the mics that have been ordered so far.  I have contacted everyone that I have on the reserved list to collect logistical information.  Please check your email and PM inboxes and respond to the information request if possible.

If I did not contact you, either you are not on the list, or I have incorrect contact information for you.  Please send email to [email protected] .

I apologize for the current shortage of GT-2B microphones.  I did not have enough time to alter the order quantity when an influx of reservations for these came in.  It seems I will have a temporary lapse in stock of these until a follow up order can be placed to replenish stock.

Once pre-reserved copies are distributed, I will list all items to my webstore and hopefully, very shortly, everything will be happily in stock and available for general on-demand purchase.  Thanks for your patience as I get this project off the ground.

(or would it just need too many upgrades to be worthwhile) ..?

The PSUs have a 6V regulator which does a good job at keeping heater voltage at 6V. There are also two zener diodes which regulate the B+ voltage. I can't recall what they are stock but I replaced the zeners in mine with lower values. It's quite a simple modification. From memory, stock B+ was somewhere between 145V and 150V.

The big issue I've had with these power supplies is polarisation voltage which when stock is somewhere around 70V and 75V. I modified the switch to divide the B+ voltage for polarisation.

As you may be aware, it seems all GT-2B's in the 1st shipment are reserved.  There are, however, a few folks on the list for GT-2B that have not responded to my follow-up attempts so there may be some attrition which would work to your favor.  I will keep you posted.  Please PM or email me with the following info:

ShuaiYin is past their revised lead time to complete my batch of bodies.  My Chinese associate is pressing them for updated information daily.  No news as of right now.  The implication is the batch is in the nickel plating stage.  I will update this thread as soon as I have any information.

I prefer to see all products with my own eyes before shipping out, but if any of the many European customers has reserved GT-2B and/or HT-11A, please let me know if you would like your orders shipped directly from China to receive microphones sooner.

Again, I apologize for the delay.  Hopefully I will have some good news soon.

I do not know if it will save shipping cost.  It will certainly save time as the packages will not have to come to me first on a boat and can ship immediately. I have actually already forwarded microphones to a few people this way who needed them ASAP.  I can run shipping estimates both ways and choose the cheapest route for people who are interested.  There are about 4 reservations that might benefit from this arrangement.

A number of B-stock microphone tubes are available now for folks who may have SYT-5 bodies with incorrect pattern switch markings for the U67 and U87 clone builds.
I'll take one!

p.s. These have cardiod in the middle, yes?

Duh oh. . . sorry dmp, I was incorrect. . . the bodies that were sent could possibly be parts for mics who's guts are packed on the cargo ship.  I will have to hold off on selling these until I see what came in the main shipment.

The factory was short a few body tubes at the time the ship left Shanghai, so these bare tubes that were shipped could be attached to microhpones in the main batch. . . not B-stock.

How Will we know if we're on for this batch or a second one?
I'm really locking forward to putting this microphone together.

I'm about 60% done invoicing everyone who reserved microphones in the order reservations were made.  It is very likely that I will have enough stock to supply all requests to date.  GT-2B microphones might run out, but there are a few people who cancelled their reservations of GT-2B microphones so everything might work out.  Everything else will be in stock at least for a while on the first batch.  I will post to this thread when everyone that I have on the list has been invoiced.  At that point, if you have not received a notice and have reserved something, you should contact me again to verify.  For now, I am invoicing as fast as possible.  Actual shipping costs are being calculated for each order.  I apologize for some of the rates that are coming up.  These packages are larger and heavier than I expected so shipping costs particularly on international orders are not as good as I had hoped.

Thanks everyone for your support.  For the people I have invoiced so far, a payment before the new year would be tremendously helpful for me at this time logistically.

Microphones are in the CBP warehouse near my house and at this point, all payments have been finalized and the cargo has cleared customs.  I will be picking up tomorrow morning and begin shipping immediately.  Some folks who ordered SYT-5 kits should have received them already due to the early arrival of a few units by air mail.  Due to the volume of pre-orders, it may take a few days for me to process through and send everything out.

At this point, paypal invoices have gone out to everyone who has reserved microphones.  If you have made a reservation and have not received an invoice, please contact me immediately.  If you would like to withdraw your reservation for whatever reason (high shipping costs, etc.) please let me know as well so I can release those microphones to another customer.

Thanks again for your support.  Now the packing begins in earnest.  More than 1/3 of the orders went out to Europe.  I'm wondering if I need to locate a staging point across the pond.

Thanks everyone who has submitted payments for reserved mics.  I am getting close to 25% shipped right now. 

For those who have not yet paid invoices that have been sent out, it would be extremely helpful for me to receive payment before the new year.  About 60% of all reserved mics are now paid and shipping soon.  Due to volume of orders, it is taking a bit of time packing and shipping, but we will get all of these out as soon as possible.

Also, if you have not received an invoice from me at this point and have reserved something, either I made a logistical error or I do not have you on the list.  Please contact me.

Thanks!

The cases are great and everything was as ordered.
Great job for putting this together.

We are now critically low on GT-2B microphone stock, so at this point, unless you contact me to hold the reservation, reserved GT-2B's that have not yet been paid may get bumped for new orders for GT-2B.

Hi,

Check in the shock-mount box (or at least that's where I put them in most packages).  In a few of the early shipments, I may have put this parts packet inside the microphone body, but the vaste majority of orders had these packed inside the shockmount box.  There should be a little baggie that contains:

1x 3 pin XLR insert
1x 7 pin XLR insert
3x 1/4" height nylon spacers
3x 12mm M2 screws (for mounting switch pcb)
1x on-off-on pattern switch
2x on-on pad, low-cut switches

If you did not get one of these baggies, I need to send one to you.  It might have been very late at night and I missed one.

This may also be off topic, but the C12 project that I am collaborating with Matador on was designed around the HT-11A body and is nearing release. . .

http://www.groupdiy.com/index.php?topic=50277.0 (http://www.groupdiy.com/index.php?topic=50277.0)

Straight ahead mod to the factory pcb's is also a very economical way to a good mic, but our kit completely re-designs the power supply with full wave rectification, better filtering, and supplies the fixed bias voltage while retaining the stock case.
Title: Re: Unmarked Donor Microphones and Associated Parts from the Motherland
Post by: tchgtr on January 10, 2013, 05:03:06 PM
    Blue Jinn,
   I'm just doing an old-fashioned DIY conversion to C12 circuit with the PCB from the mic. I've been following the Chunger/Matador C12 thread, and it looks great, but I'm goin' ol' skool for the moment, tho planning on ordering a head-basket or two.
     Using a Cinemag CM-2480, one of the group-buy RK-12 capsules and parts from local suppliers. Found a nice 6072 locally also.
    Also have a Nady 1050 that still has the CCDA in it, a good 12AT7, and improved caps. Trying for more of a 47 vibe from that so I put the stock HST-11 capsule in that, replacing the RK-12 I had in there, which sounded pretty good. The new 67-style capsule from the HST-11 sounds better than the original 1050 one did, but still honky. Guess the QC has improved over the years, but I will eventually put something a little better in there, and hope Dale keeps making the M7s until I can afford one.
    Will hopefully upgrade the HST in the future to a higher quality capsule, but will go with what I have for now.
    Will also upgrade my Big Ugly/G7 with an RK-12 (currently has the old 1050 capsule in it) and Cinemag, but have a long weekend of work ahead before I get time for that.
    Then I need to do a LOT of recording with these so I can really get a feeling for them.

Received my microphones in a perfect shape... Thank you so much !!!
The HT-11 has the top of the head basket a hurted but it isn't due to shipping or handling by you... Certainly a fall out of the box in the factory... China's way of perfection...
So :
Thank you, thank you, thank you !!!
Title: Re: Unmarked Donor Microphones and Associated Parts from the Motherland
Post by: chunger on January 12, 2013, 05:44:43 PM
Oh no!  A number of the HT-11A's had dent near the top, center of the headbasket, and I ended up opening each box and straightening all of them up before shipping.  From now on, I think I will need to pack them with an extra piece of soft foam at the headbasket before I ship.  I think the problem is widespread because the spare headbasket I bought from Dave Thomas at Advanced audio also had this problem.

Sorry about that, I hope it cleans up perfect.  I will notify the factory and see if they can do anything about it on the next shipment also.

If anyone else has this same problem with HT-11A, please let me know so I can figure out a solution.  These all shipped out in perfect shape and I need to make them arrive in perfect shape.

I am now working hard on some nice customizations for the 2nd round of shipments from China so please stay tuned.  Hopefully we'll be able to offer a better and better product at a better price as this project moves along!

For now, there have been over 600 pounds of microphones shipped out.  I hope everyone is having fun with their builds.  I know I am.

Yes.  I have loose psu's for $40.00 .   

I am planing to kit them with the PSU board that Matador designed as a complete "universal" tube mic power supply setup.  Full wave rectified. . . better filtering than stock Alctron, and supplies fixed bias voltage and heater voltage.  It can also supply 210V-120V at B+ by swapping a couple resistor values.

Hi chunger,

Excellent work!
Any timeframe for new batch of GT-2B´s?
Title: Re: Unmarked Donor Microphones and Associated Parts from the Motherland
Post by: chunger on January 24, 2013, 07:18:34 PM
The last 2 GT-2B's are a pending transaction.  If that buyer decides to back out for any reason, I'll have 2 available now.

Because most projects that utilize the GT-2B's typically don't require power supply, there is significant waste and extra cost involved with importing this microphone "complete" that I was not very happy with.  I am now working directly with a metal fabrication factory in China to make me another suitable body.  I am being careful to ensure that all currently available kits for the GT-2B platform will fit nicely in the new design and that build and finish quality will be on par or better than what we are working with now.  First round prototype for this body should be ready sometime shortly after the Chinese New Year holiday.

I am also taking the opportunity to try and adjust the mesh material to a close match of the 3 layer U47 headbasket.  I was hoping GT-2B stock would hold out until the end of the development cycle for this new body, but unfortunately, we ran out fast.  If development of the new body is looking to take too long, I will put in another order for GT-2B's, but I think we will be able to move this along quickly as we are mostly tweaking a few details on existing tooling.  We should see a better product at a better price with much better shipping cost.  In the long run, I think this will be a better platform for DIY with less material and logistical waste.  Also, I was unhappy with the stock pcb setup that solders the tube directly to the PCB as opposed to use a socket.  I think this reduces the "moddability" of the stock platform significantly.

my plan is to also import an aluminum case that will hold 2 microphones and 2 shock mounts as a purchase option.

The HT-11A seems popular in stock form and quite a few people purchasing those seem to be modding the stock microphone, so I will keep ordering those from Alctron as needed.  Because we were able to make our psu pcb fit inside the stock enclosure and re-use the power transformer, enough of the original mic is used to justify importing these complete.

I will def be on the pre-order list for one of the GT-2B mic bodies with the modified headbsket.

Lining up logistics for next microphone order right now. . . currently prototyping 2 new bodies directly with a metal factory to replace GT-2B and SYT-5 in my offerings. . . so the majority of my efforts are directed towards those details right now.  All current pcb kits will be compatible with the new bodies and quality/features on the microphones themselves should improve. 

I am planning to make aluminum cases available configured to hold 2 microphones + 2 shock mounts each.  At this time, I have not considered wooden boxes for the upcoming order, but all is possible with enough interest.

Yes, the T-Bone SCT700 is cut from the same tooling as the GT-2B I believe.  All PCB's should fit perfectly in that body.  The only difference is it uses a painted finish instead of nickel plating like the GT-2B.  Alctron's quality control on cosmetics seems to be a bit better.  Also, I'm not sure if the power supply is the same, but for most projects, people are not using the psu's from the GT-2B.

I finished a mod of the GT-2b using a k47 capsule, 6072 tube, and Beyer transformer. The mic sounds wonderful and was fairly cheap. I have a 2nd matching capsule and transformer, so I would really hope to get a 2nd gt-2b just like the first to mod. Please put me on the list if any cancels and also since the demand is so high as is, please consider a new order for Gt-2b same as before.
I put in a socket and it worked out really well. I can post some pics.

Hi Dan,

I needed to order another GT-2B in China for development reference on my new body, so I should at least have that one sample microphone in the 2nd large shipment when that happens.  I will keep you in mind.  It seemed the HT-11A was a much more common modification platform stock and most people were gutting the GT-2B and/or purchasing without the psu, so my focus is primarily on reducing cost and improving features for kit application on the short 47-style bodies.

Alternately, I and many other people probably have the "guts" from GT-2B microphones in a bin somewhere.  The stock PCB will certainly fit in the new body, so you may be able to pick up GT-2B internals cheaply from any number of people on forum myself included and insert them into the new body.

Frame dimensions, mounting hole locations, and switch pcb mounting should be the same as current version.  I am looking into a tighter headbasket mesh to track closer to the stock U87.  More information after the Chinese New Year holiday.  All the factories are closed until the 18th.

USPS just increased their prices for flat rate boxes.  The webstore shipping calculator as I have it set up currently will spit out a price that will actually make me lose money on shipping.  Shipping calculator is telling me actual shipping cost will be $77.95 to France.

Hi,

Dide

Yes.  The samples that I requested have been finished (polished nickel plate) and will be shipping to me by air in the next few days.  I requested 4 single layer C12 type samples and 2 double layer Ela M251 type samples.  I have already transferred funds for the full production run of 500 units to my associate in China, so as soon as the samples are confirmed, we are moving ahead with production.  I do not anticipate problems because the prototype has already been test fit on to the HT-11A body and the fit looks good.

One of the first things that will happen when the samples arrive is parts will be flying out to Tim Campbell for evaluation and capsule optimization.  That will be the final piece of the puzzle as far as full kits are concerned.  I have all electronic components and hardware in hand and am bagging kits right now.

Also,  is the SYT-5 headbasket project on the same schedule as this one? Any prototypes yet? Or one at a time? Not rushing you, just very interested...

Last one...  I read in a thread somewhere that you were looking at getting a box made for the SYT-5 as well.  Is that still in the cards?

As you can probably tell,  I am keen on both of these projects and will very likely be in for one of each...

Keep up the great work.   I'm a fan.

Post by: chunger on March 06, 2013, 03:12:58 AM
There are plans for the Ela M251 type project, but we are having some serious debate about whether a new pcb is needed after revisiting the pcb layout.  There are a couple of issues at play.

1.  The Ela switches polar patterns from the microphone and currently, the HT-11A body does not have provision for a switch
2.  The turret board layout of the pcb easily accommodates the required circuit changes to get very close to the Ela.

The conclusion is we can build the Ela type circuit with the only key difference being the way the capsule is polarized (retain the 9 pattern switch at the PSU).  We bypass the bias voltage section of the psu as well for the Ela build.

Essentially, we get an ELA with the more flexible patterning options of the C12.  We are at this point reasonably sure this can be done on the existing pcb layout with a few easy component changes.

I'm preparing for the ELA in whatever iteration it ends up being released in by lining up the hard-to-get parts (mainly the headbasket) now.  Right now, I'm strongly leaning towards focusing on building the ELA circuit on the current pcb.  But, the first priority is to finish out the C12 project and get all the ducks lined up on that front.  I'd like to get the capsule finalized and headbaskets in stock and shipping before turning my attention to the ELA build.

I've received more than a few inquiries about hookup wire for the C12 microphone kit.  I guess I had assumed most DIY people accumulate this sort of thing and have their own personal preferences about what types of wire they like to use are.  But, apparently, PTFE silver teflon wire is not as easy to get as I thought?  I'm going to look into buying a bit more than I need for my personal stash and making some of this available in the webstore.

Monitor the white market thread, and I will announce when I have a specific timeframe for the next large shipment from China.  All mics will be in stock at that point and I will be ordering enough to keep everything in stock for some time.

Due to quite a few inquiries, I have purchased a good amount of silver plated teflon wire to make wiring kits for the C12 kits (or whatever other microphone you intend to build with these donor bodies).  I purchased all of the colors needed to replicate the original color scheme with the addition of violet for the bias wire.  These will be 22 AWG for the bulk of the power supply and microphone internal wiring and 28 AWG for the capsule wiring.  Kits should go live in the webstore in about a week.

I have also spoken with Gotham Cables and purchased a spool of their GAC-7 cable for folks who are interested in upgrading to what some consider to be the best 7 conductor microphone wire available.

Tiny steps closer to complete kits!

Well, I did purchase yellow  ;D  If you want a 100% yellow kit for enhanced sonics, please let me know.  I'm certain as long as you are able to keep track of where all the wires go, it would sound WAYYY better than the standard multi-color kit.

Hey chunger,

Are you still planning to offer a kit that includes EVERYTHING (pcb, electronics, headbasket, transformer, and capsule)? Or maybe you never were and I misunderstood.

Just wondering if I will have to wait months on a Tim Campbell capsule straight from Tim (I think there's months of lead time), or If I should just wait for your complete turn-key package. Thanks!

I'm going to attempt to carry a full kit at some point, but I do not know when that will happen.  Piece by piece, I am getting closer, and I am making all of the individual parts available on the webstore as I gather them at volume.  So, it's up to you to decide when and how to buy.

I recommend getting on Tim's build queue for his capsule though.  There really isn't any way for him to significantly ramp up production volume, so I have to get in line just like everyone else and the lead times would be the same.  FWIW, I am waiting for his evaluation of the kit before ordering a few more capsules.  Other people have contacted Tim already to secure a slot in his queue for capsules.  There will be no cost penalty to sourcing the capsule yourself.  Actually, there will be no cost penalty for sourcing any of the parts yourself besides shipping.

At last report, the lead time is 8 weeks.  I am not in the queue because I'm waiting for confirmation of the final capsule specification.  It may likely end up being the stock configuration, but I won't know until Tim has a chance to build the kit and test.

We will likely be out of stock on all donor microphones within the next few days.  A follow up shipment from China is in process, and I have significantly increased my order quantities because I do not want to keep things in stock longer.

Because I am making design improvements on all of the donor microphone models being offered to get closer to original specs and based on design requests from poctop, there may be a longer-than-normal lead time for this 2nd batch, but there should be plenty of microphones to go around once it arrives.  Please monitor this thread for up-to-date information on progress.

At this time, the earliest I can foresee receiving the shipment is 2 months.

Shipments of C12 parts kits are incurring a slight delay.  I had been sourcing knobs for the 9 position pattern switch from an actual electronics supply store that is local to me.  In the internet age, it is nice to see an actual physical store still open near me and I like to support them whenever possible  :o.  But, apparently, I have cleaned them out on chicken knobs.  A re-supply order is en-route to me, but shipments of C12 parts kits will be delayed by a few days.

Sorry for the inconvenience.  Due to demand, I am still generally running about 1 week behind in shipping all products.  Your patience is much appreciated.  I am still trying to streamline my order fulfillment process.

Post by: micaddict on March 21, 2013, 07:11:34 AM
There are plans for the Ela M251 type project, but we are having some serious debate about whether a new pcb is needed after revisiting the pcb layout.  There are a couple of issues at play.

1.  The Ela switches polar patterns from the microphone and currently, the HT-11A body does not have provision for a switch
2.  The turret board layout of the pcb easily accommodates the required circuit changes to get very close to the Ela.

The conclusion is we can build the Ela type circuit with the only key difference being the way the capsule is polarized (retain the 9 pattern switch at the PSU).  We bypass the bias voltage section of the psu as well for the Ela build.

Essentially, we get an ELA with the more flexible patterning options of the C12.  We are at this point reasonably sure this can be done on the existing pcb layout with a few easy component changes.

I'm preparing for the ELA in whatever iteration it ends up being released in by lining up the hard-to-get parts (mainly the headbasket) now.  Right now, I'm strongly leaning towards focusing on building the ELA circuit on the current pcb.  But, the first priority is to finish out the C12 project and get all the ducks lined up on that front.  I'd like to get the capsule finalized and headbaskets in stock and shipping before turning my attention to the ELA build.

I reckon that will include Matador's attention?  :)
One of the nice things of this GroupDIY project is the collaboration.
And regarding the Ela M251, I even see a possibility for a threesome, so to speak.

The Ela M251 as described in the quote is actually the Ela M251E, with the E from Export. That one uses the 6072a tube. The European version (and this is a European microphone) used the AC701. Now we all know that that tube is very expensive and hard to come by. But the 5840, when used as a triode, is a pretty good alternative. Its use in modern M49 clones is just one example. And it is used in any more microphones. It is readily available and affordable. The 6072a, however, is not so easy to get in NOS high quality. Even if you're lucky enough to get, and willing to pay for, a GE five star, there's a good change it has been tested and rejected by others before you. Fortunately for the C12 project, the situation isn't yet hopeless. But with the 251 we have the choice between two versions, which could be used as an advantage.

So here's a plan. Make the Ela M251 in the non-E version, or at least have that as an option. That version could then be used with poctop's fine new PSU (PCB) which he designed for the D-49 and D-269. Apart from being able to feed self biased mics, it has even been made stable enough to feed filament biased ones. But that's not necessary here. It doesn't hurt to have it on board, though.

What do you say?

...it shouldn't be overlooked that there may be another 9-pin dual-triode tube that is more readily available and cost efficient than the current supply of 6072 tubes for use in a "251" type microphone...David Bock has recently implemented the 6021 (12AT7WA) into his 251 (previously used 6072 and briefly, a 5670)...granted there may be some tweaks necessary in the circuit to make the best of the higher (mu) gain rated 6201...I have been using GE 5 Star 6201 tubes in a few of my tube mics with excellent results...the swap results in slightly different voicing, but in some cases preferable over a 6072...in a couple of my tube mics, the 6201 offered a more mid-forward voicing, with less top-end push than a 6072...IMHO, ended up being the better choice for that particular mic...

...just a thought!
http://www.bockaudio.com/251.html

...as an interesting side note, David Bock sources his capsule from MBHO (Germany), who's chief engineer is a former Schoep's engineer:

Yep, I thought about that, too, and figured (hoped actually) you'd chime in, kidvybes.  :) Thanks.
But the 5840 is a great choice, as well, and it can be a new standard for more than one microphone. Sort of like the old AC701 standard for broadcast in Germany etc. And, like I said, it would be closer to the actual 251 (not the E adaption).

...definately!...David Royer's subminiature tube of choice for his tube microphones...and subminiatures like the 5840 are less likely to exhibit excessive microphonics...these were the latter examples of pentode tube evolution...

  It's a very good choice.  They are cheap, built well, less inclined toward noise issues, and similar to the original.  That gives them a huge advantage over most of your other options.  I'm in touch with a number of mic builders and several of them have reported positive things about their 5840/251 mic builds.  If you plan to offer a kit or board, let me know and I can see about offering some pre-screened and burned-in 5840s.

Hey guys,

Technical details about alternate tube implementation are quite a few levels above my pay grade. . . I'll alert Matador to this line of discussion.  I know the first iteration of the Ela M251 in our use will be the 6072A because no changes are necessary to the pcb's so we can basically build it at any time.

But, if anyone wants a pretty picture taken of something, give me a call  :o

hopefully Matador will be able to chime in soon.

Post by: micaddict on March 22, 2013, 12:28:24 PM
The 6201 as an alternative for the 6072 could be discussed further in the C12 build thread, I guess.
But I didn't want to hijack that thread with my Ela M251 ravings.
Also, my post was in reply to one of chunger's posts in this here white market thread.

I've PM-ed Matador.  :)
Title: Re: Unmarked Donor Microphones, C12 Kit, and Associated Parts from the Motherland
Post by: Matador on March 22, 2013, 04:38:48 PM
Using a 12AT7/6201 would be pretty simple with a few BOM changes.  The plate resistor would need to be dropped to about 47K, and idle current would need to increase up to about 1-1.5mA with a -1V bias.  Gain would be similar as well.  The series PSU filters (90K) might need to be lowered to keep B+ in the right range.  Input headroom would be about the same as well (about 2VPP).

A miniature pentode like a 5840 should work as well with similar tweaks.  It takes much more bias current (when wired as a triode).  It could be wired directly to the tube PCB interposer (just leaving off the 9-pin socket):  one of the reasons I provided 3 copies of the tube board on the panel. ;)

In terms of ELA 251:  I think a lot of that sound comes from the 1000pF plate cap that is not there on the C12.  I've found if you stick a cap on the plate on the existing C12 board, it tames down the high end a bit and makes it sound much more "251" like (although to be honest, the same can be done with a low-pass filter after the recording is done).

There are those that would argue that the 251 is "cathode bias" and the C12 is "fixed bias":  however that isn't true.  They are both (in reality) cathode bias.

Yes, it will work. . . not only will it work, but you may be shockingly surprised at how good it is.  My mk47 that I put into the studio with my cheap 35mm K67 capsule ended up getting used for main vocals on a big (for us) project.  I was absolutely shocked when I heard that's the mic they used.

Certainly not the traditional U47 sound, but a good sound.  I have 2 beesneez capsules coming this week, and I may have to build another mk47 because they want me to leave this mic alone at least for this artist.

Henk...I like the sound, considering it's captured "unplugged" with little to no processing (he did boost the 2 buss at 10k)...surprisingly balanced recording in figure 8, IMHO...

...as per Joe West, the producer/engineer, "I've attached a link to a video shot of Phoenix Drive, a band that I've been developing. All done live in 1 take out at my barn... Only using Advance Audio mics--> API 3124's-----> Apogee Symphony I/O. Very little processing. No individual eq or compression... Just 2 bus compression and a boost via my analog Manley Pultec up high @ 10K. So U can hear them pretty unprocessed!"

On another note I was wondering if someone could do a quick diagram of how they wired the mk47. More specifically the connection between the 7 pin connector and the microphone. I've been reading the threads and a diagram would really clear up a few things. I'm sure it would be helpful to others as well.

Haven't finalized anything yet, but here is where I am headed.  The GT-2B body will be replaced by a new body with the same internal rail configuration but properly spec'd 3 layer mesh configuration.  The DIY options for this body do not require the use of the stock power supply, so I deemed it a waste of materials and shipping costs to bring in the complete microphone kit for this body.  It is completely possible to bring in additional GT-2B type shock mounts so people can have an option.

Also, due to shipping costs particularly to non-use countries, I am bringing in padded aluminum flight cases, but they will be smaller than the full kit boxes because they will not accommodate the stock power supply which is discarded anyways.  Cases will be designed to hold just the microphone and shock mount. . . actually, 2 microphone bodies and 2 shock mounts.  Cases will be sold separately so people who prefer the cheapest possible shipping weight, size, and cost can have that option.

I am debating whether or not to order large cases that would accommodate the Dan's very nice microphone psu enclosure which is popular for DU67 and mk47 microphone builds.

The same case should fit all of the existing SYT-5 bodies that have been sold.  I have received several inquiries about that.

All of these details are being decided right now, so if you have input, please chime in.

The sound needed for our particular track required a bit more "bite" and the K67 type capsule does have a lift in the upper registers.  Note, the U67 circuit has built-in treble de-emphasis unlike the OEM based circuit used Stellar's microphones and the mk47.  So, if you are particularly treble averse, this may not be the right capsule.  This particular 35mm capsule does still exhibit some of that treble lift, but is designed and optimized for use in a flat circuit, so perhaps it is a bit tamer than a true vintage reproduction K67 capsule.

That being said, I like the mk47 microphone paired with this capsule even though it is "wrong".  Technicalities   ;D

I have a u67 using dans case for the psu, and a second in the works. You can count me in on two full cases, as long as the price isn't outrageous, of course.

...I have used these aluminum utility cases for multiple mics and accessories...they have "pick/pluck foam" as well as hard dividers, and the tool holder in the lid is removeable revealing more foam lining...easy to detail for your particular use, and relatively inexpensive (usually under $30):

http://www.harborfreight.com/18-x-12-34-x-6-aluminum-case-69318.html

i bought one of these cases for my ioaudio MK7 build and while they are o.k. the foam in it is very soft and offers little support.  i ordered slightly better pick and pluck foam from Foam Factory and will let you know how it goes.  The case also has two metal brackets which hold the drop down tool holder flap on the inside of the lid which is attached to the same "rivet" button which holds the lid latch.  when i tried to remove the two brackets it weakened the latch a bit.  will need to replace the rivet in the future.

p.s. Chunger i emailed you but thought i'd post here too.  i would like to buy a couple of dany's switch pcbs for the SYT-5 bodies but did not see it in the store. do you still carry them?  thanks!

Per requests here, I am changing specs on the new bodies. . . the GT-2B and SYT-5 use a M26 thread base for the bottom cap as well as shockmount.  The new factory I'm dealing with standardizes on M24 for the bottom of their mics.  I'm working on getting specs for my mics changed to M26 to be backwards compatible and use a single threaded shock mount.  Depending on how difficult the change will be, I may end up still going to the smaller M24 threaded base.

Shifts like this eat into development time, but I'd rather get all the details right the first time around even if it will be a bit longer lead time for the 1st production run.

My factory contact informs me that we are close to having prototypes to verify compatibility with all existing kits.

No, modifications to the design are being finalized and I will need to confirm all kits are compatible with the body before production run can begin.  This will take some time.  I was hoping stock of SYT-5 bodies would hold out longer to allow for continuous supply during this development cycle, but unfortunately, I have run out of stock on the original batch.  There is a chance some B-stock may be available, but these are being held for the time being for a few kit developers.

We just made another change to the design today which will delay the prototype again.  2 months would be the earliest I can see bodies being back in stock.  I am, however ordering greater quantities this time, so they should remain in stock longer.  Pricing should also move in a favorable direction.

OK let me lift out a couple keywords here.
"new factory"
"standardizes"
"compatible"
"base"

While you/they are at it, how about looking at the other end of the mics, too? I'm quite fond of the big, two-layer mesh, tapered headbasket of the the SYT-5. But the 47-ish cylindrical one on the GT-2B has its good points, too. The SYT-5 body is tapered while the GT-2B is not, but where the sleeves meet the heads they are sort of close in diameter, if I'm not mistaken. Is there any chance the two headbaskets could be made compatible for both bodies. This would open up more possibilities for DIY projects. Like a long body with switches and a cylindrical head, or a short body without switches and a tapered, more transparent head (e.g. nice for poctop's straight M49 PCB; just one example of many).

Yeah, not as easy as it seems on paper, probably.
On the other hand, now's the chance.

The wheels are turning very quickly behind the scenes right now.  I will post pertinent milestone developments here as they come as well as updated timeframes for delivery.  The plan was originally to do all of this while the 1st batch of microphones was comfortably in stock, but interest has been quite a few notches higher than expected.

No need to "cobble" together bodies for various projects.  Once I get a smooth workflow going with the metal factory, development liaison, and Q/C representative on the factory floor in China, I should be able to start from clean sheet and do proper justice to projects like poctop's M49, but there are already developments along those lines state-side.  If those pan out, it may not be necessary to expend the effort in that direction.

For right now, I'm hoping the next batch of mics will carry improvements all around, and I hope to turn my attention towards a km84 project in collaboration with Matador that will involve a "clean-sheet" new body.

Can you describe some of the changes/difference you're designing with the factory? Maybe turning the SYT-5 into a 3-layer? Making the GT-2B closer to a U47? I bought a Beesneez K7 in anticipation of building a D-U47fet, but looks like I wont be able to get a body from you until the new batch...

Also, what is this KM84 project? I'm extremely intrigued. For a month or two, I've been trying to figure out the best way one might build a KM84 clone. KK84 capsules are indeed still available from Neumann, so it would just be a matter of cloning the circuit, transformer (maybe Oliver already makes one?), and body.

Are you still doing a 251 headbasket?

No, the minimum order quantity from original factory for SYT-5 is 100 units and 50 units for the GT-2B, and inside the development/production cycle for the same style bodies, I simply do not have enough liquid capital to purchase an interim shipment.  Also, there will likely be a SIGNIFICANT price decrease on the new bodies when they come in, so I would likely be stuck with a large inventory of microphones when the new ones come online or, I would simply have to delay rolling out the new bodies until the interim batch is sold.  As it stands, if the factory is indeed close to finishing prototypes right now, there is only a few weeks time difference between ordering again just like the first shipment and moving to the new bodies.

I understand that many people are frustrated with delaying their projects, but I was never happy with the price-point of the SYT-5 and GT-2B on the first shipment of microphones, and I intend to improve on that.

The headbaskets will be 3 layer much closer to the vintage originals.

2 layer headbaskets for ELA M251 builds on the HT-11A have already been prototyped, confirmed, and the order placed for production at volume.  Matador is working on doing a sample build of the ELA-type circuit right now on the current C12 pcb set.

I would jump all over that deal then at Gearslutz because that is well below the price I paid to the factory before any shipping logistics at quantity of 100 units.  That is a seriously good price.  This guy must have level 11 negotiating skills!

No guarantees of cross compatibility between the 2 bodies and headbaskets.  The new body will have to accomodate the same switch pcb in the kits, so it might be possible, but the safe assumption would be no.

Right now, I do not have spares of the switches, but I do have 3 pin XLR inserts.  Among other difficulties, the factory failed to deliver the spare switches I had requested with the first batch order, so I only have enough switches to go with the microphone bodies.

When the 2nd shipment of microphones comes or possibly when the verification prototypes are sent over, I will make sure I am well stocked on spare small parts like these switches and inserts both 3 pin and 7 pin.

Chunger I just purchased my SYT-5 body recently and have not begun my U87 build because I'm still waiting on my Hakko FX888D to arrive.

If so can I return my body I just purchased at this point since it is brand new and unused?

Also, after combing thru your u87 photo build which will be a big help I have a couple questions in regards to parts for the build. You used some hardware that you mentioned wasn't quite proper to connect the switch pcb, what would be the proper hardware and sizes? You used some brass bar to mount your transformer to the body. Do you supply that piece? If not what specific type of brass bar and what hardware store?

Last, you used a 6mm height screw to raise the height of capsule which actually made the mic look more authentic and for my application (which is vocals) should sound better based on mic positioning, where did you source that piece?

I should mention that I went to Home depot and showed the pics of the hardware but everyone looked at me strange and said that they only carried regular size hardware...So this is why I am asking for the source of your parts not included in the kit

The build procedure should not change at all with the Gen. 2 body.  All of the critical frame rail dimensions and screw holes are the same.  No additional hardware is required to mount the switch pcb.  The 3 plastic standoffs are the correct length and 3 12mm M2 screws are included to mount the switch pcb.  When I did my U87 build, I had to mount the switch pcb with whatever hardware I had available.  Now, the proper parts are included in the kit.

You will need additional M2 screws to mount the pcb's to the frame rails.  I fabricated my bracket for the T13 transformer with a piece of brass bar sourced from a local ACE hardware store, but any sheet metal that is thin enough to bend with pliers would work.  You can get a piece of aluminum sheet for roof flashing and cut it with tin snips to make the bracket if brass bar stock is not available locally.

I am still waiting for the prototype of the Gen 2 body to be finalized.  There is a chance this prototype will have dimensional problems that I have not accounted for and the kit will not be compatible.  If that is the case, there will be additional delays.  As for the headbasket difference between the SYT-5 body and the original U87, I do not find the more open mesh configuration of the SYT-5 problematic.  It is certainly different, but in our studio, we have both vintage original U87's and clones.  The clones are a bit more open with a bit more open top end.  I suspect the headbasket contributes to this sonic difference among many other differences in capsule, transformer, and electronic components.  Sometimes, we use the vintage mic . . .sometimes, we use the clone.  It all depends on the source.  The clone U87  as built in my photo thread has been outstanding in production use.

If you wish to sell your microphone body, I suggest posting in the Black Market section and email me your thread.  There are several people who have inquired about buying bodies after I ran out of stock, and I am certain you would be able to sell it without problem quickly.  If you are in Europe, it would not make much sense shipping it back across the pond.  If you experience any difficulty whatsoever, I can take the body back no problem.

any improvements to sound quality due to the new head basket?

There are pros and cons to just about anything in life.

And the proof is in the pudding.

No one has heard the two versions side by side, yet (save chunger maybe, if he has a prototype). For the time being, let me give my take on this.

First, the number of mesh layers. Three used to be the way to go (in most cases), but that was in the days before popfilters. The U67 was designed to be pop friendly. The 40 Hz high pass filter (S2 jumper) in the circuit is another measure they took to achieve this. The U67 is probably the best LDC for close approach of its day and arguably of all time. For distant recording, the C12 was/is amazing. Interestingly, that classic microphone has only one mesh layer on the basket. This allows for extra transparency, but cons can be popping, capsule contamination and RF problems.

Then to shape and size. Many seem to assume that the U67 headbasket was designed to achieve a certain sound. I'm not so sure about that. By using the wedged or trapezium shape, they obviously and clearly left the cylindrical shape of the U47 grill (as already done in the fatter M49). Rectangle as well as round spaces are known to have far from ideal acoustic properties (standing waves, focusing and such). In any case, there'll be peaks and valleys in the frequency response. So my theory is that Neumann wanted to minimize coloration rather than enhance it.
Still, a three layer basket will leave a pretty enclosed space, so some coloration will remain.

Now on to the SYT-5. The first version has a two layer mesh headbasket. In this day and age, especially with popfilters (one or two layers extra!) being used, I believe that is a very good compromise. Pretty transparent and no fear of RF. Hey , maybe that's why they say "one is lonely, two is company and three is a crowd".   ;)
But of course want we want to do here is "clone" the U67 which would imply using a three layer grill.
However, the basket on the SYT-5 is considerably larger than the one on a U67. So if the basket adds coloration, it will not be the correct coloration. In that case, or until we get something in the correct size, I think I'd rather have a less closed basket with less of a sonic footprint, if that makes sense.

Just some food for thought an an attempt to make you appreciate what you already have.  :)

But I'll repeat, the proof is in the pudding.

These headbaskets will be delivered in polished nickel plate.  If you want to powder coat or paint the headbaskets, you will need to bead blast, mask,  and coat them yourself.  Trying to keep all of the costs reasonable.

Not looking to sale my body I actually want another. Just wanted to make sure I wasn't missing anything new since I basically fell into this gap of just purchasing a gen1 body versus knowing the gen2 bodies are on the way.

In all honesty It seems most of the flaws have been worked out and dealt with with the gen1 body so for a newb this body should be easier to get help with seeing as so many have dealt with it already.

Hello dr,

Unfortunately, we are sold out of the first run SYT-5 bodies right now.  The Gen 2 bodies are in process, but it will be a couple of months before I get them in hand.

I'm also very interested in the new "Head Basket" & definitely will buy 2-4.

Also, Do you have any GT-2B in stock to sell?
I don't see them on your site but they are on the Forum.
Please let me know either way & if you don't have them in stock, when?

Thanks

Hi Chung,

I ordered a k67 capsule about 2 weeks ago. Last Saturday I was told that it went on Saturday 2-3 day priority mail. I have not received it yet. Could you please send me an update?

The order was shipped 3/29 . . . It looks like there has been a tracking update 4/7 in the San Francisco sort facility.  I presume something held up the package for a few days.  I will monitor the tracking information and hopefully it will land on the east coast soon and update again.

Sometimes the packages stick at german customs. Depending on the energy of the customs employees, the delay can be several weeks. I got packages from the USA, who spend 8 weeks Holiday in a rack at the local Customs, before they send me a notice.

Thank you in advance,

Udo.

I am uncertain still about the time-frame for this. . . the factory has the headbasket/body set up for me, but we are tweaking the internal rails still.  We will likely have a prototype within a week but I will have to confirm that all kits fit in the new body.  Once confirmed, I will place an order immediately for a production run.

If all goes well and the current prototype trajectory is good (we don't have to start over), the earliest I can see having these finished is 1 month.

Got 3 of the C-12 parts kits when the 1uf cap was not an option.
What cap do you use and where do I get one to try out?

I'm using the Erse Audio Pulse X caps sourced directly from them.  I have a bunch of other capacitors on-hand for testing, but have not had a chance to experiment with them.  The Erse seems to be working quite well and I am trying to determine difference between the AMI T14 and Cinemag 2480 right now so I am running the .56uF Erse in my prototypes currently.

Caps that fit.

Solen MKP-FC 1uf 630V
Solen MKP-FC .56uf 630V
Mundorf Mcap ZN .68uf 250V (barely fits)
Mundorf MKP 1.5uf 400V
Mundorf MKP 1uf 400V
Mundorf MKP .56uf 400V
Sonicap Gen II .68uf 600V
Sonicap Gen I 1uf 1uf 200V
Erse .56uf 630V
Erse 1uf 630V


Caps that might fit with a bit of modding/cutting on PCB (barely too big to fit)

Sonicap Gen II .82uf 600V
V-cap OIMP 1uf 250V

Custom headbaskets will be shipping by air.  I have been getting a lot of pressure from anxious people for these headbaskets, so I shipped them all by air.  They should arrive in the next couple of days.

A note for people planning their builds.

The next shipment of HT-11A bodies will include the modified headbasket and will cost $190.  So, if you are planning to by my body when they come back in stock, it is best NOT to pre-order a headbasket at this time.  If you already have a body from the first batch or are using Apex 460 or Carvin or other donor body for the C12 build, feel free to order headbaskets as soon as they come in stock.

SYT-5 and GT-2B revision 2 bodies are still at the prototyping stage.  I should be getting first prototypes soon on these are ready and will post pictures and report back if all current microphone kits fit these bodies.

Hello Aaron,

The testing we have been conducting with Tim's capsule in stock form have been going well.  Originally, we had hoped he would be able to build up the microphone and give an opinion on optimization, but he has not had the spare time to build up the mic kit I sent him. . . the increase in capsule demand generated from this project probably doesn't help  :o .

I just ordered a bulk of NOS 6072A tubes from Christian Whitmore.  Once the new batch of donor microphones arrives, we should be able to offer everything except for the capsule.  That's pretty darn close to a full kit.  It will take a bit of time for me to recover enough financially from the large China order to buy a quantity of Tim's capsules.  Once those are in hand, full kits will be available. . . probably 6-10 of them initially.  After that, I will have to figure out the logistics of keeping them in stock.

Looking forward to the next update.

Keep up the good work!

I would stay persistent until he responds and indicates that you have a spot in line.  Persistent, but keep in mind he probably responds to emails in batches every 3 or 4 days.  Once you are in the build queue, there is no need for further contact as Tim will update and invoice you when the capsule is near completion.  At least that's how it went for me.

You might with to try using a different email account just in case his spam filter is kicking your emails to his spam folder?

Good news.  Headbaskets should be arriving next week and I have a tracking number.  The least expensive shipping route took them over land in China for a stretch before flying over the pond.

Bad news on HT-11A microphones.  The Alctron factory reports one of their suppliers messed up a part and they must remake it.  We are delayed one additional month.  ETA 2nd half of July.

Prototype for GT-2B and SYT-5 bodies also incurred a slight delay.  Outer bodies and headbaskets are complete, but the internal rails for the sample are being remade.

Bummer on the HT-11A.  Did you say hey will include the custom headbasket?  Will there be a choice of single or double layer grill?  Also, will the original headbasket still be included?  Just wondering because I had some plans for the leftover headbaskets.  Thanks Chunger.

Also, if you hear from Tim maybe give us an update in this thread on what has been delaying his responses?

Yes, there will be a choice of single or double layer headbasket on next batch of HT-11A.  No, they will not include the original type headbasket.   I'm pretty sure you will be able to find an original one on the used market for your needs on the cheap.  I know I have about 3 of them on hand at the moment.

I'll ping Tim and see what is happening.  Perhaps vacation or something?

Post by: chunger on May 12, 2013, 12:41:18 AM
Update from Tim Campbell regarding his recent lapse in email responses.

Our little venture here has increased sales volume much more than expected.  Keep in mind, until now, Tim's normal production volume was ~20 units per month on these hand-made capsules.  Quality from the 3 samples that I have seen has never waivered.  Capsule reservations from this project alone are at about 30 units per month.  Also keep in mind Tim has "regular" customers from other avenues as well as commercial customers.  So, everyone should stop buying those mics that he OEM's capsules for  :o . . I kid, I kid.  Those are some pretty amazing commercially available mics that use his capsules.

So, due to the recent surge in demand, Tim has not been able to accurately gauge his lead times like he used to.  He is taking steps to streamline his workflow and add equipment (Additional CNC machine and find additional staff) to his operation, but this sort of ramp-up takes time.

Adding to the mess is the fact that in Denmark, it is getting very near tax time and he is planning a vacation with his family about 6 weeks from now.

Tim has assured me that he will catch up to email requests shortly and get everyone in the queue in the order of inquiry, but the unfortunate thing is capsule orders placed at this time may likely not be fulfilled until September.  He has never had to extend his lead times past 10 weeks before now.

Tim and I both are feeling the effects of increased demand on this project.  I too am currently running a solid 11 days behind in shipping orders out and it has been as bad as 16 days this month. . . because you guys cleaned me out on my first batch of electronic parts kits and I'm just this evening finishing sorting and bagging the 2nd batch.

I'm not sure if I mentioned it previously, but HT-11A bodies have been delayed 1 month also due to one of Alctron's suppliers messing up a part that has to be re-made.  We are looking at July now for these bodies to come back in stock.  But, I doubled up my quantities, so hopefully, these will stay in stock longer this time around.  It's worth mentioning again the new shipment of microphones will include the custom headbasket (your choice of mesh configuration) as standard.  They will not come with the original Alctron-type headbaskets since most people myself included cannibalize them and will likely not use them once the custom ones arrive.

I agree stay the course but don't kill yourself. Please tell Tim to take his time as well. Vacation with the family is needed and should be done without any regrets. Thank You Chunger for all you have done and please don't let it mess up your life. I am sure we can all hark back to the days when all of this was a distant dream, remembering what fun it was having unbridled anticipation. Its like waiting for your birthday when your little all over again. Yippee!

Headbaskets are live in the webstore.  There is one problem with the order that I am quite upset about.

The requested bend in the metal hoop that I specifically requested and was promised would be executed is NOT correct on the production batch.  I'm pretty darn mad about this  >:(  and am going to have some words with the factory about it, but the headbaskets in general look nice and are exactly like the photos on the webstore and on this thread.

All are in stock.  I am currently 14 days behind in general shipping and there will be a surge in orders because of this new product, so I apologize in advance for the longer-than-normal turn-around time for orders.  I did not have the item live more than 5 minutes before I received 3 orders.

Mark

perhaps updating your storefront to 'out of stock' or 'backordered'? frustrating to wait a week after payment and no receipt to find out I have to wait 2 more weeks plus shipping time.

I apologize for the delays.  If you would like a refund at any time, please contact me.  Not many people are able to run DIY as a full time gig, so we try to do the best we can with the time we have.  An influx of orders or the need to sort a batch of components can easily overwhelm a single-person operation.  I try to keep information up-to-speed on this thread and remain responsive to email inquiries.  All items listed as in-stock in my webstore are in-fact physically in stock.  The bottleneck is sorting components and getting boxes shipped out right now. 

The current situation is, orders placed 4/29 - 3/3 are packing tonight and shipping tomorrow.  Orders are being fulfilled in the order received with the rare exceptions like pending recording sessions, etc.

Hello there,
Is there a waiting list I could be added to for the SYT-5 microphone body? I'm trying to piece together a clone and the body is my first big obstacle.

I understand you're busy and had a delayed shipment to you (per your previous post), but just thought I would check.

Thanks.

Hi Chunger,

thanks for your work. You just got an order about 2 complete sets.
It's going to germany, if someone would like to chime in.

This time around all of us in the EU should perhaps come up with a plan. I bought a SYT-5 body earlier on and the extra costs weren't funny. And that was even without a case.
If we could hold out until all parts are in stock (I'm in no real hurry) it should be possible to do one big shipment to one address in Europe. Or will there be many separate boxes anyway?
 
Unfortunately I don't have the funds to pay a large lot in advance. Anyone here (in the EU) who could act as a "central station"? And maybe chunger has a solution for the financial logistics in such a scenario?

The shipping charges are no joke. . . headbaskets can ship pretty easily.  A flat rate envelope (with a box stuffed inside) can ship 4 headbaskets for ~$24.  But, this is the smallest unit I can ship to Europe so the shipping cost for 1 headbasket is also ~$24.

A medium flat rate box is about $60.  I have not tried to see how many I can fit inside of one, but defintely 20 and possibly even 30 headbaskets can fit inside of one box.  If someone wants to coordinate a mini group buy for Europe, Australia, or Canada, I'm just fine with shipping these to one location.

There really isn't an easy way around the weight of shipping the complete HT-11A microphone at over 11 lbs. a piece.  At that point, any additional components are merely incidental to the weight of the microphone.

Paypal does not allow me to print standard parcel service labels for international orders.  So, it is possible to ship cheaper, but there is no tracking and I have to go to the post office in person and invoice each package separately as well as fill out customs forms for each one individually.  The time required supercedes the cost savings especially if I am already having trouble keeping up shipping orders out in a timely manner.

Bad news on HT-11A microphones.  The Alctron factory reports one of their suppliers messed up a part and they must remake it.  We are delayed one additional month.  ETA 2nd half of July.
Prototype for GT-2B and SYT-5 bodies also incurred a slight delay.  Outer bodies and headbaskets are complete, but the internal rails for the sample are being remade.

Chunger are you going to get the screw on shock mounts that came with the GT-2B kits a la cart?

I have that ability. . . one of the requests I made that has delayed the prototype microphones is utilize the same base-piece thread size as the SYT-5 and GT-2B on the Rev. 2 prototypes.  I think that was a good move because now, the shockmounts can be standard across both generations.

hi Beeswax,

As soon as these become available, I will put them up on the webstore for sale.  At this point, I do not have a definite timeline.  The first verification prototype should be completed very soon and I will post photos when I get that unit in hand and confirm that all of the currently available pcb kits fit in the revised body.  I am ordering significant quantities of this body (150-200 units) so they should remain in stock for some time.  Also, follow-up orders should be much faster than the initial ramp-up to get the microphone to our specs.

For everyone who has placed headbasket orders recently,  please contact me if there are any additional charges or anomalies with the shipping.

One customer has reported a shipping surcharge because I stuff a box inside of a USPS flat rate envelope in order to accomodate the headbasket and keep the shipping costs reasonable.

I am particularly concerned with the international shipments that have gone out because if I am not able to pack the shipments this way, the shipping costs would be astronomical.  I would appreciate a quick email when your shipment arrives to let me know if things are ok or if there have been problems.  From what I can read on various other types of forums, some post offices may have a problem with this packing methodology but most will not not.  There is a 4 lb. maximum weight for these envelopes which we are well under on all boxes that have gone out.

The SYT-5 body sleeve is an exact continuation of the Behringer Pro-2 sleeve, as I've shown here:
http://www.groupdiy.com/index.php?topic=50197.msg649158#msg649158 (http://www.groupdiy.com/index.php?topic=50197.msg649158#msg649158)
The Behringer is smaller than a U67/87, the SYT-5 is bigger.
Since you've pushed the SYT-5 to generation 2 (from a new manufacturer even, if I'm not mistaken), have you considered getting it closer to the Neumann size, or would that cause problems with Dan's PCBs?

Hello Yanki,

I respectfully decline to reveal the specific factories that I work with and disclose my industry contacts inside of China to anyone who asks on the internet at this time.  I am still relatively new to the manufacture and import business and am still learning the ropes and blundering through the various ins and outs of developing good working relationships with the right suppliers.

A lot of doors open up through referrals, but the tricky part about it is, the reputation of the person who is doing the referring rides on who they refer.  My first contact inside of China came from a friend who I had been doing A/V install work in the US with for more than 7 years.  He referred me based on his confidence in my ability to foster a mutually beneficial and profitable relationship with the contact he referred me to inside of China based on our long-standing relationship.  If I deal poorly with my new Chinese contact, it reflects poorly on my friend.

I am just starting out with many of my Chinese vendors and contacts and need to establish a good track record and that simply takes time.  While I am in my 1st or 2nd production run, I can ill-afford to refer people that I do not know very well because it would reflect poorly on me if something goes wrong.  Once I generate 10, 20, 30, 100 good deals and along the way, successfully refer a few of my closer friends and collaborators, I might be able to be less selective about who I refer directly to my long-standing partners overseas. .. but in the beginning before I have established a reputation of being a valuable customer, I need to be careful and focus on working out my internal problems.

This may not be how many people operate, but it is how I am trying to move forward.

I believe I contribute to the collective knowledge base in many ways and am much more "open source" about what I'm up to than many vendors and manufacturers.  I also document and evangelize other people's kits and products with the same enthusiasm here.  Or, I try to be anyways.  But, there is tremendous personal risk every time I pull the trigger on a large-quantity order from a Chinese factory because there is no guarantee that the product will be to the required quality standard or for that matter, even work.  I will take the wise advise of people who have done this much longer than I have and unapologetically retain some proprietary information in regards to my parts sources.

UPDATE:

We have good news and bad news in regards to microphone prototypes.  They arrived this morning.  I will talk about the Gen. 2 SYT-5 because this is close to production at scale.  It is a chicken/egg sort of problem here and I took the path of tailoring the microphone around the existing kits that are available and making sure they are all compatible with the Gen. 2 body.  In particular, the DU67 and DU87 family of pcb kits that Poctop designed and distributes http://www.vintagemicrophonepcbkit.com (http://www.vintagemicrophonepcbkit.com).

The main piece of bad news is the factory failed to execute the specified 3 layer mesh configuration.  The 2 layer sample has a closer spec'd (finer) inner layer than the 1st Gen SYT-5, but I am pressing for the proper materials to be sourced.  This is the biggest disappointment with the prototype, but I am increasingly confident I can get this done right for the actual production run.

(http://studio939.zenfolio.com/img/s11/v35/p1825472455-4.jpg)

(http://studio939.zenfolio.com/img/s9/v89/p1625709169-4.jpg)

We have changed to what I feel is a higher-quality rubber capsule mount that still fits the 35mm capsule from the Gen. 1 microphone and I am sure can be modified easily (1 drill hole) to fit an original reproduction K76 capsule, Peluso, or any other 34mm variant.

The general mechanical fit of the components is much tighter tolerance than the first Gen microphone especially at the mating point between the headbasket and the body tube and I am most pleased with how the factory has tightened up the tolerances around the switches.  This body was designed around Poctop's switch PCB and the switches sit perfectly in the tube.

(http://studio939.zenfolio.com/img/s9/v92/p1746484852-4.jpg)

The DU67 that utilizes ioaudio's transformer is the longest single PCB for this project and it fits perfectly.

(http://studio939.zenfolio.com/img/s8/v78/p1759471414-4.jpg)

(http://studio939.zenfolio.com/img/s9/v92/p1692969329-4.jpg)

The tightest-fitting build options is the DU67 kit that utilizes the AMI T67 transformer along with it's separate mounting pcb and this also fits like the Gen. 1 body.

(http://studio939.zenfolio.com/img/s8/v80/p1700403267-4.jpg)

We do have physical contact between the transformer's outer laminations and the body of the tube but the microphone does assemble completely with the transformer in place.  This occurs on my sample of the Gen. 1 body as well as the Gen. 2 body.  The Gen 1 body has a relief cut inside the body tube which may allow a hair more clearance.  I hesitate to replicate this relief cut in the gen2 body because all of the B-stock Gen 1 bodies were damaged in this area where the relief was cut on the body tube.  It creates a very thin and vulnerable spot at the bottom of the tube.  The sure way to ensure no contact whatsoever between the transformer laminations and the microphone body is to cut a small portion of the frame rail which would allow the transformer to drop deeper into the center of the body and clear the outer body tube.

Yes, I received a prototype for the GT-2B gen 2 microphone and all of the existing pcb's fit the new body which is good, but the body was based on a 52mm diameter tube instead of the nominal 60mm tube for U47 type mics.  The mistake was mine because in order to keep the final cost of the microphone low, I advised the factory to pay particular attention to the internal dimensions, rail configuration, and headbasket mesh. . .  and use the path of least resistance for the rest.

So, the gen 2 GT-2B body is not as close to production as the SYT-5 gen 2 bodies.  The good news is, the factory does have a 60mm body and we have already done the work to make the rail setup.  I also included 2 more mount points in the rails at Poctop's request for mounting transformers, so this should work out well.  I do apologize for the extended delay, but I think a better spec'd microphone at ~$60 per unit price reduction is worth it in the long run and should put some of these mic projects within reach and maybe allow folks to build multiple microphones when they could only build singles before.

No need to apologize, I agree that a better product is worth the wait and I appreciate your effort.  I also plan on needing more than one unit so a reduction in cost is great news!

I just finished ordering all of the parts for another 100 parts kits.  It looks like there were enough parts in-stock from various electronics parts vendors for about 20 more kits and all back-ordered parts should be in stock 6/18, so I think I may revert the status to "in-stock" again so that people don't feel a need to panic buy when they come back online.  We are still experiencing shipping delays of about 11 days currently.  I have not yet been able to stabilize my processes and find enough free time to get 100% caught up.

Monitor the white market thread for general updates.  Nothing has changed on the HT-11A order.  I placed the order a while ago, and the factory should complete the production run in mid-July.  Sometimes they are faster than their projected lead times, and if that is the case, I will update immediately.

status update:

HT-11A's are still on-track and being built at the factory.  I will hear from them as soon as this production run is complete.

For the Gen. 2 SYT-5 and GT-2B bodies, the ball is in my court.  We are back and forth a little bit on the headbasket mesh specifications, so I am procuring brass mesh samples to nail down my exact mesh specifications and materials here in the US.  Once I send these samples to the factory, they will match and source materials for actual production from their regular suppliers, but they wanted to have the correct materials physically in their hands to be sure.  It is a little bit backwards because some of the sample mesh materials that I am getting come from Chinese factories, but better to be sure and get it right the first time.

I appreciate everyone's patience as we sort out these important details.  Once we get past this development phase, we should be able to get bodies out to everyone.  I know many people have been waiting.

hello Andy,

I currently have a dual layer headbasket that is made from the same tooling as the C12 headbasket.  The outer layer is the same and it adds a finer inner layer.  These are in stock and shipping.

Planned for simultaneous shipping with the HT-11A microphones is a shorter hoop-type headbasket with sharper curve radius that tracks a bit closer to the ELA M251 headbasket.  This also has a tighter mesh configuration (both outside and inside layers) than the currently available 2 layer headbasket.

So, right now, I have a dual layer headbasket that will work well, but when the new batch of donor microphones arrives, we will have 3 headbasket options.

1.  Single layer (currently available)
2.  Dual layer (currently available)
3.  Short dual layer with tighter mesh (ETA mid-July)

All will be polished nickel plate.  Keep in mind, new donor microphones will not have the option of the standard Alctron HT-11A headbasket.  You will have these 3 headbasket options to choose from when ordering.

Hello All,

Not much to update.  I am on vacation.  I tried clearing the shipping queue prior to leaving, but did not get to all outstanding orders.  Please feel free to contact me for refund if the wait time is too long.  I emailed the people who have been waiting the longest to update them on the situation.  I will return in ~1.2 weeks.

I will be getting capsule mounts back in stock.  Actually, I'll have a few options for capsule mounts upon my next shipment so this is good.  They may take a while to get in stock though because the 35mm K67 capsules are not in stock at the factory and need to be made for me.  Because there was a lot of interest in the mounts by themselves, I have ordered a significant number of bare mounts to try and keep these in stock.

HT-11A microphones should be ready any day now.  I have had a bit of chatter from the factory finalizing a few details, so I have a feeling they are close.  I am away, but have uninterrupted net access, so as usual, please feel free to ask if you have questions.

No significant updates on the gen 2 STY-5 bodies.  I just received and prepared mesh samples for the proper 3 layer configuration and am sending my physical samples off to China for the factory to match.  That is the final detail.  The rest of the mic is good to go.  Once I get confirmation that they have successfully sourced materials and matched our meshing, we should be good to go for production.

Awesome!  Choice of headbaskets or just the single layer?  Will the headbaskets be the same or did you correct them? (I remember you saying somethign wasn't done exactly as you would have liked).

Super excited to get my hands on these and assemble these mics!  Then on to the MK47.

Alctron has a few ribbon microphone models that would be very easy to order.  I do not personally know much about modding these Chinese ribbon microphones, but it would be easy enough for me to order some in the next shipment.  Take a look at the Alctron microphones and please let me know if any of the models look particularly interesting.

Update:

Shipment is scheduled to land August 16.  This shipment will contain:

- HT-11A donor microphones
- 35mm K67 type capsules
- 35mm white capsule mounts

We are having some production problems with the custom C12 headbaskets with the factory, but stock is still healthy from the first production run/order.  They are unwilling to implement the changes requested to make the headbaskets according to original specs.  I am trying to recover the tooling that was made for me (paid complete tooling costs) and shift production to another factory.  Quality should improve, but price may increase slightly.

Mesh sample materials for the Gen 2 SYT-5 bodies have been received by my associate in China, so I am hoping a large production run of the gen 2 bodies will move forward quickly as all other aspects of the prototype were spot on.  Headbasket dimensions were compatible with first generation syt-5 microphones, so I will be ordering spares for people to purchase separately if they want to upgrade first generation bodies to the new headbasket.  I will also order spare microphone tubes for people who have mis-marked bodies on the pattern switch. 

Mesh samples for the Gen 2 GT-2B bodies have also been received.  I am making a few changes to the original specification on the GT-2B bodies, so these will take a little longer to iron out.  The final product should be rather spectacular though for the short-body 47 type microphone body.  This will likely be a proper 60mm tube body with 3 rail internal setup at 90 degrees. . . with sheetmetal inserts to make the body drop-in compatible with all rectangular PCB's designed around the 1st gen GT-2B bodies (FET47, mk47, M49, etc.)

This makes that already versatile body even more versatile.

So now we need differently colored body sleeves to tell them all apart.  :P
How about bold primary colors?
Hey, that would include yellow.  :o

Yes, this is a DIY forum. But the bodies are ready-made anyway.  ;)

Post by: chunger on July 30, 2013, 02:21:37 PM
There was a bend in the metal the hoop piece where it attaches to the base that I specified to make the hoop more flush with the outside edge of the headbasket.  The factory promised that this specific bend would be executed in the production batch.  I ordered without a verification sample based on this promise.  The headbaskets all arrived without this bend.  First, the factory claimed the bend was there and I had to dis-assemble a headbasket with a torch and send photos to prove the hoop was in fact straight all the way through.  Then, the factory agreed to make the change and compensate a number of headbaskets to make up for the error.  I offered to place another somewhat large order on top of these make-up units immediately so the factory did not have to make a "small" production run.  After delays, the factory said their metal sub-contractor refused to make the bend for them.  At this point, I decided it would be simply easier to stay with the same manufacturer and forego the bend and accept the agreed compensation units and place the same order as agreed upon without the bend.  Then, the factory said the single layer headbaskets had a lot of rejects in the production run and the mesh was hard to align straight and solder cleanly so they do not want to make single layer headbaskets and they will not compensate any units for their error.  Probably more than 85% of the sales are single layer, so after all of this, I decided to pull the plug on this factory as I have been trying to work with them, but too many reversals on agreements when they did not deliver as promised despite my efforts to make it worth their while.  I have demonstrated already that I can buy at volume but they don't seem to want the business.  I have paid the entire tooling cost in full, so I should not have problems getting the tooling from the factory, so I have requested they send me the tooling.  I have arranged for another factory to make the headbasket.  I would not be surprised if the original factory refuses to relinquish the tooling though :-\ .  Such is the nature of doing business in China.

I still have enough stock of headbaskets of each type to cover all of the donor bodies in this shipment.  I did order a TON of them and even with steady sales, I still have quite a supply in stock.  For this run of HT-11A's, there will be 3 headbasket options to choose from:

1.  single layer (my design)
2.  dual layer (my design)
3.  dual layer short (closest to ELA M251 see picture below)

I am dealing directly with a primary factory now.  I like to keep working with companies that can get things done and deliver as agreed reliably.  So if these guys had come through for me I would have stayed with them for the c12 headbaskets. 

All headbaskets for the ht-11a that I am bringing in are polished nickel plated.  The sample pictured is unfinished brass for the type 3 headbasket.

Thanks for keeping up the hard work!

Hmmm. . . apparently another vendor on forum is attempting to sell my headbaskets now.    >:(

Likely sourced from Alctron because unfortunately, the microphone company I solicited originally to develop the headbasket shares the same metal sub-contractor as Alctron (I was unaware of this at the time).  I was hoping this would not happen so quickly, but such are the dangers of doing business in China.

Fortunately, I have recovered the original tooling that I paid a significant amount of money for and the factory will be unable to produce further copies at low volume to other customers without re-tooling.  But, once your design gets out in China, it's a free-for-all.  I am transferring tooling and production to a more secure factory where I actually have eyes on the ground. . .and, hopefully, they will be able to get the bend in the metal where the hoop meets the base correct in the next production run and improve the finish quality as well as mesh alignment on the single-layer headbaskets.

Well, I am confident quality improvements and pricing improvements on all of the 2nd Gen. products will be VERY tough to compete with.  Definitely worth the wait in regards to the extra development time needed to bring them online.

Updating specs for the rev. 2 GT-2B bodies.  I decided to go to a 60mm body tube, 3 rail 90 degree frame, and a much closer U47-type headbasket configuration.  I was a little bit unhappy that the tube length ended up a bit longer than the original U47 FET shorty body to my eye, but I thought it was important to fit the mk47, FET47, M49, and other currently available kits inside of this body because I think it will be the most economical option for many builders.  New pcb's will be able to utilize keystone L-brackets.  I have spaced frame rail holes at hopefully a convenient 20mm interval.

(http://studio939.zenfolio.com/img/s8/v79/p1719383658-6.jpg)

The internal spacing of the rails becomes wider than the original gt-2b and many PCB's are based on that design, so my solution is to make adapter brackets so that all currently available gt-2b kits will drop right in with no additional metalwork and a very clean install.  Also, poctop requested an additional mounting point integrated into the new mic for his sub-PCB that mounts AMI T49 transformers, so that extra set of holes 24.5mm below the original 2 holes has been integrated into the adapter bracket per his request.

(http://studio939.zenfolio.com/img/s10/v110/p1748123944-5.jpg)

I plan to use a screw-on type shockmount for this microphone, and it should be cross-compatible with the SYT-5 shock mount, so hopefully this will make studio life simpler for people who are building up their kit.  Possible future features/versions of this body:

1.  slotted tube for switch mounting
2.  128mm tube length version for folks who like the vintage short U47 look
3.  Pre-drilled/tapped holes in the base for surface-mount resistor (for mk47 kit)

On my next order from Alctron, I will bring in a small amount of these ribbon microphones to test the waters. . . small meaning 10-20 units of a few models. . . people who want to do some experimentation and development on these bodies will have a chance to get hands-on.  I'm sure cost will be quite reasonable.  If some of these prove effective and popular, I can order serious quantity in subsequent shipments.

Received confirmation today that tooling for C12 headbaskets is physically in my associate's possession in China. . . hopefully this will deter poaching for a little while depending on how many extras the factory pressed out before they sent off the tooling  :o  At any rate, my tooling is on its way to another metal factory where controls are tighter.

Full speed ahead.  I'm really pressing to get these gen. 2 GT-2B and SYT-5 bodies finalized and available.  They are shaping up to be fantastic.  The ball is now in the factory's court because they have all of the specs and details.  I anticipate some lively communications in the next couple of weeks to clarify and finalize the prototypes.

HT-11A's, 35mm K67 type capsules, and capsule mounts are crossing the ocean now.

Updating specs for the rev. 2 GT-2B bodies.  I decided to go to a 60mm body tube, 3 rail 90 degree frame, and a much closer U47-type headbasket configuration.  I was a little bit unhappy that the tube length ended up a bit longer than the original U47 FET shorty body to my eye, but I thought it was important to fit the mk47, FET47, M49, and other currently available kits inside of this body because I think it will be the most economical option for many builders.

Yep, this is going to be a pretty versatile body. Could become a classic for the DIY world even.
Will there be a polished nickel ("chrome") headbasket and bottom bell, or perhaps an option for that? I kinda like that look on the Stellar mics. Also, it would look better if builders decide to paint the sleeves (handy if there are multiple flavors inside). Less true to a U47 body maybe, but it ain't that (nor an M49) anyway.

Oh, and now that the GT-2B body is widened, will the headbasket of the SYT-5 fit on it (and vice versa)? Talk about versatility.

Sorry if any of this was already covered. There's quite a bit of info here.

Anyway, thanks again for the efforts.

Post by: chunger on August 07, 2013, 04:25:43 PM
I don't want to guarantee anything on pricing at this point, but I aim to make a significant price drop on Gen. 2 bodies.  This is possible because I bypass the microphone OEM and deal directly with the metal factory and buying only the necessary parts.  I need to wait and see before nailing down pricing because I am adding features and this makes the build a bit more complex for the factory but I think these details are important to get right.

The way I see it, the pricing is going to determine if people will see these as "novel one-off" projects or affordable tools that they can outfit their entire studio with, experiment and develop new kits, and build stereo pairs, etc.  I want these to be a no-brainer value wise for the DIY'er.  If I can get the cost in line, I think these have a good chance of becoming go-to donors for many current and future projects.

Shipping overseas can be a lot cheaper if I do not include the whole kit, so I'm planning to make bulky accessory items like cases optional.  These details are still being ironed out.  I need prototypes in hand before I am able to have cases made.  I'm also exploring ways to streamline the cases (multiple mics in one case for example). . . perhaps cases formed to store mics in their shockmounts to save space.  I'm thinking through a lot of these variables with shipping cost in mind.  I will have to talk to the case factory guys to see if some of these ideas are possible like one case with interchangeable foam inserts for STY-5, GT-2B, or HT-11A so a customer can order say, 2 mics of whatever type they desire and have them shipped in a single case.  The PSU is another concern.  Collectivecases.com makes a nice psu enclosure that lots of people are using, but a case would be pretty bulky if I make a slot for that psu.  Domestic shipping wouldn't be a problem, but international I'm not sure.

Update:

The shipment of HT-11A microphones landed in port on the 14th of August, but now, the container has been upgraded to "intensive search", so we are experiencing delays in clearing the cargo.  We are now officially in a holding pattern before we can clear customs.  Sorry for the delays.

Final (hopefully) prototypes for SYT-5 and GT-2B microphones are being fabricated right now by the Chinese factory per my updated specs.  Both will share a 24mm threaded shock mount.  If all goes well, we may be in production soon.  I am fairly confident the SYT-5 will be spot on as the changes requested were fairly minor.  Match mesh materials to the provided sample, allow a bit more exposed thread at the base to solidly secure the shockmount, and clearance cut the inside bottom of the tube to provide a little more space for the AMI T67 transformer for poctop's DU67 kits.

The GT-2B specs have all been sent in, but I'll have to wait and see if we need to make any tweaks or corrections.

So Chunger, the tall single layer is based on the C12.  The new short basket is obviously ELAM251 inspired.  Did the larger dual mesh design ever appear in a production mic of old or is it a personal twist (combo) between the C12 and ELAM design?

It did not. . . the ELAM inspired headbasket was NOT my design so I do not claim credit for it.  Several other OEM Chinese mics have it so I tracked it down.  It was also offered to me as an alternate initially when I proposed my custom headbasket design for manufacture.  When drawing up my custom headbasket, I had to choose between either the C12 look or the ELA look and I chose C12.  Wanting a dual layer option, but not wanting to do tooling for 2 different shapes, I decided to do a dual layer variant of the design I made.  I think the Type 2 dual layer option is still valid though in case someone simply prefers the sonics of the dual layer or is uncomfortable exposing their premium capsule to the very open single layer setup.  To be quite honest, I think the Type 1 and Type 3 setups will dominate sales and I will be holding onto Type 2 stock for some time.  Luckily I planned accordingly.

The psu is set up with a switch to change between 110 and 220.  We retain the factory power transformer and mains wiring in the kit so you will not have any difficulties.  I do not charge any extra fees beyond shipping but taxes and tarrifs may be imposed upon import to some countries.

Looked into ribbon microphones from Alctron because it looks like I will need to make a follow-up order very soon.  They say they no longer make the RM-21 or the SRM-100 microphones and only offer the RM-10.  It looks like an interesting microphone.  I know a ribbon has been requested by a few people for modding and I think I can sell these for ~$100 USD.  Minimum quantity is 50 so I'd have to jump in with both feet.

I can check with other OEM's to see if anyone else offers a near-identical version.

According to the web site, the ribbon motor in the RM-10 and RM-21 is the same:


Ribbon type & Dimensions:Pure aluminum,2.5 microns thick,35mm x 5 mm you(L x W)


Hey Chunger, what about the RM-15?  That looks suspiciously close to a Cascade Fathead.

I can check with other OEM's to see if anyone else offers a near-identical version.

...just as a point of reference, it's critical that you verify the actual ribbon thickness that will be supplied...many of the OEM chinese ribbon mics claim 2.5 micron ribbon thickness but actually deliver 5-6 micron aluminum ribbon foil (not good)...it's much easier to work with the thicker foil from the manufacturer's standpoint (less delicate = less waste in the manufacturing process)...

...second, keep in mind that while “Medium Ribbon / Long Path” mics like the RM-10 and Fathead are excellent for some instrument/guitar cab micing duties, they don't excel on vocals...the “Long Ribbon / Short Path” types, like the Alctron RM-21 and RM-8B, exhibit extended top-end response and work well on vocals as well as piano, string, reed and brass instruments...I am currently tracking female vocals with a Cascade Victor (long-ribbon mic) with wonderful results (I can post clips if requested)...

...Chunger, the other concern I have for you as the vendor/supplier is that these mics (from a very reliable and familiar OEM manufacturer) are already available here in the states for under $80, and that price "includes one FREE no-hassle re-ribboning service and a lifetime guarantee on none-ribbon components"...is it worthwhile for you to compete with that?...might your investment be better placed elsewhere?...I say this as a friend...I can post a link to these $79 ribbon mics (both a “Medium Ribbon / Long Path” Fathead-style and “Long Ribbon / Short Path” Apex 205-style) if requested...

...if you haven't read this explanation of different chinese ribbon mic categories, it's very beneficial:

Hey Kidvybes,

Thanks for the heads up.  I am just following up on customer interest here and do not have extensive knowledge of ribbon mics or the mod process.  My assumption was that any serious DIY would replace the ribbon or modify the motor with known premium components.

If other vendors are selling mics WITH servicing at $80, and the medium length ribbon is not a desirable configuration, I should at minimum be looking elsewhere besides Alctron as a source but more likely not jump into a head-to-head competition with large volume distributors.  My guess is that Alctron is maintaining their "non-problematic" products from a manufacturing standpoint. 

More research!

...it may be more beneficial for you to look into the empty body/headbaskets without the pre-assembled ribbon motor and chinese transformer, and offer the components (ribbon foil, un-assembled motor w/magnets, and premium transformers) individually for the DIY crew...more like your other products (but you already know this  ;))...while I've seen vendors for foil, gears for crimping foil, pre-assembled ribbon motors, and transformers, I have yet to see any ribbon-mic bodies being offered by anybody...I wish you continued success!

Maybe I'm less "in the know" than others here, but I'd like to know where I can get $79 re-ribboned fat-head like mics. 
You could link me via PM or the thread.

In ON TOPIC news, I've built both mics and power supplies that I ordered from chunger.  I'm awaiting Cinemag transformers (which are out of stock and look like a 3week lead time) and I'm also waiting on a pair of Tim Cambell capsules. 

Everything went together perfectly first time, and the voltages look good on first power up!!!

I was really afraid of the .1 cap being to big for the sleeve after reading through chungers fantastic step by step documentation, but after roughing it in, there is actually quite a bit of room in there!!! 

I'm already excited about doing a U47 pair next!!!!

Maybe I'm less "in the know" than others here, but I'd like to know where I can get $79 re-ribboned fat-head like mics. 

Fathead style (medium ribbon/long path): http://www.jrrshop.com/nos-r5-lollipop-ribbon-bass-microphone
Apex 205 style (long ribbon/short path): http://www.jrrshop.com/nos-r2-blue-ribbon-guitar-microphone

From the product descriptions:
"Each & every R2/R5 Ribbon is hand-picked & -tested in the USA. NOS backs the R2 with a lifetime warranty for all non-ribbon components, with a one-time, no-questions-asked replacement warranty for the ribbon element itself. The R2/R5 ships in a durable aluminum travel case."

...there's even a pop-up "Take $5 off any purchase of $75 or more" coupon, bringing the price down to $74 before shipping...

...I only offered up this info with the best intentions of alerting Chunger to what he might be competing with prior to making decisions to invest in new product inventory...I appreciate his (and Matador's) hard work and dedication, not to mention financial commitments, to making these DIY products available...

Hi DAn,

I am VERY close to seeing the "hopefully" final prototype for both GT-2B and SYT-5 microphones.   The last interactions I had with the metal factory were discussing the nickel plating.  They were supposed to have completed the samples last week, but there was a Chinese holiday with 3 vacation days, so hopefully they will be sending the sample to my associate soon who will  take a few pictures for me to verify that the changes I requested have been executed properly.

So, we are still in a holding pattern, but I'm hoping to have good news in the next few days.  Monitor this thread for the latest updates.

If the requested specifications are all met in the prototypes, we will immediately move forward to a production run that should not sell out for quite a few months.  Even if only one of the microphones is correct, i will move forward with production and import of the single "good" model right away.  The SYT-5 was almost perfect in the previous sample, so i am confident these will at least be good as the requested changes were very slight.

Hi Chunger,

I'm just wondering how far off the rev 2 with ELA M251 version of the PCB is? I know you mentioned we could hack the current PCB but I'd rather wait until you guys have vetted it and have the PCB updated.

I understand you've been swamped so I take that into consideration. But then again, in the big picture that's a good thing right! Mo' sales is good!

Thanks,

Mike

UPDATE:

We are now on revision 1.2 of the C12 pcb set.  Only the slightest of changes was implemented on the revision.  The board was lengthened by .060" to give slightly more length to the output capacitor slot.  The V-cap 250V 1uF OIMP type capacitor now fits without mods.  Since the kit-supplied Erse units have been working superbly in stock .56uF and 1uF options, I have not had a chance to test these super-expensive caps that are likely more snake-oil than actual "sonic gold" in our application.   There was discussion about extending the PCB length all the way down to the base of the mic to facilitate easier mounting of the AMI or Cinemag transformer, but recent tests of the clone against vintage original early type C12 leave the question open about whether the larger core early-style transformer may be a better performing setup overall.  Inquiries to Oliver at AMI about possible development of such a reproduction transformer have gone unanswered so far, but I can try Cinemag and other capable transformer specialists to see.  Anyways, the short story is I would like to leave enough space at the bottom of the mic for the larger core transformer should that ever become available.

There was also discussion about printing a dedicated ELA M251 board, but after some thought, Matador figured the changes necessary to the build are trivial enough that we really don't need a new board. . . as originally stated. . . even though he did lay out a board.  So, we will most likely proceed with a detailed build guide on the current PCB for the ELA preamp circuit.  Note:  9 position pattern switching of the C12 will be retained in our build so this will be a hybrid setup.  Sonically, in theory, it should not make a difference how the capsule is polarized.  Benefits are obviously more pattern options, easier build as we retain OEM physical configuration, and the ability to use capsules that do not have isolated backplates (most available options do not have this!).

Prototypes of the 2nd Generation GT-2B and SYT-5 bodies are moving forward.  The latest word is that the factory has completed "some" samples for me.  I presume this is at least the final revision SYT-5 prototype but could very well be both SYT-5 and GT-2B prototypes along with 2nd revision HT-11A headbaskets to incorporate a slight bend in the hoop base for cleaner lines (as originally spec'd but not executed correctly by the first-run factory).  I am again, cautiously optimistic.  A few photos will confirm if we are on-track or stalled again.  There is a Chinese holiday until the 7th (that would be today) so I would think I should hear something around the 10th.  Stay tuned here for updates.

New products are in the pipeline:

1.  "prototyping" pcb set for the HT-11A microphone.  This board is similar to the C12 PCB set but has no traces except for the tube heater supply voltage.  Teflon standoffs in press-fit configuration at the top of the mic will allow for traditional turret-board style wiring of C12, ELA M251, or any number of other mic configurations desired.  For those who would like to experiment with a point-to-point type tube mic build, this is a clean platform to do so in the HT-11A body with minimal fabrication and fitting of parts.

2.  Fully regulated psu board. . . most build problems we have encountered revolve around the passive B+ voltage supply of the current psu design.  The fully regulated design will allow for larger range of voltage adjustment and easier build.  With Matador's attention to the technical details, I am confident this will be clean and noise-free option.  We will of course test it head to head against the existing passive B+ type psu to confirm that it runs without issue.  Wider adjustment range should allow this psu to be used for more microphone types without adjusting passive components.

3.  Switch mode power supply adjunct pcb for U87 AI type circuit to use in conjunction with poctop's DU87 PCB's.

Can you elaborate on the big core transformer? It sounds like you're saying the larger core original C12 sounded better. What was better? Bigger bass?

HT-11A revision - will this include a dampened headbasket to get rid of ring? You said cautiously optimistic, but since I am still waiting on my CT12, I could stand to wait for the revision headbasket, possibly.

C12 point-to-point board - Any timeframe at all, or potential price?

Will it still be possible to get the older C12 PSU board? I just want the closest to original c12 as possible.

Thanks!

I put Cinemag transformer inside of the transformer case that came with the microphone, and I feel that this option should be preserved for future iterations. Seems more eloquent than using ties, IMHO....

Also, regarding the new board, there is probably no reason to have traces for the heaters on the boards. Simply run twisted cables right up to the tube. Keeping the high current heater leads off the board makes sense, at least theoretically.

Finally, I'm glad to see that the teflon standoffs will be press fit. I modified the current boards to isolate the high impedence part of the circuit from the board, and the difference in sound is subtle, but real. The modifed mic seems to have slightly more body/bass. The mic now sounds more [insert your favorite audiophool superlative here].

Thanks again for your great work!

It's about 60 mils longer than the original.  The teflon standoffs are designed for the Keystone 11308 teflon turret.

Other than the heaters, there are no pre-defined connections.  You get to build whatever you want however you want it!

That being said, yes, if we find any keepers from a prototyping setup I'll be happy to post (and I'm sure Chunger will awesomely document) wiring diagrams using the prototype board.

Should sound fantastic!  The C12 circuit is essentially flat so you'll get whatever the capsule gives you (no Neumann de-emphasis or Telefunken filtering, etc).

Not that I have seen.

I'm guessing people building C12's aren't looking for that kind of sound.  C12 has a very wide response with a response peak way up in the stratosphere (like 10kHz).  It gives it a very "airy" and "hi-fi" sound with little midrange emphasis.

This is the opposite to the 47 type response, which has a midband peak from 500 up to 4-5K range.  Everything below and above this is flat to slightly down (as compared to the C12).  It's a totally different spotlight on the sound.

Exactly. I don't care too much for the CT-12 capsule. It is a fantastic capsule, just not for me.

I like the sound of U47's, U67's and M49's. But the projects for them are way more complex and expensive.

The reason why this c12 build is interesting, is because it is very easy to build, and the instructions are very nice. Almost like Lego. I like that ;) The PSU-pcb comes with it, A BIG PLUS, and the tube used is way more ready available than say, ac701 and VF14.

This is why I am thinking in the c12-circuit with m7 capsule route.. Maybe it would turn out to be a very, very nice and allround mic. Maybe even better and more allround than some of the "classics"..? 8)

JJ Audio made a mic I believe it was their "Dutch" model which is very similar circuit to this C12 project and used an M7 capsule.  I remember being thoroughly impressed with the audio clips posted on that combination.  Truth be told, my engineer prefers the Neumann-ish sound much more in practical use, and I have a Beesneez M7 that I plan to try in this circuit once I have completed all of the obligatory and relevant  "proper" C12 tests that I need to do.

AHAAA!  My internet-fu is strong today.  I found the Gearslutz post.  This is a JJ Audio modded Apex 460 with Thiersch blue PVC capsule.  http://www.gearslutz.com/board/5977942-post38.html (http://www.gearslutz.com/board/5977942-post38.html)

There seems to be a ton of interest right now in the ELA M251 that by design was supposed to be Telefunken's answer to the NEumann studio mics. . . the circuit seems to try and tame the inherent treble spikes and such.  I suspect a lot of people would be well served to simply try a neumann-type capsule in this nice flat-response circuit.

Thank you

Matador may be able to give better guidance on this because I am not the most technically versed person, but:

1.  PSU. . . ours is a full wave rectified setup with better filtering and superior components.  Cleaner/more robust in every way.  Bias voltage is handled identical to original C12.

2.  PCB quality is superior in materials and layout.  When cleanly assembled, sonic performance of the preamp circuit is uncompromising.

3.  Component choices. . . it is notoriously difficult to find parts that fit in the stock HT-11A layout. . . there is much more flexibility with our PCB for experimenting with different caps, etc.

4.  Yellow colored PCB's sound at least 37% more awesome than other PCB colors in blind test studies.  It is an undisputed fact  ;D

That being said, the stock Alctron HT-11A is one of the most popular modding platforms in existence and there is a TON of information available online detailing various ways to do it.  There are also many semi-custom mic companies that offer turn-key products that start out as Alctron HT-11A's in one form or another.

Hi Guys,

The mic in question was a Apex 460 with an EF95 (6ak5w) The transformer was a 2461 NiCo transformer from Cinemag. The capsule was a Theirsch M7. The EF95 works well with this transformer. I used a Russian PIO capacitor.

I have used the Theirsch M7 capsule in a modified 251 style circuit (6072a) with amazing results.

When I set up the C12 negative bias to the grid , I use a trim pot and tune the mic and capsule for the best tone.

Hi Jandoste,

I just looked at your invoice and the PCB was not ordered. . .  I have logged in webstore and paypal

2x silver teflon hookup wire
1x HT-11A type 1
1x 35mm K67 capsule
1x C12 parts kit with 1uF cap and T14

The parts kit does NOT include the PCB.  These items are listed separately because many builders prefer to source their own electronic components for projects.  Please note the following text in the webstore product description:

"Please note, the item is for the electronic components only. The PCB needs to be purchased separately here (link provided). We are pleased to offer AMI's outstanding T14 reproduction output transformer as an option for this kit."

I apologize for the confusion.  I strengthened the language in the product description when this mistake was made in the 1st batch of parts kits.

UPDATE:

We are now on revision 1.2 of the C12 pcb set.  Only the slightest of changes was implemented on the revision.  The board was lengthened by .060" to give slightly more length to the output capacitor slot.  The V-cap 250V 1uF OIMP type capacitor now fits without mods.  Since the kit-supplied Erse units have been working superbly in stock .56uF and 1uF options, I have not had a chance to test these super-expensive caps that are likely more snake-oil than actual "sonic gold" in our application.   There was discussion about extending the PCB length all the way down to the base of the mic to facilitate easier mounting of the AMI or Cinemag transformer, but recent tests of the clone against vintage original early type C12 leave the question open about whether the larger core early-style transformer may be a better performing setup overall.  Inquiries to Oliver at AMI about possible development of such a reproduction transformer have gone unanswered so far, but I can try Cinemag and other capable transformer specialists to see.  Anyways, the short story is I would like to leave enough space at the bottom of the mic for the larger core transformer should that ever become available.

There was also discussion about printing a dedicated ELA M251 board, but after some thought, Matador figured the changes necessary to the build are trivial enough that we really don't need a new board. . . as originally stated. . . even though he did lay out a board.  So, we will most likely proceed with a detailed build guide on the current PCB for the ELA preamp circuit.  Note:  9 position pattern switching of the C12 will be retained in our build so this will be a hybrid setup.  Sonically, in theory, it should not make a difference how the capsule is polarized.  Benefits are obviously more pattern options, easier build as we retain OEM physical configuration, and the ability to use capsules that do not have isolated backplates (most available options do not have this!).

Prototypes of the 2nd Generation GT-2B and SYT-5 bodies are moving forward.  The latest word is that the factory has completed "some" samples for me.  I presume this is at least the final revision SYT-5 prototype but could very well be both SYT-5 and GT-2B prototypes along with 2nd revision HT-11A headbaskets to incorporate a slight bend in the hoop base for cleaner lines (as originally spec'd but not executed correctly by the first-run factory).  I am again, cautiously optimistic.  A few photos will confirm if we are on-track or stalled again.  There is a Chinese holiday until the 7th (that would be today) so I would think I should hear something around the 10th.  Stay tuned here for updates.

New products are in the pipeline:

1.  "prototyping" pcb set for the HT-11A microphone.  This board is similar to the C12 PCB set but has no traces except for the tube heater supply voltage.  Teflon standoffs in press-fit configuration at the top of the mic will allow for traditional turret-board style wiring of C12, ELA M251, or any number of other mic configurations desired.  For those who would like to experiment with a point-to-point type tube mic build, this is a clean platform to do so in the HT-11A body with minimal fabrication and fitting of parts.

2.  Fully regulated psu board. . . most build problems we have encountered revolve around the passive B+ voltage supply of the current psu design.  The fully regulated design will allow for larger range of voltage adjustment and easier build.  With Matador's attention to the technical details, I am confident this will be clean and noise-free option.  We will of course test it head to head against the existing passive B+ type psu to confirm that it runs without issue.  Wider adjustment range should allow this psu to be used for more microphone types without adjusting passive components.

3.  Switch mode power supply adjunct pcb for U87 AI type circuit to use in conjunction with poctop's DU87 PCB's.

Can you elaborate on the big core transformer? It sounds like you're saying the larger core original C12 sounded better. What was better? Bigger bass?

HT-11A revision - will this include a dampened headbasket to get rid of ring? You said cautiously optimistic, but since I am still waiting on my CT12, I could stand to wait for the revision headbasket, possibly.

C12 point-to-point board - Any timeframe at all, or potential price?

Will it still be possible to get the older C12 PSU board? I just want the closest to original c12 as possible.

Thanks!
Chunger, would you mind addressing these questions? I don't think they've gotten answered yet, but maybe I missed it. Thanks!
Title: Re: Unmarked Donor Microphones, C12 Kit, and Associated Parts from the Motherland
Post by: chunger on October 30, 2013, 01:14:37 AM
I've asked the new headbasket be either glued at around the perimeter at the factory or spot soldered all the way around.  Either solution will resolve the "ringing" problem some have experienced.  For now, adhesive seems to solve the problem on current production units.

Both C12 pcb's and point-to-point or "proto" microphone pcb's are now available on the webstore.  The revision 1.2A boards only changed the length a little bit.  If you opt to install the transformer inside the original metal bell cap, you can still do so.

UPDATE:  My samples were damaged in the flooding. . . they are being re-made.  I am informed 2 of the 3 "project" prototypes have already been complete.  These are:

2nd gen GT-2B
2nd gen SYT-5
custom headbaskets for HT-11A (new factory, same tooling because previous factory was leaking the design to other vendors)

I don't know which ones.  My factory rep has let me know they will try to get product in my hands in December.  That is the first "firm" timeframe or at least target timeframe I have heard so I am passing that along if folks are planning ahead.

Good, bad, and no news from the factory. . .

It looks like they are not nearly as far along as they let on in my last communications.  I receive a few pictures of some components in progress for the gen 2 GT-2B. . . factory was moving in the wrong direction with some of the parts, so I've had a flurry of emails back and forth. 

I guess in a way, I am glad they sent preliminary photos because otherwise, I would not have known I need to make more detailed models and dimensioned drawings.  Usually, if the factory has a certain "standard" way they like to make things, it's easier to let them iron out the fine details, but they were about to make the internal rail system wrong and that would have jeopardized a lot of subsequent things.  So, I've had my head in the computer screen furiously modeling.  I'm not particularly expert at CAD, so it's a best effort sort of deal.

(http://studio939.zenfolio.com/img/s10/v100/p800700975-4.jpg)

gen 2 SYT-5 is much closer because essentially all I asked them to do is change the headbasket mesh material from the prototype.  But, I have not seen a photo of the actual headbasket with the actual mesh, so I am hoping it's not vapor.  My rep tells me they are making tooling for bending and drilling the frame rails for mass production (the previous sample had rails made from machined brass for function verification).  All I need is to see a picture of the new mesh material on the gen2 SYT-5 body and I will immediately pull the trigger on a large production run.

The GT-2B may lag a little bit behind, but I will not wait for both models to be finalized to start making SYT-5 and make a cargo shipment to me.  If only the SYT-5 is ready to roll, I will take delivery of that model immediately.  I know many people have been waiting a long time for these.

The latest photo provided by the Chinese factory for SYT-5 gen 2 headbasket had updated mesh materials, but outer layer was diagonal (45 degrees) instead of straight (90 degrees).  I have requested a corrected sample.  I will not move forward with production until I see the mesh is executed correctly with correct materials.  Sometimes dealing with a busy factory can be infuriating.

Hey Chunger.  Are you planning to or able to get the u47 style power supplies like mica dome is offering?  Also was curious if your upcoming pcb would be usable with the io audio kit.  Obviously the 105v would be easy enough to dial in but what about pattern and bias? 

Really looking forward to seeing the gt-2b finalized and in stock!

Are you talking about the larger Alctron PSU? 

(http://studio939.zenfolio.com/img/s8/v78/p1396522388-4.jpg)

I have looked into it.  I can get them, but have not had time to work with Matador and develop any plan and PCB to execute the original U47 105V PSU inside that case.  I am fairly sure the box dimensions are big enough to hold everything, but Dan's cases have been working well so far for everyone to this point.  Also, the price was not as favorable as I would like to make it a "no brainer".

As for the upcoming regulated PSU, I am fairly certain it can be tweaked to provide 105V B+, but the question is if the stock Chinese power transformer can handle the load as the heater is also supplied by the B+ in U47.  With such a small package in the "normal" smaller psu case it is difficult (pretty much impossible) to swap a large part like a transformer.  I have not been able to get specs for the transformer used from the microphone OEM companies.  If I dig deeper and locate the source for the part, I may be able to buy a batch spec'd to different voltage that would be suitable for the application.  We will have to test the transformer to see where its limits are.

Movement on the STY-5 mic bodies.  I've told the factory to prepare to make a large production run of bodies to put a fire under them to get that headbasket right. . . aaaaannnnnnd. . . it's inside out, but I think we have the right materials happening here according to the sample that I sent.  And, the factory is being responsive. . . the previous sample was not inside out, but the outside was at a 45 degree orientation instead of straight.  Frustrating, but we are moving forward and now it is clear they are using a proper 3 layer material setup.

(http://studio939.zenfolio.com/img/s1/v56/p968719374-5.jpg)

Once I see a correct headbasket photo, I pull the trigger and we go into production run.  They will also mail me the sample for final verification, but that usually only takes 2 days from China to me by air so that will be quick.  There should be plenty of available units for everyone who wants one and remain in stock for some time.  This will be a really big order.

Per my request, the base has been modified to expose more thread and we will be using an M24 threaded shock mount.

Hi chunger, I have a few questions :

- Concerning the gen 2 GT-2B, will the Cinemag CM-13101 fit better inside ? If so, the gen2 is closer too the original 47fet in size (bigger) ?

- On the gen 2 STY-5 what are the differences ? Closer matching headbasket ?

Thanks in advance for your answers !  :)

The spec sheet says the CM-13101 is 39mm wide. . . the gen 2 GT2B body has 49mm inside diameter at the base (including the rails, so it should fit.  I will have to go back and measure poctop's PCB length to verify if there is space at the bottom for the transformer, but from what I remember with the AMI T49 adapter board and transformer orientation, it should fit.  This is a 60mm tube, so it is the best case scenario when it comes to fitting things inside.

You should be able to just retrofit the 1st gen syt5 with a gen2 headbasket and the rest of the cosmetic differences will be quite minor.  The gt2b however will be a different microphone altogether.

I've been a CAD monkey lately working on the GT-2B body.  The Chinese factory doesn't seem to be "getting it" on this mic for some reason.  Construction methodology is not what this particular factory likes.  I am pushing to finish my full set of dimensioned drawings for it and then submitting it to a shop here in the US to prototype.  Then, send prototype to China.  At any rate. . .

Here's me trying to account for all the various capsule mounting schemes.  Beesneez uses 2 screws aligned front/back.  The "normal" rubber chinese mount uses 2 screws aligned side to side same spacing.  Theirsch uses a center screw hole.  My plastic "domed" mounts require threaded M2 holes oriented side to side but wider along with wire pass-through holes going through the domed section.  I think this should allow mounting of darn near any capsule mount though.

(http://studio939.zenfolio.com/img/s5/v124/p881085737-4.jpg)

Threads and intersecting curved geometries are kindof a pain in Sketchup, but we're learning.  These are not "true" threads.  Just horizontal ridges.  Next time I'll figure out how to coil like real screw threads.  This was good enough to get the point across.  Can't use the Sketchup files for tool paths anyways.

Hi Chunger

...while you're on capsule mounting options:

I am in the process of ordering a Thiersch Blue Line Capsule and am wondering which capsule holder height to order to suit the upcoming GT-2B bodies?

I guess it would be good to get the capsule at the correct U47 height...

Thiersch offers 3 different heights for their STS 7 Capsule holders:

STS 7 a - 58mm
STS 7 b - 55mm
STS 7 c - 52mm

I assume these heights are referring to the top of the capsule...

From what I can gather the U47 had a capsule centre 45mm above the mounting plate...in this case the 58mm mount seems correct.

How does the GT-2B headbasket/Mounting plate relative heights/dimensions match up to the original? Will the 58mm mount to give a 45mm centre be correct here too?

A spacer can always be easily constructed if the capsule is too low, but I don't want to go too high!

Thanks.

Regards

Wayne.

2nd gen gt-2b will fit the mk47 kit. . . I dont know if you noticed but it even has threades screw holes specified for the chassis mounted resistor in the build so no drilling.

If only the factory in China were as with it as you are Chunger!  Thx for the update.

Hello there,

Just a silly idea I had when looking at some U47FET pictures.

Since you're doing what looks like a complete overhaul of the GT-2B design, why not include a swivel arm too ?

Or maybe just a screwing thread hole ?

I'm aware that it would make it more expensive and need a lot of more work from you on your CAD but it would look awesome.

Thanks,
Steph.

PS : it's not really clear to me, are you also designing a new headbasket too ? More "U47 like".

PS : it's not really clear to me, are you also designing a new headbasket too ? More "U47 like".

The headbasket will be as exact as I can reasonably get to the original U47 dimensions.  It was a bit of a juggling match for dimensions.  In looking at the original U47FET, it seems they are using a casting for the body that integrates the side lug where the swivel mount attaches as well as an offset XLR connector at the base with a recessed switch.  Cost if implemented might escalate dramatically if I attempt this.

The other consideration on my part is ioaudio's mk47 kit that I felt was a really nice, streamlined package in the original GT-2B.  No space wasted.  I wanted to retain that internal feel.  Plus, if I continue on the current development path, it is an easy thing to make longer frame rails and a longer tube and create a  "short U47" offering that more closely tracks that vintage look.

In order to accomodate the current PCB's and associated transformers, i was not able to make the proportions short enough to track exactly with the U47FET though I am close.

Comes down to cost I guess.  On it's own merits, and based on final price, It think this will be a solid option for current designs and for people to adapt new projects to the "native" internal frame structure.  From this point, having hit the major design criteria, I'm seeking the path of least resistance to making it actually happen which is sharing the same M24 screw type shock mount as the gen 2 SYT-5 and making the tube simple and easy to manufacture.

Update on gen 2 SYT-5.  The factory continues to frustrate me, but we are getting closer logistically to our large production run.  Our final pricing is not as favorable as originally quoted to me by a large margin, so it does not look like I will be able to reduce cost any significant amount at least upon this initial production run.  I may be able to find some streamlining processes in subsequent runs, but for now, my priority is to get bodies in my hands as fast as reasonably possible.

So, after 2 samples, we appear to have the correct materials and 2 out of the 3 layers oriented properly. . .the outside and the inside.  Our middle layer in the latest sample is at 90 degrees instead of the correct 45 degrees.  I will take delivery of this sample to confirm that the materials used are indeed the same specification as the samples that I sent to the factory.

(http://studio939.zenfolio.com/img/s10/v108/p400430547-4.jpg)

(http://studio939.zenfolio.com/img/s10/v108/p176364084-5.jpg)

In order to show good faith in our dealings and not perpetually be the "overly-picky customer". . . I plan to move forward transfer the initial payment for the production run once I verify the materials are correct.  I have instructed my Chinese associate to confirm a change in our price agreement to reflect a discount if that center mesh layer is not adjusted to a 45 degree orientation in the production run.  I need to have that caveat official before moving forward with such a large deposit.  This moves the ball forward while still maintaining my insistence that the mesh layers must be executed exactly to specification.  But, we have a worst case scenario right now of the center mesh being 90 degrees.  Taking a step back, and looking at the project as a whole, it would not be the end of the world being as our external dimensions are significantly different from the vintage original sample anyways.

Due to the increased cost over my previous projections, I will not be able to make cases and other periphery accessories just yet.  I felt it was important to maintain my very large order quantity even with the higher cost per unit to show that this is a serious endeavor to the factory and to make it a priority.  We will see if the quality of this production is much better than the 1st gen bodies.  It should be given the other companies this factory OEM's for.

Another small development is I have located a producer of power transformers in the footprint that fits inside the popular Chinese PSU enclosures.  Matador seems to be in some sort of switch mode power supply development obsession so I felt it would be beneficial from an ease of build perspective to continue re-using our readily available and low-cost PSU enclosure.  The 12V power transformer will allow for a variety of voltages to be generated from his switch mode supply modules both + and -.  We should be able to make a nice, low-cost, compact 51X power supply for instance.

(http://studio939.zenfolio.com/img/s5/v124/p234287990-4.jpg)

The 90V power transformer is targeted directly at adapting our existing passive B+ power supply PCB for use in the U47 type builds and generate a well filtered 105V B+ without producing the extreme heat the original topology generates.  I would need to consult with Matador to see if this same 90V transformer can be used in the upcoming regulated PCB as some theories point towards regulated supplies being quieter for high current applications (ie. where the heater supply is tapped off of the B+ as in U47).

Just had a nice conversation with Dave over at Cinemag regarding a large-core offering at 12:1 ratio suitable for the C12 kit.  This is the primary reason I did not extend the PCB for easier transformer mounting in our current revision 1.2.

It looks like he is willing and able to make the transformer for us.  Being as I do not have original samples in my hands, I do not think this will be as exact of a "vintage reproduction" unit as the AMI T14 is for the smaller late style transformers, but sonically, it will yield the overall characteristics of the larger core particularly in the bass response, and I have always been impressed with Cinemag's level of quality and development in their transformers.

More to come.

For now, CM-13114 is being spec'd in the budget kits and the cost reduced as appropriate.  Also,

CM-13114 (12:1)
CM-13113 (9.5:1)
CM-13101 (9.1:1 large core)

are being offering in the webstore.

Can we talk some more about this transformer situation? The first transformer in the C12 was the Hiller, then the Henry Radio, and then the small Haufe. While Oliver's T14 is the smaller size of the Haufe, it is sonically modeled after the flatter Hiller.

What overall characteristics of the larger core are you looking for? I could seriously not imagine my C12 having any more bass than it does haha. It's bassier than my U47

micaddict,

I just meant that the AMI T14 was a smaller form factor, not that it was dimensionally the exact same as Haufe.

Here's a quote from Klaus:
"From my upcoming book "The Vintage Microphone Handbook":

"Three distinct generations of C12 can be identified, primarily by their visibly differing output transformers. The first one, from 1953 to about 1955, used the Hiller-made T14. A beefy looking affair, which, as mounted on the mic’s frame, barely clears the housing tube.

The next generation C12, including most ‘Siemens SM 204/23’-branded models, used the Henry Radio, model 2148, identified by that number on one side, and a black diamond painted on the opposite side onto lacquer-soaked brown cloth wrapping. These transformers can be found as early as 1954. Around 1958 the mic received its final transformer, the rather anemic looking T14/1, made by Haufe, near Frankfurt, Germany- the only transformer company that has been continuously supplying German mic manufacturers since post-war years through today. The last transformer version, by the way, was also used in AKG’s C24, ELA M 250/251, and C28A mic models." © Klaus Heyne, 2013 "

Nice. The internet remembers better than the memory :p.

Also from that pic I would wager the AMI T14 is a little bigger than the Haufe, but smaller than the Henry. Regardless, I'm still curious about chunger's comment son the low end. I would actually be curious how to DECREASE the bass in my C12.

You could Use a smaller value grid resistor as used on the Ela-m-251 which uses a 30M to create a bass cut.
I tried recently in my 251 Build and it sounds great with my TC capsule but rubbish with the Chinese ck12 types

Waiting for tskguy 's production batch of HK12 capsules in order for premium kits to be available.  I'm not going to rush him in any way on development because I would like above all for these capsules to be perfect.


UPADTE:

Production of the Gen. 2 SYT-5 bodies has begun.  I submitted a manufacturing deposit for a very large order of these.  I am tightly monitoring progress on these particularly the headbasket mesh configuration that I have been trying to get the factory to make correctly.  The new factory understands that these are a high priority and we hope to complete these soon.

We are out of stock on HT-11A bodies for the C12 and ELA M251 clone builds.  A follow up order was placed more than 2 months ago, but the supplying factory has had some delays.  They are usually very timely.  We should see these back in stock late February.  I am following up on an option to streamline these bodies to NOT include the complete microphone, case, and other auxiliary parts that we do not absolutely need for the kit.  This would reduce donor body cost as well as decrease overseas shipping significantly.  If this is an attractive proposition, please let me know.

C12 parts kits have been modified to include the required parts to run the alternate 12AT7 tube as well as the original 6072A tube.  I have also acquired a supply of NOS Mullard 12AT7 tubes and will be making these available on the webstore.  I have also obtained a quantity of NOS 6072A tubes 50's, 60's, and 70's.  Per my belief that microphone grade samples of these tubes should be preserved and paired with premium capsules (ie, Eric's new HK12 or Tim Campbell's CT12), I will only be selling NOS 6072A tubes in premium kits (not loose).

My entire family seems to have gotten sick over the holidays which has incurred delays in shipping.  I hope to catch up soon, but in the meantime, I apologize for the delays getting orders shipped out.  We are still steadily shipping but running about 10-12 days behind.  Thanks for your continued support.

Hey hey. . . delays may have been to our advantage in donor microphone land.

I've negotiated parts only for the upcoming batch of mics which should bring costs down a good chunk and reduce wasted materials.

- HT-11A's will come with stripped body, choice of custom headbasket style (type 1, type 2, type 3), shock mount, and wood box
- PSU's will be available as a separate item in anticipation of many PSU options Matador is developing for the platform
- Chinese 7 pin XLR cables will be available as separate item (many people opt to upgrade to Gotham, Mogami, or other premium cable so why not save a few more dollars while we're streamlining)

- since the stripped body costs were very favorable, I am bringing in some 1st Gen GT-2B bodies because the price will be really nice for DIY and there are a lot of PCB kits that utilize this body.  I will continue development on the 2nd Gen GT-2B bodies, but those will be considerably more expensive to produce so I think I will continue to offer 1st Gen GT-2B as a great budget option as long as the relationship with this supplier continues to improve!

- 2nd gen. SYT-5 bodies are in production as mentioned before with our new factory partner.  These should be fantastic with updated 3 layer headbasket meshing ,and we are bringing in a huge shipment of them this time around.

We are bringing in 2x the number of HT-11A donor bodies than previous shipments and 3x SYT-5's.  I am trying my best to make sure these items stay in stock this time around.  Thanks for your continued support, and I hope to have more exciting news soon.

Awesome! Please also consider stocking the screw on shockmounts that came with the 1st gen of GT-2B... they were really nice (also worked with 1st gen SYT-5s) and I haven't been able to find another place to get them.

The stripped bodies should be in late February.  The shockmounts will be updated screw-type as opposed to the normal pinch type we have been using so far.  I believe they are marginally larger than the current ones and are "spider" type suspension.  Pricing will depend on final logistics costs as well as confirmation of our negotiated prices, but ballpark. . .

Body and shock mount - $75
Power Supply - $56
Wood Box - $14
OEM 7 pin cable - $25

These items will be broken up and ordered separately so for example, if you already have a case and plan to use a premium Gotham cable, you just order the body kit and power supply spend $131 and save $39 on your project.

I have not been a fan of the plastic box due to the fragile hinge style and the tendency for the area of foam between the psu and the cables to become damaged during transit.  Also, I believe shipping will be less expensive without the black box as long as the wood box can fit inside a USPS medium flat rate box.  We will see.  I just realized that the wholesale price for Apex 460's through distributorship may not be as low as I thought it was so there is a possibility I can supply some of the low-volume semi-custom mic shops in the US.  If that happens, I will likely purchase a few complete mic kits in subsequent shipments.

There are some inexpensive aluminum cases available with modular dividers that have been suggested here on forum that should work better than the Alctron black plastic cases.  Also, I may custom design a case to hold multiple microphones in the future, but I am very extended on this China order as I have increased my quantities to nearly ridiculous in order to negotiate parts sales from the factory, so I don't think I can stretch much more.  As it is, the wife will probably hang me for the total cost of the shipment!

I have not been a fan of the plastic box due to the fragile hinge style and the tendency for the area of foam between the psu and the cables to become damaged during transit.  Also, I believe shipping will be less expensive without the black box as long as the wood box can fit inside a USPS medium flat rate box.  We will see.  I just realized that the wholesale price for Apex 460's through distributorship may not be as low as I thought it was so there is a possibility I can supply some of the low-volume semi-custom mic shops in the US.  If that happens, I will likely purchase a few complete mic kits in subsequent shipments.

There are some inexpensive aluminum cases available with modular dividers that have been suggested here on forum that should work better than the Alctron black plastic cases.  Also, I may custom design a case to hold multiple microphones in the future, but I am very extended on this China order as I have increased my quantities to nearly ridiculous in order to negotiate parts sales from the factory, so I don't think I can stretch much more.  As it is, the wife will probably hang me for the total cost of the shipment!

Those aluminum cases are expensive here in Europe, my wife can customize the plastic boxes easily with custom pockets inside and outside for the cables and other accessories. So if you will keep some cases in stock I'll order them.

UPDATE:  manufacturing has indeed begun on the gen 2 SYT-5 bodies.  I know a lot of folks have been waiting a long time for these, but I have emphasized to the factory that my #1 concern is the quality of the build.  Yes, we want them quickly, but we would much rather wait if they cannot complete the entire production run before the new years festival shuts everything down.

If indeed there are no reasonably priced case solutions available to the European market, I will look into having cases manufactured to a custom spec.  Reducing the shipping cost for these donor microphones is a priority for me, and with the wood box solution, it may be possible to reduce the average shipping to European customers by about $30 which is pretty significant.  Another alternative would be to start importing to a European based distributor.  None of these ideas are very concrete. . . just running some numbers to see if it is feasible at the volumes I'm currently ordering.  I would also have to learn all of the overhead costs involved in import of cargo shipments to Europe.  I'm just starting to figure everything out for the US.  We shall see!

I'm surprised there is not a "european" Harbor Freight Tools equivalent that imports low-cost tool items from China.

Just got confirmation that the new ht-11a microphone shipment will be parts only as requested with upgraded shock mount and wood box.  This should result in savings for both the donor mic and shipping costs.  I also increased the total units ordered by 2.5x so they should remain in stock longer than last time.

Yes there are similar items here, but they are more expensive than in the US. I can order from UK, or from Germany, but with the high shipping costs it doesn't worth it.

Hi Olle,

There is no wait list.  There should be enough in stock of all types to last at least a few months.  I think everyone who wants one should be easily accommodated.  If there is a weak link as far as number of mics it will be the 1st Gen. GT-2B donor bodies.  Because I am actively developing the gen 2 bodies and quite honestly because I ran out of funds, I ordered fewer of that type than the rest.

Just a warning...
Although the case you mentioned may be fine, I once had a bad experience with an 'aluminium' case.
The case I once bought looked like an aluminium case, but after a closer look I discovered that it was just metalized plastic, glued on thin plywood.
And what was worse: the plastic layer soon came loose!

Hi Spencer,

As of right now, I have arranged for a parts order at high volume for this batch.  So, I will not have complete microphones.  Power supplies however will be complete.  I didn't want to push the issue of buying them with just the primaries wired in.  The OEM has some q/c methods for their psu's and I want at least that level of verification.

Right now, I am wayyyy over extended on this combined shipment and negotiations with the factory were not easy so I do not want to rock the boat.  But please let me know what you want.  If I continue to get requests from individuals and small scale manufacturers for complete mic kits, I can work on continuing to stock those.  For now, I apologize for the changes.  For the kit builder and customers not in the US, this should be very good because we reduce e-waste and shave some cost.

Will the mike come with the Alctron Transformer as it sounds great in the mike I modded. I used the Fox Mini-Mod with the Microphone parts capsule.

Email me and I can arrange something.  I pulled out at least 3 sets of stock "guts" when doing demonstration and prototyping builds.  I can give you those and you would be good to go.  I'm very sure other probably have those in their spare parts bins now too.

So many have expressed frustration with the passive PSU design and finding correct operating points for various tubes, etc:  so I've designed a fully regulated PSU (with true fixed bias!) that should behave across tube and bias changes.  It's essentially a triple high-voltage linear supply, with the common transformer -> rectifier -> caps -> linear adjustable regulator scheme.  It's designed to work with the stock Alctron transformer and fit into the stock Alctron PSU case.

You just dial in 120V and -1V, and you'll get that, even as the tube ages, or you even switch to a completely different tube.  Noise/performance should be comparable to the stock design, however since the output impedance is very small (compared to the passive design), the sound probably will change in subtle (and hotly debatable) ways.

It also has fully isolated PSU rails, so negative heaters are possible!

Poctop recently released an ELA design that utilizes relays. . . So practically speaking, it switches in the mic.  I honestly consider the 9 pattern setup with intermediate steps to be a feature as opposed to a liability in practical use.  I guess it is argued that the ELA's polarizing scheme is more "pure" in each of its 3 patterns but you cannot simply dial in just a hair of "room" as easily as with the 9 pattern.

That being said,  I still fully plan to document the ELA conversion on our standard C12 pcb and psu soon now that I have organized and stocked the parts kits for that configuration. 

There are other pressing items that require testing, organization, and design that are ahead of this, but my inclination is to mod the body to impliment the required 3p3t switch for pattern switching at the mic.

I think a test may be in order to compare direct 3 pattern switching against the 9 pattern polarizing scheme.  The priblem is poctop's layout is so different that it would be very difficult to test with the same components.  And, as I discovered with my floated hiZ testing, variations in critical components make it difficult to make solid conclusions.

To answer myself, The 35mm K67 capsule fits nicely into the tall custom headbasket that Studio 939 offers (for those people not building a C12 into the HT-11A).  I have not tried to fit it inside the shorter headbasket but ASSuming it will fit as well.  Thanks, ChrisP

Here are some teaser pics of the new "Universal" regulated tube power supply:

(http://musicalsparks.com/images/universal_psu/IMG_20140212_092026.jpg)

I blew my last TL783 regulator and forgot to replace my supply of heatsinks, so I can only do limited testing right now.

Heater Supply - tested that I can adjust between 4.7V and about 11.8V.  The maximum is really limited by the 9.5V AC secondaries of the stock Alctron transformer, so if you plan on reusing it it will only do parallel heaters.  I did manage to sustain over 700mA load so this shouldn't be an issue.  Those wanting to do series heaters will need to find a different transformer. 

This heater supply is fully isolated from ground:  hence you can do positive or negative heater supplies by tying one of either sides of H+ or H- to ground.  For stock positive supplies you tie H- to ground, and for negative you tie H+.  This makes this compatible with U47-like projects.

Bias Supply - This is cap coupled from the heater AC supply so it is fully isolated as well.  It is adjustable from 0V down to -2.5V.  If you want more negative adjustment it's a simple resistor change.  I managed to pull over 50mA from this supply so it is more than enough for bias duties.  Unlike the C12 design, this one is fully regulated, so it is a true fixed bias supply.

B+ - this will have to wait until my next Mouser order. ;)  The design is meant to be adjustable from approximately 90V up to about 250V (operation below 120V requires a resistor change). I'm not sure of the VA spec of the 200V secondary on the Alctron PSU, but I would guess this should be good to about 10mA or so, which is enough to drive a few tube gain stages, even for higher current tubes like 12AT7's.  I wanted this to also be compatible with stock CCDA stages so this should be plenty for that purpose.

This B+ supply is also fully regulated, so once set for a target voltage it should stick even with tube swaps.

Not sure.  I should have the rest of the parts by early next week, and soldering/testing should only take a few hours.  Then I need to ship some boards + BOM's to Chunger so he can do his build thread magic.  We also need to get a sample in to the studio so we can evaluate if there are any sonic variations.

It would probably be useful to gauge the interest level someplace (perhaps a new interest thread) before deciding how to proceed.

The recent Alctron order includes 50 units of "loose" power supplies so yes, I envision the power supply being compatible with many other DIY projects and as such, it would be a benefit to the collective community to have a nice, complete kit with thorough build documentation available.  And as usual, everything will be available "a la carte" as well because this is quite a common PSU package.  I am also discussing what values of custom transformers to bring in as a starting point to cover a variety of projects.

First things first though.  Let's see how the PSU performs "in the wild".

SYT-5's still in production. . . no more major news.  The factory is back to business and I will get confirmation of the headbasket meshing when that phase is under way.

New ETA for completion of the updated Alctron order is 40-60 days.  HT-11A, Loose PSU's, and 1st gen GT-2B bodies are included in that order.  Pricing should drop by a significant margin on Alctron donor bodies.

Update:  SYT-5 production had a snag and my associate at the factory demanded the base rings for the headbaskets be re-machined before moving forward with soldering the mesh layers into place.  Factory was reminded that "This is an important client.  Make a good first impression.".  All parts move to plating after those are complete.  I am glad to have eyes on the ground at the factory this time and someone advocating for me who has enough pull to make a move like that.  Efforts to make the order quantities sufficiently large are paying off as we are getting more love from the folks in charge.  I sincerely appreciate the support and patience from the DIY community that has made that possible.  I know it has been a long wait for the gen. 2 SYT-5's and you guys have choices when purchasing bodies.  I am determined to make sure they are higher quality, priced well, and readily available after we get through this tedious development phase.

I do not think this will adversely effect my updated time estimate of mid-April for "in-stock" status.  The Alctron order is the limiting factor on that and it is looking like I will combine the cargo freight.

Also, Cinemag has finally completed a large order of transformers that I have been waiting for.  I know a 2-3 people have had their orders delayed for quite a while waiting for these.  Those orders will be shipping soon.

That is all for now.

Keep your eye on this thread.  The latest updates are posted here.  These are nearing completion at the factory and should be available best guess mid April.

shipping backlog was cleared early this week!  It's been a long time since I've been able to clear the queue.

Hi Chunger and everyone !

Any news concerning the GT-2B V.2 ?

I got sparkles in the eyes when I saw the prototype of U47FET body by AMI, hope yours looks as good if not better !

UPDATE:

I believe we will have to shift our ETA for microphone shipment from China by about 2 weeks.  This is not based on any new information, but I have not received final confirmation from the factories that the order has been completed.  Taking into account a 3-8 day wire transfer processing delay, cargo ship freight time, and customs clearing, I think it is safe to say we will not be seeing product in stock by my previous mid-April estimation.

The next communication I get from the factories should be confirmation that our items are ready.

UPDATE:

Eric Heiserman HK12 capsule development is near completion.  We have a VERY good  prototype up and running on final production metalwork.  The longer than normal development cycle on this capsule is largely due to the requirement to be able to scale up as needed and ensure a "proper" capsule will be available on reasonable lead times for DIY.  Final testing and spec verification now.

(http://studio939.zenfolio.com/img/s6/v140/p535909687-5.jpg)

These will be available in our webstore at best current estimate in about a month. . . likely premium full kits will role out at the same time.

Update on microphone production status:

There is currently a severe smog problem in Shanghai right now, and the government has ordered metal coating facilities to shut down until air improves.  This is causing delays in our production as well as all microphones coming out of China.

$425 - Same pricing as directly from Eric.  I carry the tiniest sliver of a margin on these, but am pretty much just "passing them through" as a service and pre-purchase in bulk to cover development/production costs.  I will get test clips up as soon as I am able to arrange a proper test session.

UPDATE:  Alctron has updated me on the status of our order, and it will be finished before the end of the month.  This means:

- Ht-11A donor mics
- Gt-2B 1st gen donor mics
- loose PSU's

will be coming across the ocean at that time.

Gen 2 SYT-5's are still in development limbo.  It is absolutely infuriating trying to get a 3 layer headbasket mesh correct from the Chinese factory.  All of the frame rails, tubes, headbasket base and hoop pieces are ready.  I need them to show me a correct headbasket to confirm and then they get stamped, soldered together, and off to the plating.  We are 2/3 of the way to the correct configuration.  Hopefully, the next couple days will see a correct sample!

Thanks for your patience.

UPDATE:

Alctron is finished building my order!!   ;D

- GT-2B 1st gen
- HT-11A donor bodies
- loose Alctron PSU units

will be coming my way via cargo ship as soon as my wire transfer clears and my associate in China can arrange a container.  I am not consolidating orders with the SYT-5 microphones because i know many people have been waiting for these parts and the Alctron order by itself is quite large just by itself.  Thank you for your patience.  We should be in stock with all of these units for a good few months at least.  I ordered a lot.

As for the SYT-5's, I had a productive phone conversation with my associate while he was physically at the factory clarifying the details of the gen 2 mesh configuration which the factory has been getting wrong in the last 3 prototypes.  We were able to locate and verify the correct materials IN STOCK at the factory so the next prototype should be spot on.  This is the final hurdle on the SYT-5 development.  All other parts of the microphone are already completed (base cap, frame rails, headbasket base, headbasket hoop, shock mounts).  Once the headbaskets are pressed and soldered in, the whole lot goes to plating all together.  Once the 1st batch is processed through to completion, follow-up orders should be very smooth and I should be able to keep them perpetually in stock if I plan properly.

More news will be posted here no this thread as soon as I receive it!

UPDATE:  ship date for Alctron order will be May 7 via ocean freight.

Also, we have run into a snag with the Alctron order.  The wooden boxes that were produced are not up to Q/C standards so they will have to be re-made.  This will take an additional 25 days.  I am having the rest of the parts shipped separately.  I may be able to combine the ocean freight for the wooden boxes with the SYT-5 microphones.  Obviously this means wooden boxes will not be available for at least another month, but I will be able to ship microphones immediately.

I am also told the new boxes will be coming from a different source factory and will be $2 more per unit which I think is a bit sketchy, but these are the frustrations dealing with Chinese factories.  At least they had the sense to withhold the faulty units instead of just send them out.

Hi, I am looking for 2 of the GT-2B complete microphone kits and rumor goes, there is a shipload full of Alctron coming in ...
Where do I have to put an order, or maybe show my severe interest in buying them ?

I´ve been looking on the studio 939 site as well as in the white market thread, but I seem to be blind - shame on me.
So somebody help me please.

Also interested in 2 of the HT-11A type 2 kits.
Thanks for assistance.

Hello,

Thanks for your interest.  I do not generally post anything for sale until I have product in hand, so you have your eyes in the right places.  I just have not updated the new items to the webstore yet.  Also, I am not taking pre-orders at this time.  I am confident, however, that I have ordered enough of everything to last quite a few months unless something drastic happens beyond the normal surge of orders when donor microphones come in stock.

I will not be carrying the "complete GT-2B" kits anymore.  The new kits are body and shock mount only to reduce cost for DIY.  Power supplies will be available as a separate item.

UPDATE:  A few minor details about the Alctron order from photos sent from the factory.

- HT-11A base caps in this round are not polished nickel plate like last time.  They are bead blasted nickel plate finish.  The headbaskets are still all polished finish.  This is not how I ordered them, but I feel it is a minor detail and the mics still look good this way.

- We have updated (larger) HT-11A shock mounts this time with dual cam-type locking tabs instead of the previous pinch-type mounts.

- internal transformer "bell housings" were not included with the mic bodies.  I know a few people preferred this method of transformer mounting, but I was on a mission to reduce cost.  If enough demand for these comes up, I may order a few.

- it appears wood boxes for the GT-2B type microphones are ok and will be shipping.  It is HT-11A wood boxes that were defective.

- the microphone bodies come with the standard 32mm capsule mount saddles, but no capsules are included.  We do carry 34mm and 35mm capsule mounts for folks who need these, but often, the capsule saddles can be supplied by your capsule vendor of choice at the time of purchase.

Another update:

Apparently, the HT-11A Type 3 headbaskets that I am receiving with this round of orders is ~9mm taller than the last ones which sortof makes the microphone look a bit odd.  This is disconcerting because I was so hoping to push the ELA M251 style clones and I did like the short headbaskets very much in that application.  I will discuss this with the factory and ask why they changed their tooling.  The joys of working with Chinese factories!  Functionally, I don't see much of a difference here.

So, it looks like we may have a Type 4 headbasket available now by accident unless they are willing to take all of these back and use them for another customer order and either correct the tooling or re-make the correct tooling.  All of this messes with the final pricing, so I am glad I did not nail things down in stone yet until I have product in my hands.

One headbasket goes correct, and another one goes wrong  :o !!  I may consolidate all of my headbasket manufacturing to the new factory as I have much tighter controls on the ground there than at Alctron.

Post by: chunger on May 07, 2014, 02:16:55 AM
We'll see what becomes of it.  They may be able to modify the tooling or take back the taller headbaskets and sell to another customer.  For now, I have about 60 more Type III headbaskets still in stock so just order that type.  I can also have new tooling made, but if I were to do that, I think it would be better to make a new body that has the same outside diameter as the original ELA M251 and provision for an onboard pattern switch.

Are the c12 type microphones protected in case one accidentally engages phantom power?.

Thanks for your input in advance and I will be waiting to place orders for 2 c12 complete kits.

*EDIT...I will let Matador explain in more technical terms below...

...most tube mics require their own dedicated power-supply that functions between the preamp and the microphone...in my experience using tube mics with dedicated power-supplies, accidently engaging phantom-power has never been an issue...

Phantom power will enter the PSU, and travel directly to the 7-pin connector and then to the microphone.

The transformer secondary is completely isolated and does not interact with any of the circuits, so there's nowhere for any DC current to flow.

In short:  it won't harm anything.

Post by: chunger on May 15, 2014, 06:15:12 PM
Yes,  I took a step back from the short body U47 because the Chinese factory was having enough trouble getting the gen. 2 SYT-5 body to my spec. and I decided to focus in on one item at a time to get right.

Now that the gen 2 SYT-5 seems to be on track, I can re-visit my short body U47.  I will likely prototype it in the US so the Chinese factory can have a reference sample that is 100% correct.  Once the short body variant is finished, it is a very trivial task to lengthen the frame rails, and body tube to do the mid-length U47 body.  I do not think anyone is doing that version currently. 

I am already well past the point of no return on development for a U47 variant.  It will just take some time to get right.  Once all of the details are ironed out though, I should be able to hit a good price-point and volume to keep them in stock perpetually.

In the meantime, I've been able to procure the 1st Gen GT-2B donor bodies at a very good price so I think I will continue to stock that item for the DIY value.

The GT-2B bodies are on the boat currently, so they should be available quite soon.  PSU casings are still supplied by Dan here on the forum.  http://www.collectivecases.com (http://www.collectivecases.com).  We are currently prototyping a turn-key U47 PSU in collaboration with ioaudio with the aim of releasing a complete, all-inclusive mk47 kit.  I already have the mk47 kits in stock.

Several people on forum have generously contributed time and significant energy towards the project. . . ioaudio, dandeurloo, Matador, and  myself.  If all goes well, hopefully, we will see a few more "GroupDIY Microphone Alliance" releases in the future.

If all goes well, 1 of these samples will go directly to ioaudio in Austria for very exciting product development :)  1 of the samples will go to Matador for very exciting product development, and one of the sample will get photographed for the webstore  ;D

UPDATE:  Alctron shipment is scheduled to land 5/28.  After that, we will have to clear customs and then I will pick up at the warehouse.

SYT-5 microphone production run has been completed.  We are now waiting for small parts (switch pcb standoffs, switches, capsule mounts, XLR inserts, etc.).  When those parts come in, I will receive 3 samples via air mail for verification before the batch goes to cargo freight.  If all goes well, 1 of these samples will go directly to ioaudio in Austria for very exciting product development :)  1 of the samples will go to Matador for very exciting product development, and one of the sample will get photographed for the webstore  ;D


Please tell me that the original Ioaudio u67 transformer and poctop pcb will fit these new bodies! I have been sitting on a set for over a year now waiting eagerly for the release of the new bodies :)

Yes.  A sample of poctop's PCB was sent to China to confirm fit in the development of this body.  That board is guaranteed to fit the frame rails.

UPDATE:  The current shipment from China has been subject to "intensive exam" and is delayed in customs.

SYT-5 samples are in the mail heading my way via air mail.  Everything looks ok according to photos I have received with 3 exceptions:

1) the threaded base piece is much longer than expected because the factory made an alteration to accommodate the new bottom threaded shock mount.  I do not think I will be able to change this as all of the base pieces have already been machined and plated and I do not want to further delay shipment of the microphones.  I will have new base pieces made with shorter threading and make those available as a separate item.

2) the capsule mount that I requested was not used.  My reason for requesting the specific capsule mount was the ease of raising the capsule height with a 3M hex standoff by 8mm to better center the capsule in the headbasket.  The one used in the microphones is the "normal" rubber mount.  I will look into having plexiglass spacers made to raise the rubber-type capsule mount.

3) the figure 8 marking on the tube was rotated 90 degrees.  The aesthetic is actually not bad at all, but it is not the way I specified the markings.  The most important thing though is the pattern markings are in the correct positions with Cardioid in the center position.

Currently, 300 microphone bodies are completed and 100 headbaskets.  Once I confirm frame rail dimensions and that all current PCB's fit inside the new body, we will move quickly to arrange cargo freight for the shipment.

Hi Chung,

Just a question: If us mic builders can't use the base piece (that is what I am gathering?) and you have to have new base pieces made anyway (we will have to wait anyway, which is OK at least for me), couldn't you just have the factory correct the problem? Regardless of the machining and plating for these base pieces, isn't the problem due to the factory not following your spec?

Please clarify.

Cheers,
Chris

The base piece in it's current "longer than expected" configuration is 100% functional and actually looks fine when attached to the threaded shock mount.  The reason I am not pushing further at this point is people have been waiting a VERY long time for these bodies, and I feel obligated to make them available right away as long as all of the function-critical details are ok.

I have pushed this factory through quite a few iterations. .. MANY more than I would have been able to with Alctron particularly on the mesh specifications.  What appear to be very simple specifications or alterations are not easy to get pushed all the way through to the factory floor to get done correctly.  If I press for a fix right now, they may stall me for another month or 3 before I get the part that I really need and who knows what other specifications might get "broken" in the meantime when they forget what the original specs were supposed to be.

So, I've decided to verify all other parameters for now and request the corrected part be manufactured separately.

Thank you.

If there are any issues with the plexiglass spacers for the capsule holder I would be happy to 3D print them for the community out of either nylon or abs.

...I have to commend Chung for his diligence in getting these new bodies tooled up and manufactured...it's no easy task from an entirely different continent...having seen pics of the new SYT-5 body both in and out of the shockmount, while I noticed the base was extended, I assumed it was to allow for a more secure fitment to the new base-mounted shockmount...didn't really appear an issue until you now mentioned it...otherwise the new bodies look excellent...worth the wait!...

Please note, I will get an initial influx of orders and there will likely be delays in shipping.

I am still actively working on the gen 2.  With the problems the factory was having getting the syt5 correct, I decided to tackle the projects one at a time.  In the interim, I got great pricing on the 1st gen mics and feel it will be a great budget diy option even after the gen 2 bodies are available so I plan to keep them in the lineup.

Hi Chung

Congratulations on getting things back in stock! Sounds like it was a huge effort.

I've been sitting on some tubes and capsules for some time to do a C12 and a U47 build and have been watching this thread eagerly. I'm definitely ordering bits from you for the C12 build...but...I have one eye on max's latest U47 project and I'm holding off on an order until I see exactly what he is offering...

My question is are the GT-2B bodies or HT-11A / C12 kits likely to run out of stock in the next week or two? I'd hate to miss out through hesitation...

Thanks in advance.

Hello everyone.  Please note we have a large backlog of orders right now and shipping lead times will have extended delays.  I am also working 20 hour days The my real job to complete an install so I have not had a chance to pack any orders this week.  I apologize for the inconvenience.  Please contact me at any time for a refund prior to shipping if you made any errors or change your mind.

Also, please note I have not had a chance to recalculate my microphone shipping rates from the VERY large and heavy full microphone configurations.  I will refund excess shipping charges when I process orders individually.

Point to point is the fun way to go!  We're basing the PSU kit  on Dan Deurloo's PSU enclosure and I believe he will have all the PCB and parts mounting points pre-drilled.  All it will do is save wiring time and the effort of drilling out enclosures.  Plus a fixed BOM is sometimes helpful.  Matador spec'd the parts very robust.  The B+ should be able to be grounded and the PSU still remain within temperature spec indefinitely.

quick question. what are the advantages of Matador's MK47 PSU disign compared to the classic PSU design that Zayance offers?

The schematics come from IOAudio, so electrically they are very similar.  My changes:

1) More compact: the finished size is 3.6" square
2) I used more compact TO-220 resistors which have MUCH higher power dissipation capabilities.  Those resistors in combination with the Aavid Thermalloy heatsinks (also compact) means that the resistor temps can be managed without active airflow.  The resistors are rated to 20W and the heatsinks are rated at 7.5 degrees C/W.  This means that each resistor can sustain about 10W without overheating indefinitely (e.g. practically shorted to ground).
3) Spec'd the components for both 200VAC (common in tube mike supplies) and 230VAC operation (common everywhere else)
4) It's in a proven sonically-superior yellow color.  ;D

The main reason for the re-design was to make more effective use of the real-estate inside Dan's cases to give builders more options for torroid and other transformer / choke combinations.

No, I do not have the shorter base pieces or capsule spacers available yet.  First priority right now is to get the mics in stock as built.  I will follow up with development on the revision 2.1 and offer update parts as they become available.

UPDATE:

prototyping for mk47 power supply is going well. . . we have integrated some nice features into the scheme like a built-in voltmeter and external trim adjustment.  I will post details in my mk47 build thread here:

Ocean freight arrangements have been made.  I am uncertain if the cargo has gone out in the boat yet, but it should be coming my way any day now.  Usually, it takes about 2-4 weeks for cargo to arrive and then customs clearing time varies.  My recent 2 shipments have undergone some sort of heightened examination which adds time.  This shipment will include:

SYT-5 microphone bodies
SYT-5 shockmounts
HT-11A wood boxes
60mm diameter (U47) shock mounts.
misc. electronic components (switches, XLR inserts, etc.)

Thanks Chunger!...can you verify if there is enough exposed thread at the base of the original SYT-5 bodies to make use of this new threaded shockmount?...

Post by: bancho on July 23, 2014, 11:13:06 AM
thats great chunger!
about the 60 mm shockmount... how is the mic mounted in this shockmount? same as SYT-5 shockmount or like original/Flea has?
Title: Re: Unmarked Donor Microphones, C12 Kit, and Associated Parts from the Motherland
Post by: chunger on July 23, 2014, 02:49:55 PM
the 60mm shockmount is a dual ring attachment with flip-style tension tabs.  Similar to the way the Flea mount works, but different dimensions on the exterior of the mount and the finish/build quality is not as good.

Hi Guys
I need a couple of circuit boards and transformers from out of the Alctron HT11a.
I am hoping maybe somebody has pulled some out of a complete rebuild of the HT11a.
I have bought 2 of the new delivery of HT11 bodies from Chunger and already have the mod kits for the Alctron circuit boards.
If anybody has any I wiil pay to get them.
Thanks Spencer

Hi Guys!

First of all; big thx to Chunger for making all the efforts with the mic bodies; they are wonderful!

Just one note about the PSU:s before you happily start to solder away;
On the 7-PIN XLR, PIN 4 (white) is soldered to ground, which can be hard to see if you leave the XLR:s in the chassis after you take out the old PCB.

Sorry if it mentioned elsewhere or common knowledge, but I thought I'd mention it anyway since I almost missed this..  ::)

Best,
Michael

I will be out of town for the next couple of weeks.  The shipping queue has been mostly cleared except for 2 outstanding orders that I brought with me mostly packed.  They are missing Mullard 12AT7 tubes, and I have a re-supply inbound to my current location.

For orders placed 8/2 and later, I will process and pack as soon as I get back in the order received.

UPDATE:

SYT-5 gen. 2 microphones are on the boat and scheduled to arrive 8/16.

Chinese 35mm K67 type capsules will also be re-stocked around 8/16.

Also at that time, I will post microphone shockmounts as separate items as I have received some inquiries about 60mm U47 mounts as well as upgrade 44mm mounts for the HT-11A microphones to the current, more robust style.

 Went to insert my FET47 PCB into a GT-2B mic body, and I realized I didn't have any screws for it. Anyone know the proper screw size for the GT-2B?
Title: Re: Unmarked Donor Microphones, C12 Kit, and Associated Parts from the Motherland
Post by: mgronroos on August 03, 2014, 01:54:36 PM
They are standard M2 screws in the microphone bodies.
Generally, the shorter the better, but I cut mine to the right length which worked fine.

I just finished a D-U47fet myself the other day, and it looks very good in the GT-2B body!

Best,
Michael

gen 2 SYT5 bodies have landed.  They are currently in customs. 

After some initial contact with AMI, they have stopped responding to my inquiries so as of now, i still cannot get transformers.  In the interim, kits have been shifted over to cinemag transformers and prices adjusted accordingly.

I haven't had a problem so far with shock mount failures in the studio for the ones that I carry.  Can you elaborate on the issue?  I have had elastic failure which was resolved by re-crimping the ends of the band together, so I should inquire about stocking spares for those.

Sorry Chunger, I didn't mean I've had one of your product fail.
Just in general I have found the thread on the thumb screws strips easily.
I notice the shock mount you have with your latest run of bodies look a like a high quality than the stock standard hst-11a.
I might have to order a few of those as replacements when you stock them separately.

Cheers,
Ben

Could I please get a recap on the SYT-5 gen. 2? The tail piece that screws into the shockmount is extra long, but this is purely aesthetic? The mounting system cannot be easily raised to put the capsule at the proper relative height? How will this be fixed?

What will be the price?

I'm trying to plan for this U67 that has been waiting for bodies to be in stock.
Title: Re: Unmarked Donor Microphones, C12 Kit, and Associated Parts from the Motherland
Post by: kidvybes on August 20, 2014, 03:10:55 PM
I'm sure Chunger will chime in with the specifics, but from what I can see, it appears the only difference is that the factory extended the threaded part of the tailpiece, so it should not have any effect other than aesthetics, and once the mic is mounted, even that factor is further diminished (see post below)...

...IMHO, much less of an issue than the early run of SYT-5 bodies with the polar-pattern switch markings shuffled...

Post by: kidvybes on August 20, 2014, 03:22:56 PM
...it's interesting, that the Alctron MK47 replica body also has an extended tailpiece (but not threaded to the end), and that mic doesn't even employ a base-attached shock mount...seems the Chinese have an affinity for long tailpieces  ;)
Title: Re: Unmarked Donor Microphones, C12 Kit, and Associated Parts from the Motherland
Post by: chunger on August 20, 2014, 06:19:44 PM
Gen 3 will fix the tailpiece aesthetic.  I may have a batch of replacement end pieces made so folks can convert, but this will take some time to accomplish. . . EVERYTHING takes forever when dealing with overseas factory I've found.  The headbasket meshing ended up being a major exercise in frustration, so I decided to have them build the batch at this stage.  Otherwise, we would never get any mics in hand it seemed.

Part of trying to be a "valuable" customer is following through with some big orders so the factory knows you are not just kicking tires. . . especially on the first order.

I'm working on better ways to coordinate with the factory and hopefully, we will be able to figure out a good work-flow.  I'm thinking I will need to prototype here in the US and send a completed sample for reference to China so they understand exactly what I'm looking for and do not get "creative".

As for raising the capsule mount, you can use any stock material (plexiglass, delrin, brass, etc.) and drill 2 holes spaced 8mm.  Then use longer M2 screws to attach the rubber mount.  This should be easy enough to DIY and I will work on a bolt-on solution as well.  I specifically requested the use of the same shock-mount, but again, the factory decided to use what they are familiar with instead which is unfortunate.  I may need to supply them with capsule mounts in the next rev.

No boxes for SYT-5 yet.  The final price of the bodies ended up being much more than originally quoted so I ran out of funds on this batch for wood boxes.

UPDATE:  Microphones have landed and I picked them up today.  They will go live on the webstore tonight or tomorrow.  There will be shipping delays as I expect a number of orders from folks who have been waiting.

UPDATE: Gen. 2 SYT-5 bodies are officially in stock and live on the webstore.  The final production units look better than the 2 samples that I received previously.  There is absolutely no danger of running out of stock on gen. 2 SYT-5 bodies for quite a long time.  We ordered a lot of them. Keep calm, and build on!


note:

- GT-2B and HT-11A wood boxes are in stock now will be listed as separate item soon

- Shock Mounts for HT-11A (updated dual clamp variant), GT-2B (M27 threaded base), and U47 (60mm diameter) are also in stock and will be listed soon.  Probably tomorrow night.

- Type 1 headbaskets are running low in stock, but a replacement batch is in plating phase right now and will be sent to me via air freight which only takes a couple of days, so if all goes well, we will not run out of stock for any length of time.  These are being produced by a new metal factory and we should see an improvement in fit from the previous batch.

- AMI is communicative and has invoiced me for a transformer order.  Unfortunately, they have also scaled back the volume discounts I was purchasing at previously. . . at least temporarily.  For now, I understand the business is in major flux so I went ahead for restock order, but the margins were already very thin and we have had some T14 failures that incur loss for shipping replacements.  Long-term, I do not know if we will continue to stock AMI products, but it is good to see them back to production.

- Cinemag CM-13114's are out of stock temporarily, but a large replacement batch has been shipped, so there may be slight additional delays on orders that contain CM-13114.

Just a question about pricing: on your website is says the double sided edge terminated capsules are $32. (The ones with the blue tape)
But when I select the item, the price is suddenly $70, a big difference!
So: what is the correct price? (Or am I completely mistaken?...)

...the 35mm center-terminated K67 capsule was the $32 option but is currently back-ordered, which is why it's temporarily removed from the drop screen list (click on either arrow under the pic)...the C12 double-sided edge-terminated capsule is $70...

There are many good options for U87 capsules.  Eric Heiserman and Beesneez both make "premium" K87 type capsules.  I'm sure there are other capsule builders as well. I have heard great things about Shannon Rhodes at Micrehab.com .

If you want the closest to vintage, you may consider buying a replacement capsule directly from Neumann via Sennheiser.

Currently, your reputable PCB kits for U87 build would come from Dany Bouchard.  His website is http://www.vintagemicrophonepcbkit.com (http://www.vintagemicrophonepcbkit.com)

You want either the square style DU87 boards (green, rectangular, 2 boards) or the new D-87M (blue single board).  I made a build thread for the original DU87 boards, but I am not sure if those are still available.

That is what I would currently recommend for a U87 clone build inside the gen. 2 SYT-5 body that we carry.

All current orders except for 2 have now been shipped.  These 2 orders are awaiting Eric Heiserman HK12 capsules which should arrive any day.  These 2 customers have been emailed.  It appears Eric was caught up in M49 microphone body production crisis which has delayed his capsule production somewhat.  I should be well stocked again shortly.

I have a trip planned from Sept. 23 to Sept. 29 and will not be shipping any orders until I return.  Refunds if necessary will be processed immediately.

Hi Chunger,

I know you discussed the need for a spacer under the capsule mount to get the capsule oriented properly in the new SYT headbasket. What size spacer is needed? I have a variety of nylon spacers available to me, I'm hoping one will work. If so I might even have enough to donate some to the cause...

Edit: Never mind, I found it. The capsule mount needs to be raised by 8mm.

Yea they held on to it for a few days, I am guesssing to decide what they wanted to charge, in the end it was £21 for 2 of them, which at the end of the day is not a major issue.

Yes.  I am getting a shipment of replacement latches. . . Just in case some people already bent theirs.  As well as the proper thickness  felt pieces.  It will ve a bit of a pain to strip off the old felt and glue the new stuff on, but should resolve the issue. 

A faster solution may be for me to attach some course grit sandpaper to the outside of a 60mm body tube and sand down the thick felt.  I will have to experiment with it.

Either way, ill get it sorted out.

You can also use a excato knife and cut half the thickness of the felt away.  It takes less then 5 mins with a new blade.

For U47 shockmounts, you can also file the felt.  It will fuzz up and you can re-smooth it after removing an appropriate amount.

UPDATE:  In-stock Type 1 headbaskets are now transitioned to new factory supplier manufactured from the same original tooling I had made.   The assembly and mesh alignment  quality is much better now.  I believe the original metal factory has actually stopped offering the single mesh headbaskets because they have too many rejects upon assembly.  From the units shipped in the original production run, I estimate about 8-10% B-stock rate primarily due to mesh alignment problems. 

Other notable differences. . . The finish is more consistent from unit to unit.  More tool marks show in general.  I'm assuming either they are using a different grit polish compound or are not leaving it on the wheel as long as the previous factory, but the first production run had a high number of units with slight pitting in the finish which is not evident in the new run.  Also, the tolerances in the base piece have been tightened up a hair, so they fit just a bit more precisely to the tube for a little less wiggle.

Overall, i am happy with the improved consistency even though cost per unit is slightly higher.  It was not possible to easily correct the tooling to include the "bend" in the hoop originally specified, so for now, I am staying with this process for Type 1 and Type 2 headbaskets.  We are still utilizing first run Type 2 headbaskets currently from the original factory.

hi Chunger,   I just ordered some parts this morning on your site.  Saw you are out of the c12/251 parts bag.
I'm only short a few parts and wonder if you could sell me any of the following?

5000pF x 2,  100pFx2,  30M x 2,   250M x2,   (or 100M x 4)

thanks,  Lance

MK67 "bare bones" kits are live on the webstore.  Unofficial recommended components if you are wanting a more inclusive "kit".

- Alctron TPS-100 powers supply
- Gotham GAC-7 cable
- 2nd gen SYT-5 body

The official build recommends modifying the stock Alctron PSU, so the cost for that component is minimal.  The following items would need to still be sourced:

- EF86 or alt tube
- capsule (Neumann/Sennheiser, Eric Heiserman HK67, etc.)

Heiserman capsule and Amperex EF86 in prototype build below:

This is Max's recommended setup so i am building according to his specs.  The next revision of our C12 psu has floated heater ground as well so should be able to be used more "universally" for various mics including U67.

You mean the regulated universal one? or revision 2 of the passive C12 supply?  I was just thinking that the C12 supply could modified to work as well, and be more elegant than the fugly stock Chinese supply with it's generic 85C caps and lack of terminal blocks.

Both of them will have this. . .. the regulated one and the passive one (C12 2nd revision). 

In the interim, i see no harm in running the modded stock unit. . . It is a righteously priced option and if you put the trim pot in the original pattern switch location, can be accomplished in probably under 30 min.

Hi Chunger,
Any idea when you'll have some of the AMI transformers back in stock at your store?    I know the story with AMI, just wondering if you had any feel for when they might be back on their feet.  The transformer is the last part I need to complete my U67.  Alternatively, if it's going to be awhile yet, would you sell one of Max's transformers by itself?  I've already long ago built Poctop's board....
Thanks!

Hello Warren,

All AMI transformers are currently in production and shipping.  You can contact them directly and order.  The only hinderance to me being re-supplied is they are no longer offering me the same volume pricing arrangement that I enjoyed with Oliver, so it is possible I will not be able to carry the product line in my webstore.

We have been going back and forth a little bit with conversations.  Do not hesitate to call them up and place an order.  It is likely in stock.

Alctron mk47 stripped bodies are complete at the factory.  . . I should have these in hand and available in 3-5 weeks if all goes well.  These are 3 rail 90 degree orientation, so they are very conducive to PCB based builds.

Yeah. . . the cost is higher than I wanted from the factory, but I think these will be ~$270.00 and include the body and a shock mount. 

I am still developing the gen 2 SYT-5 bodies in short and mid-length form factor which should be better machined and have better rails.  It is possible those will be better priced but development always takes forever so who knows when those will be ready.

Searching for a good low-cost 87/67 body option, I have located a good candidate that fits the large rectangular style PCB's.

(http://studio939.zenfolio.com/img/s5/v125/p951791519-4.jpg)

(http://studio939.zenfolio.com/img/s7/v166/p1012021049-4.jpg)

It seems like the materials, construction, and assembly all seem to be truly bottom of the barrel!

(http://studio939.zenfolio.com/img/s4/v9/p1059066268-4.jpg)

The frame base and end cap are made from Chinese "mystery" pot metal.

(http://studio939.zenfolio.com/img/s3/v24/p775837499-4.jpg)

The casting is truly horrible.  It is likely though that like many samples I have received, it is a factory second.

(http://studio939.zenfolio.com/img/s5/v129/p1052384216-4.jpg)

And, we have a 100% useless solid aluminum capsule mount with no dampening qualities whatsoever.

(http://studio939.zenfolio.com/img/s6/v145/p818463268-4.jpg)

All that being said, the body does, in fact hold the current PCB's without modification

(http://studio939.zenfolio.com/img/s3/v8/p850596616-4.jpg)

And, the use of aluminum tube (I requested anodized finish for the sample) and cast parts reduces the price to about 60% of the current SYT-5 body which is machined brass.  Which would be fantastically cheap.  The top plate also fits the 1st gen SYT-5 capsule mount which did have some good features like insulated wire pass-through and easy raising of height with an 8mm M3 standoff.

From what I am seeing in terms of assembly quality, I will not venture to improve or alter the mesh configuration as i believe it would be an exercise in futility with this factory.

All of the above caveats in place, I do think the cheap or entry-priced bodies are important for DIY.  I would rather someone spend the extra money on a good capsule than a prettier body if it was a matter of one or the other.  Also, if building a "fleet" of drum mics that can be abused, this may not be a bad option.  Also, the base cap looks to be M21 threaded which would accept a few cheap low-profile swivel mounts.

Hi Guys,
I am about to pull the trigger on this c12 build but had a few questions.

Before this thread one of my first builds was  a 251 clone in an apex 460 but it had issues so I sent it to JJ Audio and had them reworked it into their Dutch 251 clone.  With their tone colors of old resistors and caps that they had on hand at the time.    I already had everything  including the 5 star 6027 tube, t14 trans and Tim's capsules it was kinda of easy for them to rework the circuit closer to a 251. 


I wanna make this build as I understand a lot more now and I wanna swap the tube and capsule from the 251 I have  into this new c12 build and compare the sound qualities between the two. 

My questions are

Is the type II head basket still better than the type I?  I read that the type I was flimsy.

Are all the parts in stock and can it be shipped all together?  Mic w/o chord, trans, pcb and components. 

Thanks
-Scott

The type 1 headbasket is not as strong as the dual layer variants.  I have not had any complaints regarding strength but a few people experienced ringing which is mitigated by gluing completely around the base perimeter.  That being said, most headbaskets in circulation are type 1.  More than 400 now in the same configuration.

AMI T14's are out of stock.  I recently had an unexpecred mass failure of 6 units in the batch and need to coordinate replacements.  Moving forward it is likely i will no longer stock the AMI's.  They are in production and available directly though.

All other parts that are listed as in stock on the webstore are in fact in stock.  I am currently 14 days behind in shipping.  I do bump orders to the top of the queue for special circumstances (travel, studio session, etc.).

We are on the cusp of transitioning pcbs and BOM to a new revision and product line restructuring.  A dedicated Ela M251 pcb will be in that mix.  Other changes should be fairly minor.

6 out of how many? 6 out of 10? 6 out of 100?

6 out of 25.  They are actively looking into the issue.  I have had a steady failure rate of about 1-2 units per batch continuously and i am informed that in am the only customer who has ever exerienced this. 

AMI reports 0 failures for all other customers shipping worldwide.  In a conversation recently, I discovered i am the only person regularly receiving quantity shipments in bulk packaging.  They are testing the packaging now to see if that was the problem and looking into changing to a more robust connection wire.  It is currently 30 gauge single conductor teflon.

Once i started testing all transformers on my bench prior to shipping, i experienced almost no customer side  failures but still steadily had failed units that AMI always promptly replaced.  I also hate being the sole "problem" customer who is constantly claiming broken products and problems that nobody else has.

Anyways, from my side, the new volume pricing structures can no longer account for shipping costs incurred when i have failures that i need to replace and it inevitably happens out in europe or australia.

All of AMI's transformers are in production and available direct.  Also, i have no reason to doubt the integrity of their 100% success rate directly shipping T14's to customers.  So that along with their flawless customer support track record should let people still buy with confidence.

For me, however, it does not look like i will be able to stock these moving forward.  I am short of AMI's currently established annual purchase volumes required to be an official vendor.

New shipment of metal parts is loading onto the boat this week.  New items that will be available when these arrive:

- Alctron MK47 stripped bodies (U47 style)
- loose HT-11A shock mounts (larger dual latching style)
- loose GT-2B M27 threaded shock mounts (fit Gen 1 SYT-5 bodies and of course GT-2B)

GT-2B microphones will be re-supplied in this shipment as well in time for un-interrupted supply.

MK47 complete kits will add a mid-priced option with the MK47 body when this shipment arrives.

As for timing, I am not sure when these will land.  I have had extended delays on at least 2 shipments in customs so far, so I will not attempt to make predictions.

Yes, the first picture is Gen 1 which is a wider mesh than the 2nd gen which is closer to the original.

It would be great if the machining on the base could just be a slot so folk could Dymo their own labels in there?  The Behringer B2 has this only i recall the diameter of the slot is smaller than the smallest dymo reel size :(  Could use the plastic or even metal embossed tape as per: http://global.dymo.com/ieIE/LabelsOverview/Embossed_Tapes.html (http://global.dymo.com/ieIE/LabelsOverview/Embossed_Tapes.html)

Searching for a good low-cost 87/67 body option, I have located a good candidate that fits the large rectangular style PCB's.

A few important updates:

- GT-2B microphone have been put back in stock.  I located one more carton of bodies at the bottom of my pile.  This should maintain stock until the new shipment clears customs near the end of the month.

- All orders are SEVERELY delayed right now as I had a series of work deadlines and the household is a bit sick right now.  I will be attempting to gain ground on the shipping queue late this week.

- We are out of stock on C12 PCB sets and will be moving to a new revision board with a few exciting technical improvements.  Details to come as I prototype the new boards.  The power supply will change slightly and new build documentation is already completed to reflect those changes.  http://groupdiy.com/index.php?topic=58054.msg739085#msg739085 (http://groupdiy.com/index.php?topic=58054.msg739085#msg739085)

- pending orders for old revision C12 boards will be given some options. . . refund, discount and shipment of current revision prototype PCB (100% functional), or hold order until production batch of new revision boards arrive.

Can you tell us about any of the changes Chunger?  Are you guys floating the high-Z section now?  I think that will improve troubleshooting since a lot or issues are due to the flux contamination and the difficulty of getting the boards totally clean.

Also, any update on the new version of the GT-2B and the MK47 bodies?  MK47 PSU?

Thanks!

Same here, plus a type 2 custom basket and parts. Hope he's catching up on processing delays.  It's my first build, so I'm going to try an RK-12 capsule and also an M251 conversion layout. Can't wait to see how it compares to a vintage C12.

UPDATE:  I have received a re-supply shipment from China and unloaded it today.  I apologize for the delays on this shipment.  Port strikes up and down the US West Coast and x-ray examination of the container with my cargo severely delayed freight delivery times.

The following items will be updated to the webstore shortly.

- Alctron MK47 (U47 clone) microphone bodies
- U47 shock mounts (back in stock)
- upgrade HT-11A shock mounts available separately
- GT-2B M27 threaded shock mounts available separately
- GT-2B microphones (back in stock)

I have a lot of development work to do for verifying the next generation C12 PCB sets and am still currently working with a long packing backlog, so I apologize for the delays.

The body kits will certainly still ship with shock mounts.  The loose mounts are available primarily for people using older apex 460s or very early runs of mics.

Currently packing orders placed ~18 days ago.  I am in development phase for a few key items so shipping lead time delays will continue to be long until I am through verifying the rev. 1.4 C12 and ELA M251 microphone boards.  The next revision power supply boards are already verified and fully documented.

Hi Chunger,
I just received a SYT-5 from you. Beautiful mic body, I'm very pleased! I have one quick question; do you know what screw size the holes for securing the circuit boards are?
They're some seriously tiny little guys and I'd like to try to find the right ones before I do anything along the lines of drilling and re-tapping them.
Thanks!

Coincidentally,  if you decide to re-tap a M2 screw, the hole doesn't quite leave enough thread depth to reliably tap a 2-56 screw...I found this out the hard way after stripping a few.  If you re-tap, move up to 4-40.

So far I've only received (1) MK47 mic body and (2) shock mounts.

Can we get the other mic body shipped out please?   Thanks.

Hi James,

I have not received emails from you recently.  Please make sure you are sending to [email protected] .   That must have been a late-night packing error.  I will get another MK47 body out to you ASAP.

So I guess the SYT-5 bodies no longer accommodate the capsule mounts that have adjustable height, nor do they have holes for the capsule leads. Kinda wierd. Has anyone else dealt with this? Any suggestions? I'm really getting close to finishing my mic but I dont have a drill press to make my own holes... and I'd like my capsule to sit at the right height in my headbasket. Hopefully the capsule leads will still reach the PCB without the holes.

best solution is spacers and longer (12mm length M2 screws) if you want to use the current mount provided with the microphone.   I tried to get the new factory to use the 1st gen mount, but as things go in China, they did not and stubbornly used their mount.   I have few spacers on hand and will post it up now on the webstore.

Hello Emil,

Sorry for the delays.  The latest word I got from Eric Heiserman today was he has been out of town for a family medical emergency.  Capsules were originally supposed  to be in my hands more than a month ago.  My most recent shipment from him only included a fraction of the capsules that I ordered.  As always, please let me know if you require a refund at any time.  Your order will ship as soon as I receive my anticipated capsules from Eric.

He has had no luck trying to reach you by email since then - so the question is: When can he expect to see his capsule?

What is the time frame for the new version C12 kits?

Hello Mulmany,

We are running low on capsules right now and that is holding back the "complete kits".  All other items are in good supply right now and I've priced everything so there is no cost difference between ordering all the necessary parts separately or all together because DIY people often like to select their own specific parts combinations.  If you require a complete C12 kit, please order the following items:

capsule - various suppliers
tube - various suppliers (we do stock the NOS Mullard 12AT7 alternate tube)  I recommend Christian Whitmore for tested NOS tubes of any type.

- C12 PCB set
- C12 electronic parts kit
- HT-11A body kit (Type 1 for a C12 clone. . .utilize the "no cable" option if you plan to use premium Gotham or Mogami cable)
- Cinemag CM-13114 transformer (alternately you can order AMI T14 directly from AMI)

- optional Gotham GAC-7 cable

Available capsule options for chambered backplate original type are:
Tim Campbell
Eric Heiserman
Beesneez

Available capsule options for K67 based edge terminated are:
Studio939 (very low stock currently)
Microphone-parts.com
Peluso
likely many other suppliers

I just decided to do my own PTP version of the PSU for the MK-U47. Chunger has such a great play-by-play already, and I was already planning on putting my resistors on a heatsink. Just didn't make sense to use Zayance's board when half the components would be off of it already.

I'm also going to add a meter too, and a voltage adjust pot on the front panel. :D

I was talking to a few alternate factories about getting boxes made, and i scraped too close to the bottom of the barrel  :o .  The samples were laminated mdf and they were truly horrible. 

The next incoming freight shipment will have a box that fits the mk47 and syt5 bodies.

Our pcb has been laid out for mk47 power supply.  Waiting for a prototype case from dan.  Sllllloooooow going on that project but it really is a straight forward point to point build.

Thanks for the update Chunger! Your awesome build guide from before gave me the confidence to try my own PTP like you did. I'm going to add a meter! Thanks for the awesome work and your incredible contribution to the DIY world.

A few new items on the next boat from the motherland.

1) CHEAP SYT-5.  Sometimes the build does not need to be shiny and special looking.  It just needs to hold the PCB, capsule, transformer, XLR jack, and stay together.  Also, it would be nice if it looked decent from 10 ft. away, but you don't sweat the finish imperfections.  These will have anodized aluminum body tube, a standard 2 layer headbasket mesh as well as "mystery Chinese pot metal" internal parts.  The price will be fantastic though, and they will hold to the same mounting points and kit dimensions of the SYT-5 body so all currently available kits will be compatible.   The nice current 100% machined brass gen 2 SYT-5 will continue to be available and the 3rd gen is under development.  The cheap body is not replacing it. . . just adding another option for people of all budgets to consider.  This body scrapes as close to the bottom of the barrel as possible yet still provide a functional, reliable body to work with.

2) CHEAP mk47 body. - same concept as above.  The headbasket will not be vintage-correct meshing, but the internal rails and dimensions are identical to the 90 degree 3 frame rail mk47 microphone body.

3) Wood boxes for all microphone models. - The SYT-5 and mk47 (U47) will share the same box while GT-2B and HT-11A will have their own box sizes.

4) Type III headbaskets will be back in stock for the HT-11A bodies.

5)  Budget edge terminated capsules.

These are the items nearing completion right now and once the batch is completed, everything will be consolidated and sent via cargo freight.

I do not think we will run out of stock on any mics soon, but the HT-11A bodies are lowest right now with replacements coming this batch.  Type 1 headbaskets may run out again before the next re-supply, but supply may just be able to hold out without any interruptions.

The following items are starting production now (lead time 3 months)

- gen 3 SYT-5 bodies.  These will "fix" the bottom bell shape and proportions.
- type 1 and type 2 headbaskets for HT-11A (re-supply batch. . . no design changes)

Hi Chunger,  Any updates on the shipment from China?  Would love to see the SYT-5 v3 or the cheaper mic bodies/pricing

A new batch of microphones from a couple of factories is complete and we are sorting out consolidating and ocean freight details now.  The cheap aluminum/cast zinc SYT-5 bodies are included in this shipment.  These should end up costing about 65% of the higher quality machined brass bodies we currently have.

I will continue to have both types of STY-5 body made (high quality and low cost versions).  It's nice to have choices.  The low cost option is nice for people looking to build drum mics or other "high-risk" situations where a more expendable body is appropriate. .  . or, they don't care as much about the finish quality.

In this shipment

- HT-11A body re-supply and type 3 headbaskets
- metal transformer bell-housings for HT-11A body
- cheap SYT-5 body
- cheap mk-47 body
- wood box re-supply for HT-11a
- wood box re-supply for GT-2B
- new larger wood box to fit SYT-5 and U47 microphones

ETA likely a bit more than a month from now.

Hi Nick,

Unfortunately the parts kits are out of stock right now and I need to settle my recent very large China order before I will have funds to re-stock those.  For now, please refer to the BOM on the build and support thread.  It takes a little more legwork, but between Mouser, Justradios.com,  Amazon, and Erse Audio you should be able to get your hands on all necessary components (per the kits that I stock. . . there are other choices as always in DIY).

Type 1 headbaskets and HT-11A body kits are also very low stock right now. . . like less than 5 units.  HT-11A bodies are completed at the factory though and we are arranging ocean freight right now so those should be re-stocked "soon" .  . . meaning in the next 3-6 weeks depending on how long customs takes.  The Type 1 headbaskets will take longer but production deposit was placed a while ago and the factory has started building them.

In stock in healthy quantities for the C12 project:

PCB kits
Cinemag CM-13114
Gotham GAC7 cable (if you choose to go that route)
Type 2 and Type 4 headbaskets
TPS-100 power supplies

Binder connectors have been ordered for new "Budget U47" bodies.  Those should go live shortly along with loose XLR inserts (3 pin and 7 pin), rubber type capsule mounts, metal bell housings for HT-11A bodies, and a few other helpful small items.

I am expediting a shipment of 100 Type 1 headbaskets by air mail to temporarily re-stock prior to the next large freight shipment which may be some time.

Sorry about the increased shipping costs lately.  The US Postal Service very recently increased all of their rates sharply domestic and international.  I try to make my webstore's shipping calculator accurate and do refund excess shipping/packaging costs when the orders are processed.  If your order is "strange" and contains a lot of very small items, or a lot of microphone bodies, this could skew the automatically generated shipping costs, but I refund excess when I actually pack the box.

Update:

We are moving to Gen 3 SYT-5 microphone bodies.  The only change of note is the profile of the bottom bell housing which I was not 100% happy with on the Gen 2 bodies:

(http://studio939.zenfolio.com/img/s1/v54/p1944378340-4.jpg)

Otherwise, all of the machining and headbasket soldering looks to be a bit cleaner on this production run.  I also ordered body tubes without switch markings as well as bodies without switch slots this time per customer request.  I will be adding those options to the webstore soon, but if you are looking for those sooner, please contact me via email.

I have my production run of acrylic spacers in hand, and those are updated to the webstore.

HT-11A metal bell housings are in stock now per customer request. . . the next most requested HT-11A item is the rubber tube mount, so I will inquire with the factory about sourcing those parts separately in my next run of parts.

I apologize for the long lead time right now as I have recently returned from traveling and am catching up on a few work projects at my job.  Orders are being processed, and hopefully I will be able to gain ground this weekend clearing the shipping queue.

Sorry guys, my dayjob has been nuts for the last 1.5 months, and I am knee deep in a remodel project, so response times are sub-optimal right now.

I do have 3 pin XLR inserts.  Shoot me a direct email with a list of the parts you need and a shipping address and I will invoice you via paypal.   [email protected]

Hey, could somebody with a SYT-5 body please give me the outside diameter (top and bottom) of the body tube?

Quickly from one sample:

top of tube measurement inside the notch that fits into the headbasket -  2.259"

widest point on tube - 2.305"

narrowest point at base of tube - 1.970"

Hello Chunger,

Is there any news on the C12 kits?
Are they going to be stocked again? Also the premium kits?

Hello all, i salute the group DIY comunity via my first post! I am a guitarist and music producer from Bucharest, Romania (EU) and I'm a beginner with electronics, so please bare with me! I just tracked some acoustic guitars recently at a friend's studio in our city and i was blown away with the quality of the C12 clone (Tim's capsule) perhaps the best studio mic I have heard so far and he told me about this site! Great job guys, highly apreciated!
I plan ordering the parts, including Tim's capsule if I 'm lucky enough to reach him. I was a bit dissapointed to see the complete kit is out of stock, i want this so badly in order to have better recording quality and produce better and inspiring music, hopefully! :)

I want 1 x  C12 Microphone Kit Complete Premium kit, can u please tell me if and when they will be available again?
the price posted on site, 457$ is for the budget one? how much the premium kit costs?

Is there other alternative if the complete kit is out of stock, to buy the parts separately? i need a little guidance since this is my first DIY project ever, i will have a local professional engenieer/electronist for the soldering part!

Thanks
I await your answer, Chunger! Best regards, Marius

Hi Marius,

You can buy the following to make your microphone (same as "premium kit")

from my webstore:
-HT-11A body kit Type 1  (without cable)
-C12 PCB set
-C12 electronic components kit
-Cinemag CM-13114 transformer
-Gotham GAC7 (with 7 pin xlr)

Then, source the following 2 items separately:
-NOS GE6072A tube (recommend Christian Whitmore for high-quality tested tubes)
-Capsule (most people use Tim Campbell or Eric Heiserman capsules)

So, everything is in stock and shipping except for 2 components.  In order to build the mic, you actually don't really need my kit at all.  There are many ways to build a C12 clone, and this is just one convenient way to do it.

Best of luck!

Can someone tell me if the Budget-YT5 body kit from studio939 would work for a u87clone consisting of the pcb kit from danny, the hk87 capsule, and a sowter tranny? (Trying to build something along the lines of the SA-87 by stam audio)

Or would I need the SYT-5 gen 3?

Yes. to the first ?
2nd - This low-cost body kit shares the same internal dimensions as the 100% machined brass GEN 2 SYT-5 body kit , but material specifications and finish quality have been reduced to the lowest possible standards yet still produce a functional body.

The Budget yt-5 body will work with the current 87 and 67 projects.  It has been pretty impressive in terms of fit,  finish, and consistency for a low cost body!  I would not hesitate to use it.

Hello,

shipping queue is currently 7 days, so your order should have shipped and typically, tracking information is emailed when the label is processed.  For tested 6072 tubes, check in with Christian Whitmore.  He can get you any vintage tube you require.

The Gen 1 units had a 27mm threaded base, 2 screw attachment for the headbasket, and a  dual layer mesh.  They also came with "ring type" shock mounts that wrapped around the body tube and tightened.  Gen 2 and 3 use 24mm screw type shock mounts and have 3 layer headbasket mesh.

The PSU board cannot be used for C12 and U47.  The U47 supply is different from most other tube mic power supplies because it is a single 105V rail that supplies both heater and B+.  It also produces a lot of heat, so it is typical for the build to use a larger, better ventilated case.

I recommend building a separate power supply for U47 builds.

BUUUUUT, I have an experimental 90V transformer that could work with the PCB to supply the 105V U47 using just the passive  B+ section of our PCB setup.  This is not tested though.  The reason for using a lower power transformer is to try and reduce the heat generated.  But it could also have detrimental effects to the filtering.  This would also not be compatible with the C12 because the transformer does not have a 9V tap for the heater side of the power supply.

I have not prototyped and tested the setup and only have 2 sample transformers on hand for this application.  The best current advice is to use Zayance's PCB and build the U47 PSU that way.

I apologize for the extended delays restocking the C12 PCB sets.  There is an ELA M251 prototype on my bench  that I am almost finished confirming.   I will order C12 and ELA M251 PCB's together in bulk once the prototype is confirmed.  After this, PCB's should be in stock.  Please standby.

I have added a few very small items that have been repeatedly requested.

3 pin and 7 pin XLR inserts that fit most imported microphone bodies
(http://studio939.zenfolio.com/img/s9/v88/p2588501452-3.jpg)

Soft tube socket mounts for HT-11A microphone body
(http://studio939.zenfolio.com/img/s1/v22/p2588501293-3.jpg)

A new single screw capsule mount with slotted saddle mount holes that should fit most 34mm capsules without drilling the saddle
(http://studio939.zenfolio.com/img/s10/v101/p2588501102-3.jpg)




And, the big one, M49 bodies are now in stock and live on the webstore.    I apologize for the super expensive Binder 961 series connectors.  . . these are often requested as an option.  I may attempt to have an XLR insert base piece made to have a lower cost option in the future.

Yes,  Matador is working with a new representative at the PCB fab and they are requesting more details than the previous rep was asking for.  So, they are in the process of sorting everything out for the production run.  Every time this happens, it seems Matador has to do a big run-around to satisfy all of the queries.   We are trying to get them printed ASAP.

Hi Chunger,

Any chance of procuring the M49 shock mount by itself?

Thanks

Hello Chunger
Are dimensions of the microphone body CU49 on your store same as original Neumann M49 (diameter: 76-80mm)?
I sent you message please check your email.
Thanks

Hallo Chunger,
It's possible to use your U67/U87 SwitchPCB as a direct replacement for the old broken Plastic Switches?

Hallo Chunger,

The parts are not physically cross compatible with original Neumann body.   As far as I know Sennheiser still supplies all replacement parts for repair of vintage units.

I received a tracking number for my package I ordered recently - it was a fairly big order though.

Emails were a bit sporadic, but chunger always got back to me and he was helpful - I’m sure he’s just busy with other things...

Hello,

Apologize for the recent delays.  I have a sizeable backlog of orders right now and am working through them in the order received except for special circumstances like upcoming sessions or travel plans where I expedite some outgoing boxes. 

Email notification is sent out when the shipping label is generated and if you require a refund any time prior to shipment, i can process that immediately.

I am still waiting for your response on mail about CU49 kits.

MK47 bodies will be back in my next factory shipment.  I will be ordering enough to be in stock for some time.   A few retail microphone builders started using the body kit and that rapidly depleted my stock from this batch, but I am aware of it now and will restock accordingly.

What was your query about the CU49 body kits?

Just got a message from TC that my capsule is ready for shipping! So excited! Hoping to be able to order pcb and donor body etc soon!

Still going a bit back and forth about wether to go c12 or 251 style. Some people say that the 251 is the best of both worlds being more balanced like a split beween a neumann and a c12. Any thoughts?

In my specific recording environment, the M251 is a bit more versatile and the C12 sits mostly as a special use microphone.  But, every recording environment, setup, and subject is different so it is it is hard to make the determination without actually trying it.

I’ve heard more than a few say exactly what you say actually!

Seems like the C12 build wise might be a bit more straight forward since the pictorial is so easy to follow. But I’m leaning towards the 251 still as it seems to be right up my street!

Maybe a 251 pictorial will be up when the time comes? Sitting here looking at my newly arrived CT12 longig to order and put this together!   ::)

I have all of the photos for the 251 build already edited.  I just need to finish the write-up.  The build is just as straight forward as the C12 on the new boards, and I do have several of the verification samples on hand for anyone who might want to give it a go.  Both C12 and ELA configurations should be in stock soon. . .well, as soon as factories re-open in China.  They are on their Chinese New Year holiday and pretty much the entire country is shut down for the break.

GT-2B's are in stock.  I am working on another production run of HT-11A, MK47, and possibly another mid-tier U47 type body right now.  Unfortunately, I will be out of stock on some mic bodies for a stretch, but I am making a big production run, so they should stay in stock for quite a while once I get them in hand.

Hi Tommy,

sorry for the delay,  I am extremely behind in packing and shipping right now but have your GT-2B order in the system.  You will receive tracking information by email when the shipping label is generated.  I should be getting a large batch out early next week.

Hi Chunger,
I emailed you a couple of days ago and haven't heard back. I received the SYT-5 body I ordered from you and the first thing I noticed was that the headbasket was all jacked up. (see photo) Can you send me a replacement headbasket?

After being told the engraved body was not in stock two weeks after I ordered it when it was in stock, and then having to settle for the unmarked body for my birthday build, I'm not happy about this. This looks like "B" stock and is not what I was expecting when I ordered a brand new mic body.

I have no doubt Chunger is the kind of guy who will make this right. I get it that he's a very busy guy, but I just find it frustrating that because there is no damage to the shipping box, or the wooden box the mic body was shipped in, it would seem it was shipped with this headbasket defect. And even more frustrating that customer service issues don't seem to merit a response.

And even more frustrating that customer service issues don't seem to merit a response.

I have observed damage to a few HT-11A and SYT-5 bodies shipped inside of their wood boxes and generally send replacement headbaskets out to replace the damaged units. 

If you are truly unhappy with your build and the body kits that I try to make available, feel free to send everything back and I will refund your purchase, your shipping, and your return shipping costs.

Headbasket damage happens in very few instances I presume as a result of a sharp impact directly on the flat side of the box which causes the mic to jar enough inside of the soft foam to impact the headbasket.  I do not ship damaged mic bodies unless it is explicitly agreed that the customer wants a B-stock unit, the defects are clearly stated in the product description (ie., very cheap product with possible manufacture defects), or it is an item that does not get individually opened and inspected by me before shipping.  The SYT-5 is not one of these items.  I have been unhappy with escalating shipping costs for a lot of these microphones, and the trade-off I have made is to continue shipping in the most economical way possible while packing everything in what I feel is a reasonably secure way.  The alternative is to transition to larger boxes and more packing materials which would drive shipping costs significantly higher for everyone.

To date, all headbaskets damaged in transit have been replaced or microphone bodies refunded if no longer in stock.  The examples below are from customers and in each case, the external packaging exhibited no signs of traumatic crushing and wood boxes were intact.

He’s already said he’s really backed-up, so please hold-tight. As I’ve mentioned here, I’ve had stuff ship within a few days to over a month from him and never hear anything; it’s normal and he has always come through and I’ve never heard of any time he hasn’t. Hopefully you did enough research prior to putting in your order to already know all that though. I get it though, you’re probably just antsy and the sqeaky-wheel and always gets the grease and I’m known for never being squeaky even when I probably should be!

I know this isn’t Amazon, thats just an unnecessary thing to say... I just feel a line has to be drawn when I have the right to wonder. It’s not like 2 days have past...

Even if he has a day job, there has to be some form of dedication to hold up the other end of the deal when sending the invoice and taking the money right?

 3 weeks is right about that time for me to start wondering why I won’t get a response at least.

I’m sure it will all turn out just fine though, not good at the waiting game! :-)

Wondering the same.... any updates?

Chunger,
Been a couple of months since we asked last, but any idea as to when the SYT-5's are expected back in stock?  I really need four of them...

It's been a while since we've heard from Chunger. Does anyone know if he's shipping orders from his site?

Update! 

I have an incoming shipment of microphone parts from various factories. 

- Alctron MK47's will be restocked
- U47 shock mounts will be restocked
- HT-11A bodies will be restocked (all headbasket types still in stock)
- HT-11A shock mounts will be restocked
- U47/SYT-5 wood boxes will be restocked

I will not put them live on the webstore until I get my hands on the mics to make sure they are ok.

- SYT-5 marked bodies are still having finish issues.  Unmarked body tubes still available, but it will at least be another cycle before I get marked tubes back.  Budget YT-5 bodies are still in stock and compatible with all kits.  These have screen printed markings.

- Budget 47 bodies were not re-ordered.  The quality control was so bad on this model that I couldn't justify another order at this time.  I will search for a better low-cost alternative for this model.

The bodies have not yet made it on the boat, but they will soon.  Ocean freight and customs clearing timing is highly variable but I will update again when I have the new shipment in hand and ready to ship.

Chunger, I placed an order on your site about two weeks ago. Are you close to shipping it? I can pick up in person if need be. I live about 10-15 mins away from you if you're still in the East Bay.

Hi Jordan,

I was short a few 3 pos screw terminals and those just showed up in the mail.  I'll let you know when I have your parts sorted and you can drop by.

When will the Alctron HT-11A bodies be available again?
(It seems they are sold out for a long time.)

Hi guys, newbie here.
I've made clone type kits in the past (La2a's, Neve 1073, Pultec Eq etc) however I've not attempted a mic.... Until now.  Since giving music a break whilst working on my house I have now decided to set up a studio... Again!! Must be mad ;-)
I was hoping to make a U87 style mic. I'm sorry for my ignorance here but is there an unwritten rule that one place cannot just supply all of the parts needed in one go? I remember all of this rigmarole with my other projects... Its all flooding back to me now.
I like the DIY building but I hate the amount of hours spent searching the net.
Again I am sorry for my ignorance and would appreciate any advise.
Many Thanks
Brett

Go to the top of this topic, look in white market, research is what DIY is all about IMO!

Hi Pip, thanks for your response, I understand that this can all be part of the fun, but I really enjoy the making part, not so much the sourcing all the parts from all over the place part  :'(
I suppose I was just hoping that there was a one stop shop kinda thing going on by now, maybe there is and I've missed it somehow?
