Wow! Yes, I second the request for a price? Also, what would be included in the kit?
Title: Re: Feeler : D47 Tube Mic Kit DIY
Post by: Delta Sigma on January 17, 2018, 12:20:44 PM
I'm in - pending price of course. I'm not in a rush so I'll pass on the prototype as I'm sure there are others who would love to get their hands on it.

Dany, can you comment on the differences between the parallel 408A and EF80X amps? I was planning an EF47 for my next mic but I'd like to know yours and others' opinions on the two amps. Have you tried the two amps with the same capsule and transformer?

I assume from the photos that the kits will allow these options as well as steel tubes.

Will you offer both PCB versions you do now?
And yeah, the  price would be nice to know.

I'm interested in at least two, depending on the price.

I’ve built three MK-U47 kits (sold two, kept one). Those builds were not cheap. I think the total cost was almost 1800 Euros per microphone, including the PSU, cable and everything else. Also the VAT and the shipping costs…

Your kits are even more close to an original U47 than the MK-U47 kits. They look beautiful! But how much will they cost? That’s the crucial question.

At some point, if the cost of a build gets close to let’s say a FLEA U47, I’m not sure if I will be interested.  I hope that’s not the case.
Any way: I would love to build a couple of your U47 kits!

I also would be interested in any opinions about the differences between the parallel 408A and EF80X amps.
I've only used the parallell 408A in my builds so far. They sound very good, but are a bit noisy, I think.

Those look like FleA bodies. I bet Dan has an agreement with them.

Looks beautiful.

I want to use the EF12 tube.

I have all tubes(yes vf14's also)+neumann k47's,etc... I'm also curious about ef12k!
Title: Re: Feeler : D47 Tube Mic Kit DIY
Post by: Delta Sigma on January 26, 2018, 04:06:08 PM
I'm stuck deciding which amp I should build with. I'm leaning toward the EF80X. I realize it's extremely subjective and there may be strengths and weaknesses for each one but...

Dany, can you comment on the differences between  amp / tube choices?

I'm okay with completely subjective terms like "pillowy", "hi-fi", "tubey" but of course am interested in noise (or the lack of).



By the way, I believe Ben started building his Arabellas with EF12s but switched to the Russian equivalents 6ZH8, 6SJ7 and 5693 (not sure if they're all Russian).

https://beesneezmicrophones.com.au/store/6zh8-/-6sj7-/-5693-steel-tube.html

My Arabella had the 6ZH8; it sounded great and was quiet (low noise).

Fabulous job on this kit Dany!!!!  It was a joy to build and it sounds AMAZING.  I built the VF14 style kit.  I have a new Telefunken VF14K as well as a vintage VF14 (non-M).  With the Theirsch Red-line (mylar) capsule and AMI's BV08C Classic transformer.

Here is a folder full of pics of my build:

Hi, No noise problems, it sounds great! Use proper star-grounding in the PSU and join 0V and screen to the mic body.

hi Folks , for those who are building the mic , i have found that putting a small dab of epoxy on the contact tongue inside the headbakset eliminates a resonnance cause by it , as it might be confused with an Mbira instrument from africa,
also using a little dab of epoxy on the screw thats hold the tongue will prevent any shifting during years of operation ,

I am almost ready to release the third batch , i have prepared a little temporary webpage to checkout the offered options,

yes it will work just fine with this psu , all you have to do is to remove power to the relay and bypass the pattern switch or simply cut the WIRE  ;D,   you will need to adjust the string resistor since you draw about 6ma less current on the B+ rail.

Thank you Dan.
Use the 408a tubes and get luck with them cause mine WE408a a quite noiseless.
Transformer is from Srdjan (Moby) and like his BV11 I use in my M49 build I also like his transformer in my U47 clone.

Hi, kind of an old newbie here. I built a lot of stuff but that was a few years ago...
I would love to build a couple of these! But I can't manage to find a build thread. I've built the MK47 before but as I said that was a long time ago and would like to get back up on the saddle,..

When I press the BOM button on http://www.vintagemicrophonepcbkit.com/OrderD47.html
I get to the D-U47FET build thread. So the BOM is the same for these microphones?

I have a couple of Raintons Ultimate Mic-PSU-chassis that I would like to use, but where do I find a PCB that goes with this build that fits the chassi? Would this Zayance's MK-U47 be a good choice?

Also I would like some tips for what to choose regards Capsule Holder, Tube socket, layout etc... I can go with Dans D7 as capsules, so would that be the regular M7 holder?

I rather buy transformers and the other components from Europe since I live in Sweden. What would you recommend?

Kind regards
John

Hi, kind of an old newbie here. I built a lot of stuff but that was a few years ago...
I would love to build a couple of these! But I can't manage to find a build thread. I've built the MK47 before but as I said that was a long time ago and would like to get back up on the saddle,..

When I press the BOM button on http://www.vintagemicrophonepcbkit.com/OrderD47.html
I get to the D-U47FET build thread. So the BOM is the same for these microphones?
this is a mistake on the webpage , i have corrected it and removed the link  all BOM and layout are coming with the kit

I have a couple of Raintons Ultimate Mic-PSU-chassis that I would like to use, but where do I find a PCB that goes with this build that fits the chassi? Would this Zayance's MK-U47 be a good choice?
yes if you choose the VF14 or dual 6028 solution, else i would be able to supply an dual rail PCB for other configuration but it will need some adaptation as per say recalculation and omission of pattern component but you have to figure this part out as i have no documentation on the psu yet

Also I would like some tips for what to choose regards Capsule Holder, Tube socket, layout etc... I can go with Dans D7 as capsules, so would that be the regular M7 holder?
yes regular M7 holder for D7, PM me your wish list and i will have a look


I rather buy transformers and the other components from Europe since I live in Sweden. What would you recommend?

Kind regards
John

Hi all,

I'd like to share some pics of a recent U47 build we just finished up. I am so pleased with the way it turned out and the sound is jaw dropping. I did my best to build as close to original spec as possible. Dan was very helpful throughout the process. I purchased the power supply enclosure and circuit board from him in addition to the all the metal parts for the mic except for the transformer deck. I chose to go with the AMI metal transformer deck and circuit boards. As you can all see that is an original VF12M in the mic that I had in storage for some time. Additionally I used a transformer with NOS laminations from AMI, 10nf vintage styroflex C1 cap, hand selected C2 and C3 caps, Mogami cable, Binder connectors, and Neumann K49 capsule. I didn't spare any expense cause this was gonna be my #1 mic. Enjoy!

Poctop, how is the U48/figure 8 mic's cardioid vs the U47's cardioid?  Identical in your circuit?  I've heard the U48 cardioid doesn't sound as good, but you know how the internet is!

Hi Guys,
i changed my dual tubes to a Telefunken UF14.
Thanks so much Dan for your help with that!
There are just some little modifications with the Zayance PSU pcb and on the mic.
The only problem is the heat.
The bottom of the mic gets really hot after some minutes.
You can’t nearly touch it.
But for all, who wants to go with a UF14, it’s nearly the same circuit like on the VF14.
Will post pictures later, it’s too late.  ;)


Edit:
The heat seams a problem.
Has anyone a original U47 or something with a EF14 or other tubes.
How is the heat ?

Lets Make sure the same number of Watt is dissipated here  ;)
the key of the sounding VF14 is dissipation and underheated tube.
Killing the Watts that is !
Best,
Dan,

The main problem is the heat produced from the filament resistor with the UF14 tube.
I would say it’s something between 7 and 11 watt.
I’ll put the filament resistor in the PSU and take an extra heat sink on it.
Then I will connect the resistor through the PSU cable to the mic.
I don’t have done it yet, but I’m sure it will work. First I need a 7-pin mic cable, the one I used at this times, has just 5-pin.

In the kit I received there was a solder tab and screw in a bag labeled “bell” star ground. Does this need to be attached to the bottom mic where the binder connector is? Is this in addition to the solder tab on the PCB? Thanks

it doesn't matter.
But in the build guide, Dan always send, there is the bottom bell recommended.

Thanks for all the help, everyone. Big thanks for Dan for an amazing project. I'm almost ready to fire the mic up, but I'm having some anxiety about how to wire the mic cable. I'm using a Gotham 7 wire tube mic cable with a Binder 9 pin connector at the mic end and Binder 7 pin at the PSU end. Here is the wiring I was planning to use:
