Post by: doubleroger on May 13, 2009, 01:53:08 PM
I've looked on your site and can't really see: is there a way to hook up those kits to an already existing (or custom) PSU, in a rack I would make myself?

Those MP66 look awesome, they look like they have that special Gers vintage sound (warm, punchy, wich a little crust in the foix gras range) one would be looking for!
Title: Re: Sound Skulptor professional audio kits
Post by: dandeurloo on May 13, 2009, 03:03:53 PM
how do you mount your tube pre in your rack?
Title: Re: Sound Skulptor professional audio kits
Post by: JPK on May 13, 2009, 03:48:30 PM
To mikefatom :
Thanks for the nice comment. They also sound good :-)

To Doubleroger:
You are absolutely right about the foie gras crust but you must not forget also the Bordeaux effect in the high end.
For sure you can install these modules in your own rack. You just have to provide the ad hoc PSU. I have a connecting diagram available that I will post in the FAQ, in the local forum.

To dandeurloo:
The MP66 tube pre uses 2 slots in the rack. They are mounted like the others on 5mm stand-offs.

Title: Re: Sound Skulptor professional audio kits
Post by: JPK on May 19, 2009, 05:37:38 AM
Yes the Euro value is really painful. But most people here think it's cool because they can buy US products cheap.
Still wondering about the 500 size. Maybe I am waiting for a new extended standard to come out.

Just a bump for Jean-Pierre and Sound Skulptor. I built a rack with four of his modules - two MP32, an MP73 and an MP12. They are beautifully designed, fun to build and they do sound great. I plan on building another rack with two MP66 in it.
Those of us who enjoy DIY and kit building are very lucky these days to have so many wonderful choices, from so many talented designers.

A few preview details are available here:
http://www.soundskulptor.com/uk/sts.html (http://www.soundskulptor.com/uk/sts.html)

We are also considering creating a mini kit that would exclude case, PSU and panel components such as pots, switches and connectors.
The advantage for DIY’ers would be the ability to make their own casing as shown in the 2 examples below.
Please let us know if there is some interest...


hi jp, interested of course!!

Those tape sim boxes look and sound GREAT!  I'm definitely interested in some kits.  And I'd probably rather have them in my own case.  Nice job!

Post by: JPK on February 08, 2010, 05:40:14 PM
Thanks for the feedback.
Just to make things clear, the vintage unit as well as the 4 channels unit are just examples of what can be done and they won't be available as kit. Those who want an original design can use the mini kit and create the case they want.
Regarding the pricing, still working on it, it won't be long now.

what kind of power supply does it need? I'm thinking the mini-kit would be great for 51X rack with a custom L-bracket. If it fits, of course.

Hell, you could probably buy a MCI JH-24 for less than what you'd spend on 12 channels and you'd get an extra 12 thrown in for free. :)

Oh, and this part of your site is great ! http://www.soundskulptor.com/uk/calc.html

Media costs = 1 or 2 reels of tape that you re-use.
Maintenance on my refurbished JH-24 = minimal,
they don't break unless they're moved around a lot or have
30 year old capacitors in them.

Unlimited possibilities for sound sculpting + cool factor = PRICELESS.  8)

Cool project none the less.

That's what we at work call a "happy day scenario". I'm sure it works like that in a small project setting and there's no one calling at 4am to get the thing calibrated. But anywhere else reel to reel tape is never low maintenance.

Not to beleaguer this, because your points are valid if your using the analog deck as your primary recording medium.

What we're talking about here is using analog as an effect, not as a primary way of capturing audio.

My point is simply that you could invest the same or lesser amount of money to get this effect and as a bonus you get the real deal, not an pale imitation. The multi-track deck becomes an FX box, nothing more.

You won't be getting called to fix the analog fx's box at 4am, I assure you.   8)

Yes, That's also what I'd do when I'd buy a serious taperecorder again. A few years back I bought a cheapo Fostex 4 track tapedeck, just to check what I could do with it for use as a tapesimulator (or recording in Daw, reamping to tape). Unfortunately, the beltchain of the Fostex was broken, so the test never happened, haha.

However, as a recording medium.... : I had a couple pro Tascam Direct Drive tapedecks in the past, beautiful sound, but they broke down regularly.... A Horror ! That's when I decided to switch over to DAW recording.

The prices have been finalized and are shown on page 1.
We will make more audio samples in the future.
A 500 series will be done if this product shows enough interest. The current PCB won’t fit in a 500 rack.

Hi Jean-Pierre,
I assume these take up two slots in your standard rack, as does the MP66, is that correct? Using your standard power supply and DIO? Looks really nice. I would be in for a four-channel setup.

Hi Keith, how are you doing ?
The STS is different from the Skulptor preamps : different case, different PSU.
I took this direction to achieve the lowest possible starting price.
Now the good news is if you want a big case with large vu-meters or a 4 channels 1U rack or an 8 channels 2U rack or anything else, it is quite simple to do: Change the front plate on the full kit and you get a 19" unit. Use a 1U rack case + 2 full kits (case less) and you get a 4 channel unit. If you are a little more comfortable with DIY you can make your own case design.

Kit for stereo sounds interesting... :)

How about a more comprehensive set of audio demos? I'm eager to hear more. The idea is very interesting, but the current demo is simply too narrow scope.

Post by: zayance on February 26, 2010, 08:49:21 AM
Yes i tought the sound examples were too narrow also and a little too extreme for the first example, could be nice to have a small palette of sound, with/without, a little process, more process, and extrem process, in all of the different tape speeds, and all in 44.1Khz 24bit at least, so could be heard on each one systems, it's maybe asking too much tough, because none of the projects here have sound exemples, but like Igor wrote on his white market, well sounds good when done with care and good components, but still could be nice to have more exemples, if it's really worth it (and i think it is), would make it even more demanded, don't you think? But maybe too busy now, doing all the process around releasing these...

But that's a great job, and a really nice project, really.

Exactly.
I posted a link to this on another forum and first reaction was that there was only 1 sound example...
This is indeed a very good product at a very competing price, especially when compared to the ATS-1 tape simulator from Anamod.
Title: Re: Sound Skulptor professional audio kits, Coming soon : the STEREO TAPE SIMULATOR
Post by: zayance on February 26, 2010, 03:32:52 PM
True ATS-1 is really expensive, i actually wanted to test drive the machine, didnt found the time right now, but looks like a beast tough, but dunno if the technologie will be timeproof  ???, i mean analog computing, with different cards that can be installed...., i'm not very experienced in electronics, but this must heat a lot no? i have a picture found of the guts of the machine from sound on sound, looks like good quality, (toroid could have been out the box tough for that price, or mumetal shielded or whatever). There were a lot of doubts on that design actually, but seem to be very good sounding machine from the samples done by a user on Gearslutz.
Anyway, i don't know why companies these days (beside Soundskulptor of course  ;D) don't take a little time and spend or work with a studio to get us some sound examples (yes even sound examples could be mixed up to make you believe), i understand that in a marketing point of vue, this can narrow the people buying that stuff, and don't get it also, no offense these days most of the gear out there is marketing, quality is for people who search the right way, or build their stuff (thumbs up to Prodigy and all of you guys  :)) or have the big bucks, and even there sometimes you end up on some crazy things (thanks for China  ;))
Not giving samples could reveal the scam also, but if you're confident about your stuff, then providing sound examples is the best way to get your job advertised, whatever will be the tastes of the people around, taste is like colors, nothing to discuss about, it's totaly personal....
Anyway can't wait the sound examples to be there, i'll be interested in that gear also.

aren't sound samples very "subjective" ?
this is a provocation question, I know.

you like it, someone else will say what the f**k is that.
but the unit might work for the other ones as well, with other settings.

however, if it will be released in any 5XX format I'm in to try it out myself.

Yes very subjective, like i said in french there is a phrase that says, the tastes and colors don't get discussed or something like that, but you get the point, it's just that since it was on the website to listen, i believe some people would have liked at least some more, that's all.

Personally, i've blended both the dry and wet samples together at various ratios and have found some really realy nice sounding combinations (to my ears, at least) that I don't think I could get with my current plugin arsenal. These sims are high on my to-buy list, but a 500 format product would make that purchase decision even easier ;)

I will build it in a 1u 19 inch case with stepped switches so i don't need pots.

Just wondering about the VU leds, how far away are they from each other? Asking this because i'm going to do a shaeffer panel with the led VU bars.
I will build the sts in a 1ru case with 2 deck 24steps in/out attenuators, so just one control for in and output, so no left/right but stereo.
Do you have a panel file available maybe?
Title: Re: Sound Skulptor professional audio kits, Now shipping : the STEREO TAPE SIMULATOR
Post by: JPK on March 15, 2010, 09:05:01 AM
The STS is 1U high but not exactly 1/2U wide.
To make a 1U rack case, it is possible to replace the current front panel by a 19" wide one.
Below is a Front Panel Designer file that will do that :
http://soundskulptor.com/download/sts/sts1-frontplate-19.fpd (http://soundskulptor.com/download/sts/sts1-frontplate-19.fpd)
From this file you can also see the panel cutout needed for the led meters.

If you want to mount 2 STS in a 1U rack case, use the case 1SL01170N here :
http://www.modushop.biz/ecommerce/cat066_l2.php?n=1
Then drill the face and back plates accordingly to these Front Panel Designer files:

*** Warning : Not tested yet ***
The STS case is a little wider than 1/2 of a 19" rack.

The LED meters are included in the mini kit.

My kit came in today, looks great! the board is bigger then i expected and looks cool! :)

Just wondering, what is the purpose of glueing the diodes D3/D4 to the transistors and what will happen when you just solder them in? is it because of heat measuring or something like that?
Title: Re: Sound Skulptor professional audio kits, Now shipping : the STEREO TAPE SIMULATOR
Post by: JPK on March 19, 2010, 11:58:26 AM
The diodes are used to set the idle current in the power transistors. If they are not tied to the transistors, a temperature increase will increase the current, which will increase the temperature and finally cause a thermal runaway, blowing the transistors away.
When the diodes are tied to the transistors, an increase in temperature will cause a current decrease which in turn will lower the temp. The result is temperature and current stability.
Title: Re: Sound Skulptor professional audio kits, Now shipping : the STEREO TAPE SIMULATOR
Post by: dagoose on March 19, 2010, 01:27:46 PM
OK, cool, so basically just as i thought.  :)
Makes sense to me.
How hot will the transistor/diode run in practice? can i use a gluegun to glue then together or will that melt because the of the hotglue temp? i love hotglue you know  ;D
Title: Re: Sound Skulptor professional audio kits, Now shipping : the STEREO TAPE SIMULATOR
Post by: JPK on March 19, 2010, 01:52:52 PM
I would not use hot glue. I doubt it is a good thermal conductor and it is not very well adapted to very small works. I'd recommend a drop of super-glue (cyanocrylate).
Title: Re: Sound Skulptor professional audio kits, Now shipping : the STEREO TAPE SIMULATOR
Post by: dagoose on March 22, 2010, 07:44:10 AM
I glued the 1n914's to the transistors with superglue, wasn't that hard indeed, have to put on some caps, inductors and then the maninboard is done.  8)
The only thing is that 'm waiting for the 24 steps switches to come in (from Finland) so i can have it done with stepped in/outs but i have enough pots to test it, might also come in handy to see how they react so stepped switches are easier to set right.
I will also have a hardbypass (relaybased) instead of the onboard bypass.
I think i will use a 317/337 based PSU for it, i like them more then 78/7915 psu's and since i have a board left for that it's quite easy to do.

Still wondering about the 1n914, why did you go for the 914 instead of the 1n4148 since these are basically the same (google says it's the same) instead of the current it can handle.
Or is it that lower current of the 1n914 that is used for the temp/load compensation? i know.. i'm curious.  ;D

This picture shows a prototype of the EQ573.
It is a 1073/1084 EQ module with extended frequencies, to be inserted before the the output stage of the MP573 preamp with a 3 wires side cable.
It can also be used as a stand alone EQ through its electronically balanced line input and output stages.

This project is moving forward very well.
The design is finished.
We are currently purchasing the various components to build the kits.
I expect it to be available during summer.

They sound different ;-)  But I still promise to post sound comparisons up soon....  I'm just so freaking bust at the moment....

Here is a link to the Robots and Dinosaurs Sydney Hackerspace: http://robodino.org/ (http://robodino.org/) and if you contact them with those details, I'm sure they could arrange something.  I actually did DIY red anodizing of a 1u rack panel there today, so there's all sorts of stuff you can do there.

Post by: etheory on September 26, 2011, 10:33:25 AM
I'm going to have to take my previous statement back.

Running from a line source into both pre-amps ( with the line out set to output -21dB into both of them ), then using both pre-amps to get back to line level is an amazing experience.

I realize now how much my ears completely suck, and how much working with these pre-amps will improve them.

BOTH the VP26 and MP73, in that particular application, sound like wire with gain, if not run into their clipping range ( and what a huge range it is before they get there.... ).

Honestly, I can't find a hint of signature on either aside from the fact I like the sound of both more than the original signal.  There is something I can't identify there that both do to the sound.  The clarity that is partially hidden in the digital source is revealed and smoothed and gooed together even so slightly, yet, seemingly in contradiction, but not; the transients sound more in your face, the bass has more presence, blah, blah, blah.

But both of them seem to do "basically the same thing".  They make audio better, even though it's a tiny tiny amount of better, it's still better.  As for the difference between them, so far, I can't hear one, that's how insanely good they are.  No noise, no hiss, no background noise, not even any distortion that I can hear - truly and honestly, they sound like gain producing cables with some magic sauce in there too.  I'm gobsmacked....

I'll have to rethink that summation after hearing them through a microphone with a live vocalist ( which I am doing this weekend ), but with the only source I have, it's too hard to split them.

For someone who has been used to upper-level consumer gear previously, these devices are both a total revelation ( insanely awesome ).  I can't recommend either one enough.

Once you put them into the clipping range, the difference to me is that the VP26 sounds like there is more going on in the mid-range during clipping and for the MP73 that there's more going on in the low bass and hi treble, with the mid-range largely surviving in tact.  I can hear in that application why people say that the VP26 is more of a rock pre, as you can hear that in the clipping range.  But I won't really be operating them in that region anyway.

I know that doesn't help, but it's what I heard.  Clearly you need an opinion from someone with better ears ;-)

Very interested in getting a pair of EQ573 kits... (still loving my STS by the way)

Would these eqs be nice on my master fader? Anyone using them like this? Or are they more suited for single channel type stuff?

The 1073 was designed as a channel pre and EQ, with lots of available boost and cut but for sure you can use it on a bus, as long as you use it moderately.

The new products will only work in the new rack.
Now, the only difference between the two racks is in the connector and it should not be too difficult to make an adapter with a little piece of breadboard.

About how long did it take for a package to get to your home in the US? For those of you who live in the US and ordered something of course. I was under the assumption that once it left France, tracking would be unavailable so I'd be just patiently waiting after that.

It generally takes no more than 10 days. You are right, the tracking info always freezes at the french border. It wakes up again once you've received the package.

If no resistance means infinite resistance then you're OK. The problems come when the resistance is too low (like in a short).

Interesting... This was an extremely easy build and I didn't have any problems... I don't have any voltage though. That's why I thought the resistance was wrong. I don't show to have any voltage at TP3 and CN3. What should I check?

For any of you who may have read this, or for anyone who may stumble upon this in the future, my problem is solved! I thought I would use this forum to leave Jean-Pierre alone as much as possible, but he went above and beyond to help me solve this with a series of emails. In the end, it was my own oversight that caused the problem. I had switched two yellow capacitors with two yellow resistors that looked an awful lot alike. Small, round yellow disks. Any idiot could've done the same, right? So, for those of you interested in this kit, get it! It really is an easy build and things couldn't have gone smoother. Just make sure you don't have your head up your ass like I did. Thanks to Jean-Pierre as well for the emails and his knowledge of his product. He was able to help me figure out the problem and got me on my way to a very cool preamp! Couldn't have asked for more.

Post by: useme2305 on November 10, 2012, 11:35:34 AM
does the eq573 run on single rail +24V?

i have two ez1290 boards and want to integrate the eq573 with each ez1290?

where would the eq573 best be snuck into the ez1290 circuit? between the two gain stages of the ez1290? or directly before the output tranny of the ez1290 circuit? i guess that i'll have to omit the balancing and de-balancing stages of the eq573 when doing this?
Title: Re: Sound Skulptor: Preamplifiers, Equalizers, Tape Simulator, rack and '500'
Post by: JPK on November 11, 2012, 04:30:01 AM
The EQ573 runs from the lunchbox standard +/-16V, but internally it runs on +24V. The local ground is shifted by minus 9V to achieve this.
It would be easy to return to a 0/+24V supply by not installing a few components but this would exclude the use of the I/O stage that is used in the stand alone mode. It would require that the eq is inserted into a 1073 kind of pre, after the 2 preamp stages, before the level pot and the BA283AM output stage.
I am not familiar with the ez1290 but if you could point me to a schematic diagram, I could tell you where it can be inserted.

Post by: useme2305 on November 11, 2012, 07:28:48 AM
here are the schematics of the ez1290 taken from martin adriaanse's assembly guide.

by your explaination the eq573 would be perfect for fitting into the ez1290 preamp. i think i'll deffinitely go for it if i can figure out how.

Post by: JPK on November 12, 2012, 08:37:04 AM
Sure!
The only restriction is that you won't get the clip LED indicator working without a negative supply voltage (-15V minimum).

Awesome! I JUST finished mine! It took me about 12 hours or maybe more. I went slowly/carefully. And I was able to calibrate it without a hitch!

I haven't passed audio through it yet to hear it, but I will in the next few days.

Kudos to Jean-Pierre for an EXCELLENT kit that is just absolutely top-notch in every way. It's a beautiful-looking piece of gear, and if the hype holds up, it's gonna sound grrrrreat!

If you're on the fence about a kit to get for your studio, I would HIGHLY suggest you look into the SoundSkulptor line. Exacting attention to detail, gorgeous fit/finish, premium components and world-class design. I couldn't be happier with the kits I've put together from these guys (an STS as you know, an MP73 and an MP12!)

Thank you so much Jean-Pierre!!! Believe me when I say that this won't be the last time I'm raving about one of your products! Got the MP573 and love it. Next will be a pair of your EQ573s and an additional MP573. But this has to wait till next year... Until then you could think about adding a compressor (Neve-Style?!) and / or API-style EQ (560?!) to your range of products ;D Would love to get some of these in typical Sound Skulptor quality!

Agreed, we take a hammering in North America!

So build the kit slowly, like I did. I put together the case and one module, and a year later, added another module...you spread out the "pain" and pretty soon you've got some killer pre's and you're a happy camper!

That's what I did anyway. And, I did have a lot of questions even though the docs were very very good. Jean-Pierre has been a saint in responding not only very quickly, but kindly and with accurate and helpful info/assistance.

Hi.

Need to get a 1176 style compressor (or two!) at some point and was impressed by the options on the CP 5176. The product page includes most details, but there are a couple of other things I'm curious about:

It's 500 compatible, so it's presumably using the +/-16v rails. What does it operate at internally? Obviously I'm asking because there's another 1176 around that operates off +/-16v too, and converts to +30v internally, so just curious (though I'm currently leaning toward your unit due to better options).

Also, l noticed that there is a button that adds THD for an approximation of the "A" variant. Without that button, which variant does this unit most closely resemble?

Anyway, heard great things about your kits... ;)

Cheers,

Kaz

Post by: JPK on September 24, 2013, 02:44:14 AM
Hi Kaz, thanks for the kind words.

The CP5176 creates a single ended +28V power rail out of the +/-16V to power the variable gain stage.
Because it uses a DOA, the output stage is normally powered in +/-16V.

The variable gain stage is based on the 1176 - REV D. The 'Dist' switch unbalances the FET distortion cancellation circuit and produces a few % of second harmonic distortion.

Not only that, I discovered recently I like the Stereo Tape Simulator so well I thought I would track vocals right through them...they naturally compress and I didn't even end up needing to use my other compressors. Awesome sounding! Liquidy, gooey, warm, golden, saturated tape goodness with smart controls and sharp-looking panel.

Thanks again Jean-Pierre! Hope you make some more new things I need...because I'm a DIY guy and I NEED to DIY more of your stuff!

i've been using my MP573 on a few sax sessions recently and it sounds AWESOME! smooth and warm, it really tames the brighter mics in my locker like the AT4033 and AKGC535. nice on everything else as well. Great work JP!

I'm digging into my build of the CP5176 and I've discovered that my kit came with a 331pF ceramic capacitor for C16 which is spec'd as a 330pF film capacitor.  I'm almost willing to assume that this is an acceptable substitution but.... better to ask than be sorry.  Anyone here know if it's cool?

Thanks

Not an expert on this build (or any other!), but my kit came with the same spec'd part and it's been running fine.

Sometime capacitors have slightly different markings, of the format xxy, where y represents the number of zeroes to add on to the xx. This means 331 expands to 330, if that system is in use in this case. As I said, I'm no expert so I can't say when the system is employed and when it isn't so I might be wrong in this case.

If the forementioned system isn't being used, then the error introduced is only 1/330th of a picofarad which is well within the normal 5% tolerance of most of the capacitors we (groupdiy'ers) use in our (many other unrelated) builds anyway (obviously the lower and upper bounds for the component would be affected though).

Of course film vs ceramic might be more important, but I don't know anything about that...

Hope that helps.

Please check the "important notes" document in the kit box.
The originally spec'ed 330pF Wima FKP02 cap has been out of stock for 10 months and will probably remain forever.
We have replaced it by a high quality COG ceramic cap with no measurable effect and no sound change.

By the way, any plan to release the 176 comp on the 1U rack system ?  ;D

Thank you for the nice comment.
Adapting the CP5176 to the rack system would require 2 slots because of the number of panel controls. This is not very desirable because it doubles the per module cost. So, while no final decision has been taken, we are leaning towards the "not doing" direction.

Hi!

I built a MC624 a couple months ago and I am having issues with some of the combine/compare buttons. It has been a problem since the beginning, but it has worked great as a i/o router, so I have not bothered to address the issues.

When I select Mono, it mutes the signal entirely, and the Diff button solos one of the channels. This does not happen on headphones, so it must have to do with the signal going to the outputs. I am guessing + and - signals are getting flipped somewhere in the routing, but I will see if you have any thoughts. Please let me know. Thanks!

(and all that said, the build was easy and I'm very happy with the quality of the unit!)
Title: Re: Sound Skulptor: Monitor Controller, Professionnal Audio Kits
Post by: JPK on January 22, 2015, 09:03:40 AM
The mono and diff switching takes place before the headphone/monitor fork.
Make sure that the balanced/unbalanced setting is correct for the input. An unbalanced signal on an input that is set balanced would not allow the diff switch to work.
A muted mono could be caused by a non working U3. Check supply on pin 4 (-16V) and pin 8 (+16V), relatively to GND. But it would happen both on the headphone and monitor outputs.
Title: Re: Sound Skulptor: Monitor Controller, Professionnal Audio Kits

Well, I just discovered that my interface has impedance balanced i/o.

Hey guys,

I did a time lapse video of me building the SK25 discrete opamp including making and fixing a mistake. Maybe this will help beginners in doing this kind of build. It's not difficult but simply a lot of parts in a very small area:

Post by: JPK on February 12, 2015, 03:02:10 AM
Excellent video. Thank you.
Do not forget, at the end, the little drop of glue that thermally links the 2 diodes to the heatsinks. They will prevent possible thermal runaway.
When un-soldering a component, if you can't heat all the pins at the same time, it is always safer to sacrifice the component and remove one pin at a time. Otherwise, the risk of breaking the via that connects the top and bottom pads is very high.
Do you need a replacement inductor?

Same here.  One obvious difference is that the original MP66 has two tubes, whereas this MP566 only has one. Not sure how that would affect the sound. However, I'm sure that, like all Sound Skulptor offerings, it is a great piece of gear.

Hello all,

I recently purchased and assembled the MC624, great kit! It was well packed, easy to assemble, and looks great! Thanks so much!

However, I've run into an issue during testing and was hoping someone could help point me in the right direction.

I got to step 4 in the testing guide, the digital test.  The level encoder knob works, the 7-segment display functions normally.  The input LEDs, however, behave erratically.  Some don't light up at all, others only light after multiple presses, some light but then revert to the previous selection.

The output 1 LED is lit, but the other switches won't light.  The switches in the middle (Mute, Dim, etc.) do not light at all.

I think the switch soldering and connections between front panel and main PCB are good, but i don't have a lot of experience with digital logic.  Anyone have any thoughts?

TIA

Hi Idiophonic,
Double check that the resistor networks RN1 to  RN7 are inserted in the correct direction (white dot on one side). If, eventually, one would be in the wrong direction, do not  try to unsolder it . Slash it first into 1 pin pieces, then remove the bits.

JPK,

Thanks for the prompt and accurate reply.  I indeed had RN2 and RN3 reversed.  With  a professional desolder station they came right out, went back in, and the rest of the testing/calibration went smoothly.

Thanks again for the prompt reply and the great kit! Cheers!

Hi Jean-Pierre,

After a few years of happy tracking, my MP12 suddenly has super low output. What's the first thing I should check before doing major troubleshooting? Box has been mounted and not moved and has worked fine for quite a while....It seemed the output started dropping and I needed more and more gain for the same mics, until it's very low now.

Thanks much,

Mike

Hi Mike,

Check the output pad potentiometer. Is it working smoothly from min to max ? With the pot at max and sending a constant sine on input, you could measure the AC voltage on output and compare it to the AC voltage across RL2.
Check the supply voltages on TP2, TP3 (what voltages are you using?).
Are you using the servo to null the output voltage (what DOA are you using?)?

Hello Jean-Pierre,

Just got my Sound Skulptor kits in the mail and I am busy building them!  I've got my first MP566 assembled and I'm currently running through the testing sequence.  So far so good -- got 224 volts for the High Voltage check (step 3), and nothing's on fire, so I must have done something right.

Moving on to step 4, I'm testing the heater voltage.  The test says we should expect +12v between V- and TP8, but I'm only seeing a solid 10 volts.  The unit's been on for about 10 minutes now.  I thought it might rise a little as it warmed up, but no -- sticking right to +10v on the nose. 

Is that "around" 12v for purposes of the test?  If I'm undervolt, how would I begin to troubleshoot that?

Thanks!  Looking forward to using this preamp!

Matt

Hi Jean-Pierre,

on my MP566 the same solid 10 volts between Pin 4 and 5 on the tube socket. This is 2V underheating. Ok i use a cheap SM-Pro Rack ::), but it have 320mA per slot.....
the preamp sounds great with high gain and incredibly low noise floor.
in microphone builds 2V underheating have a drastic effect of the complete mic operation.
Have the 2 Volts underheating a negative effect in your MP566 preamp?

Best
A.

Awesome !!! I want two of these...!
 Are the in and out pots stepped for easy stereo matching ?
About a year ago I purchased the MC-624 kit and all I have to say is that it'is a fantastic monitor controller. I couldn't be happier!
I 'm sure the tape simulator isgoing to be killer too.

Got the TS500-kit the other day. Haven't put it together yet, it will be my weekend project. But I must praise Sound Skulptors and J-Ps extremely fast service! I ordered (and paid) at roughly 9 am Monday morning and on Tuesday afternoon I got the kit in my hand! From the south of France to the north of Sweden in just 31 hours. A+++!  :)

That's my experience too: Sound Skulptor has been extremely nice little company to deal with! A+++! Excellent customer service and treatment IME. Please slipperyflax, keep us informed how these things sound when the time comes (ie. when you have assembled the kit.) These little beasts are super interesting!

A few questions to the designer himself too.

I was actually just about to order a pair of RN 542 units when the TS500 was released. So I started to hesitate...

The specs seem to be very similar on the paper: bulky trannies, constant current driven tape heads etc. I've seen the guts of 542 and they even look pretty similar.  I suppose that there's quite a lot of inspiration taken, although I greatly doubt that a mere copy or clone has been the target (ts500 is your sts successor, right? :)

Just out of curiosity: has portico 5042 and 542 affected to ts500's design? How would you describe the similarities and differences between your ts500 and RN 542? Did you want to capture some of 542's sonical charm and sound to your ts500 too (and hence the transformers)?

Hopefully my questions and observations don't feel derogatory, they're definately NOT meant to be like that...

Oh, and one nitpicking question... What trannies are you using? I can't regognize the brand. Some esoteric custom wound stuff, allowed only to the chosen few? ;)

Assembled, all setup and just tried it on lead vocals for color. Love it!  8) Although.. I'm the kind of guy who hasn't experienced real tape machines, I just like to put the plug-ins on everything to simulate it. This IS a subtle little box  but and don't do drastic, except for drive which it does beautifully to my ears. I am very pleased so far and now I'm gonna go try it on a mono mix! (will get another one in a month)

Hi,

Can anyone help me with a Sound Skulptor EQ573 kit I just built please?  I am new to this forum so this might be the wrong place, if so sorry.

I have just powered it up to test via XLR switch setting and the low shelf does not seem to be working, or only marginally. When I switch from  to bypass the whole low end picks up but when I switch back to XLR is all  goes tinny again. A frequency analisers shows the low cut to be working and I can hear that the mid and high are working when switched in and boosted/ cut but low shelf seem almost none existant even at the extremes of boost and cutting.

Where should I start to look for a fault?

Hi Mark!

If I were you I'd start a new thread in the project specific discussions, and there filters/equalizers. Start a new thread there and ask for help. Although there might be a dedicated 573eq thread somewhere, I'm not 100% sure...

As far as your topic is concerned, unfortunately I'm not able to help... But I suppose that everybody will suggest the basic troubleshooting first. You know, the usual suspects: how's your soldering, are all the components in the right places, orientated right etc. Quite often the problems are due to some silly build mistakes. I just made my gssl smoking spectacularly, and it was due to a n op amp that was installed backwards.... Dumb, but it happens! :)

Post by: Phrazemaster on November 06, 2016, 02:53:22 AM
Just a question, was the original STS prone to clipping easily? I built 2 units, they are lovely, but I can never turn the gain past about 1.5 or 2, otherwise I get bad distortion on either left or right. Of course yes I can turn up the gain and turn down the output, but I still get distortion. If I leave the gain very very low, I also have to turn the output up to high to get decent signal (makes sense), but then I'm barely able to use the unit.

Any ideas JPK? I know I was very careful in the build, it's just I can hardly engage the unit without having distortion.

Thanks,

Mike

Hey,
Short question.
Do I really need the Nylon washers for the Carnhill VTB9045, cause when i place the nylon washers between the transformer pcb the screws are too short, without the washers the pcb attach perfectly.
Hope somebody can help me
Title: Re: Sound Skulptor: 500 series Tape Simulator , Professionnal Audio Kits
Post by: JPK on January 30, 2017, 02:36:51 AM
The washers only have a mechanical purpose. Because the transformer surface is slightly recessed, the washers are leveling it with the metal envelope. There is no electrical need for them. If the screws are too short, you may just leave the washers out.

When powering off the unit, there is a pop at the output. Is this to be expected? Or is this an error?

Thank you.

Hi JP,
I'm having an issue with an MP573. I can't get the bias to change. I'm only getting .015V at TP4.
I'm only getting 1.08V on the Q4 side of R42.
I have swapped out Q6 and there's no change

Any ideas?


I had the red and green output transformer wires crossed! Ooops!
Working perfectly!

Tell me, when it comes to these kind of optos that's used here (can be seen at step 11 in the assembly guide http://www.soundskulptor.com/docs/la502-assembly-guide-01.pdf ), is there any need for a matched pair when you want to have a stereo pair?

The opto-couplers we use are fairly consistent and there is no need for matching as long as you stay with moderate compression levels .

The CP5176 Slam mode recreates the 4 depressed buttons mode by setting the sidechain gain, threshold and FET bias the same way.

Thanks JPK. I understand how it would normally be implemented with a DPDT toggle but just confused how you managed to do this with a spare step position on a 2x6 rotary? This would typically require 4 poles to short 4 points within the ratio circuit, can it be done by only shorting two points?
Title: Re: Sound Skulptor: Pre's, Compressors, Tape Simulator, Professionnal Audio Kits
Post by: JPK on March 31, 2018, 03:23:06 AM
The rotary switch is 2x6. So one contact manages the gain and the other one does the threshold and FET bias.

Pres went through test and setup some time ago. They are Rev1.3, circa 2013. Pres were working fine with a dynamic mic and also the Hi-z input.  This is the first time I tried phantom power with them with microphones actually hooked up.  I wonder if the problem could be with my patch bays...…..
Title: Re: Sound Skulptor: Pre's, Compressors, Tape Simulator, Professionnal Audio Kits
Post by: JPK on August 21, 2018, 03:12:34 AM
There is normally no connection between R21 and the 48V. But R21 is close to the 48V switch so I would check there is no unwanted connection like a solder bridge or a component lead touching the chassis plate around R21, C6, SW1.
Title: Re: Sound Skulptor: Pre's, Compressors, Tape Simulator, Professionnal Audio Kits
Post by: Spiritworks on August 26, 2018, 01:45:55 PM
I erroneously identified R21 as the burnt resistor. The burnt resistor is actually R1, which is right beside R21 on the PCB and is indeed in line with the 48volt switch, if I read the schematic correctly. I disassembled the preamp and checked for any obvious build errors and solder bridges, etc. , but everything looks OK. The other four of my MP573 pass 48volts throughout my system without any problem. I checked all wiring to/from mic panels to patch bays, as well as the microphone cables I was using at the time. Any other thoughts where to look?

TS500 Question:
I built two of these kits and did the setup/calibration. Everything went well and I installed them in my rack. Ran signal to them in-line from a balanced stereo source ( output of a Tascam CD recorder ) and they work fantastically, as expected. I then used them on un-balanced inserts from a stereo bus on my analog desk ( tip=send, ring=return ) and the output is almost non-existent, even turned up full. Tried all eight bus inserts to rule out a bad bus/cabling. Same result on all eight.  Will this device not work on an unbalanced insert? Does it need a balanced input and output to work correctly? If so, is there a work-around?
Title: Re: Sound Skulptor: Pre's, Compressors, Tape Simulator, Professionnal Audio Kits
Post by: JPK on January 08, 2019, 04:11:45 AM
The input and output of the TS500 are transformer balanced.
It does work on unbalanced in/outs but you must make sure both in and out XLR pin 3's are connected to the ground (to TRS shield).
I believe that this is probably not the case in your insert cables. The shield is probably only connected to XLR pin 1.

Hello all,


have received and built this kit now.
Everything went very well,kit was complete in parts,nothing missing.
Adjustments  were easy,all was close to spot on from scratch,absolutely no issues.
Be prepared the solder nails for the test points need some serious force to put in,so just be careful while inserting them.
It also might be a good idea to let the unit heat up for some minutes,then repeat the balance procedure (which is the last step in adjusting it) two or three times and compare left and right channels.Mine were totally spot on then (within a 0.001VAC resolution of my dmm).
Mechanically everything fits like a glove.
Listening tests on monday in the studio.


Another great kit you have done Jean-Pierre,congrats,keep them going!


Attached a pic of proof,

Udo.

Just finished a LA502 build and try to calibrate it now. I have a question about the trimmer pots that I hope someone here can answer.

On the guide it says turn all the pots CCW all the way for about 20 turns. I think I have done double that count but none of them seem to have a stop. How do I know they have reached the end?

Thanks in advance for the hep.

Post by: kante1603 on June 08, 2019, 08:54:00 AM
Just finished a LA502 build and try to calibrate it now. I have a question about the trimmer pots that I hope someone here can answer.

On the guide it says turn all the pots CCW all the way for about 20 turns. I think I have done double that count but none of them seem to have a stop. How do I know they have reached the end?

Thanks in advance for the hep.

Best regards,
Leon
Hello,


in a quiet environment you can hear them click at their end position.
There‘s no mechanical stop,if unsure just turn them more than 20 turns ccw.
Or measure between the inner and outer legs,one side should show approx. the full ohms value,the other close to zero ohms.


Best regards,


Udo.

Thanks Udo for the clear explanation.  It is very helpful! Just finished my calibration and everything works great.  I am moving onto a second build and soon I will have a stereo pair.

Thanks again,
Leon

The compressors... LA502... CP5176... I eventually want both but can only get one at a time.

Which would you recommend first, mostly for tracking on vocals, guitar and bass? Ultimately I want to go with the tried-and-true Preamp->1176->LAxA chain for vocal tracking.

Of course I eventually want two of the Pultec EQs and the bus compressor for all my 2-bus duties too! But that comes later still...  8) These all seem to be the best bang-for-the-buck on the DIY market today.

I went with the CP5176 and so far.... two thumbs up!

Build was not difficult, just time-consuming... lots going on in there. I had one tiny issue that took 30 seconds to fix on power-up tests but that was totally an oversight and all my own fault.

Now I'm looking for gear to sell so I can buy the opto-compressor.  8)

Hello,

I built the CP4500, everything went very smooth. Now I’m in the process of measuring and calibrating (left side/PCB A). The Setup Guide says:
Quote
Adjust trimmer T1 in order to get absolutely no output level change when switching on and off with the IN switch
However, no matter how long I turn the screw of T1, the output level doesn’t change at all. Also, there’s a huge volume jump when I enable the unit.

My first idea is that T1 doesn’t work properly. I will check the solder pads for cold joints in a minute. But apart from that, what else could be wrong here? Any ideas?

Update: I resoldered all pads, but the problem is still there. I checked T1 with my DMM and it appears to be working. The adjacent R54 also gives me 4.7k as it should. What else can I check?

Tried the same with the second channel now, same behavior: T2 does not change the output level with the module enabled.
