I have a red square pcb set i'm probably not gonna use if you're interested. I seem to recall it being basically a semi-modular prodigy.

Thanks! Been waiting (too long) on replacement FETs from futurelec to do final testing! Hopefully they'll get here soon!

I think jmejia is doing an universal board that will work for all formats, an I think he will sell those.

Mine is 1U MOTM format, but i won't sell them. All the info and gerbers files are free to d ...

Small update here. Our prototype has some issues and is not oscillating. Noise, envelope, trigger and lfo circuits seem to be working.. although the grounding pots don't seem to remove either the nois ...

Great- I'd love to hear a demo - ideally of active vs passive versions Smile

I didn't realize Carsten was selling pcbs.. that's very promising indeed. I wonder what the differences are between his and ...

Lots of great info in this thread - thanks!

Anyone have any insight in to the commercial clones floating around? I wonder if any of them use inductors (seems doubtful), or if anyone knows how they ...

I'm looking for a couple UA776's - if not a couple sets of the full original lineup: УД1208, KP140УД85 and a KT315Г.

Anyone sitting on some?

ouch.

I want one too! Anyone sitting on a pile of em?

Thanks! It's 102.57x83.82 mm (about 4" by 3.30")

Waiting on some parts still to populate and test.

I know it's a delay circuit, I'm familiar with the pt2399. I was assuming this does more or is interesting or different than the other 2399 schematics floating around...?

Could someone describe what this circuit does? I'm having trouble finding a good description anywhere. I found a video - but it doesn't go into much detail...

thnx guys!

Is the bridechamber version different/older than the current 4x4?

I'm not clear on what 4x4 indicates as the elby version looks like a single envelope on board... or am I mistaken?

I'd love to b ...

We should get our protos soon and are planning on testing with +/-12 in addition to +/-15 to see if it works - but nuipb, it sounds like 12 is working fine per xpmtl.

We have a euro connector on th ...

Looks great xpmtl!

Just sent our prototype gerbers to the fab yesterday. Will update once we get a few boards back!

Thanks!

bumping this old thread - these circuits look great! Any further developments or testing done by anyone yet?

I'm thinking about trying the 13700 version...

oh and arnoid - no we are leaving the run generator alone for the moment. Either none of us have gotten it to work right - or it's just not that interesting. It could always be an add-on pcb if someon ...

Sweet! Thanks - I'll give it a shot!

Putting the finishing touches on this pcb now.. shouldn't be long now!

Can someone suggest a resistor change for getting this thing to work at 12V? Or explain an approach to that mod? I'm a bit clu ...

good to know xpmtl - I was also kind of assuming distortion could be intentional/pleasing and am planning on testing both ways as well!

Nice! Thanks!

great looking pcb xpmtl!

waveselector - nice pics! Any chance you could do some of the front panel? Might be nice for panel design!
