If still available, I would like to buy the 1157 Mini ADSR and 1145 VCLFO from you. I am located in the Netherlands.

I got some extra PCB/panels left over, if you are interested. Delivery to Germany:
1x KOSMO polykit//kosmo-spring-reverb-driver (panel=pcb, needs a separate spring reverb tank, I took mine from old guitar amps)
3x KOSMO polykit/kosmo-multitool (PCB+panel)
Each 10€ or in exchange for other PCB.
I sent you a private message
It’s my turn to offer a few PCBs for trade. Currently available:
- Kassutronics/Analog Output Precision ADSR. Main PCB only. I was successful in kludging all the controls behind a custom panel, so I only needed the main board. This way you can use any footprint for the A1M potentiometers which I had trouble sourcing. See my post here.
- EFM Dual Voltage Processor. Single PCB. Can be used behind a Kosmo or Eurorack panel.
- Moritz Klein (Ben Jiao version) Diode Ladder VCF. Main and control PCB set, no panel. Eurorack format but I was able to fit it behind a Kosmo size panel. See the picture below.
- Gerbster Echo/Reverb (Synthrotek’s Echo clone). Single PCB, no panel. You can fit this behind a Kosmo size panel, but the board has a couple of issues. See the discussion here.
- Ian Fritz simplified matching transistors circuit on a small PCB. See the discussion here.
I am primarily interested in single boards that I can kludge behind a custom Kosmo panel so they could be Kosmo, Eurorack, or some other format. Can be anything really, just let me know. I don’t really expect that anyone will be hugely interested in trading the last two I have on offer, so I will happily throw them as extras in another trade if you’d like to!
The national post here is particularly affordable for a small letter, so I have no problem sending these anywhere in the world (Universal Postal Union country members).
Hello Kostas and everyone,
I don’t know if you still have some PCB’s left to trade… But I’m interested in your VCF and Dual voltage processor.
In exchange I don’t have much (most of my PCB’s are still “work in process”)… But I made a Joystick controller (schematic from Befaco) and a EFM Moog Taurus VCF.. Otherwise, I have 4 PCB + panels (eurorack) for the Erica Synths DIY polivoks EG and VCA (the VCA’s panel has just one problem, the label of JLCPCB was printed on the front).
Hope you can find something of your interess, as for anyone else !
Oh and by the way, for the shipping, I’m in France
I sent you a direct message!

Hey all, I would have a novation circuit (original) 50£ a volca sample (original) 20£ and a toneport UX2 10£ to sell. Happy to sell to anyone from the forum that could pick-up around Stockport.
Would anyone in Germany/Europe be interested in my version of winterbloom castor and Pollux (eurorack format, not kosmo)? SMD is presoldered apart from the LEDs and I can flash the firmware (it’s a bit crazy procedure, at least for me).
There are 3 caveats:
- I used wrong values for two of the cv input stabilizing caps, so I had to desolder them. With them there is always slew on
now that they are removed, everything works, seems like they do not need stabilization… - I could not find the correct ESD protection diodes at JLC so I left them out. Who needs voltage protection anyways? (they can still be added if you find them)
- The mixing pot is the wrong direction. You have to do the bendy thing with the pot, reversing the outer pins. But I guess everyone in this forum knows how to do that!

Damn. Just bought my first eurorack case but I’m in the states.
Anyone in the UK have extra Kosmo format PCBs, Panels, etc.?
Does anyone need/want to get some ordered?
I am in particular looking for some AO modules, and open to nearly anything 
Selling spare PCBs (together with programmed controllers) of my AUTOTUNE module, which I developed to gain control over my good sounding but instable Moog 901 VCOs €50.00 plus shipping.

Details below on a few boards that i have extras of - I can send them in the UK, and ill be in the US in a week or so, so I can send them there as well if you ask me before I go. I am open to trades or anything you want on top of the postage cost. I dont know about sending to the EU, but I can try.
I have 4 extra Synth Mod checker boards, and some chips/displays/etc. I modified the layout to put 1/4 in jacks instead of 1/8 in. It works pretty well. I also have the kicad files and pcb mfg files if anyone wants those.
These let you generate varios clocks, gates, CVs, and Audio frequencies, and tune a lot of the parameters for each, wave forms, timings etc. It also has some audio in and gate in analysis. Run off of a ATMEGA644.
I also have 4 of these power cable testers, I also have some extra displays and CD4051 chips for these.
and 4 PLA 2216 clone 16 Channel logic probe board for Rigol scopes with logic analyzer capability. These boards have all the SMD resistors and caps, only nissing the pin headers and the SN65 LVDS chips, which I have as well - they are SMD.
Let me know if you are interested in any of these.
