Werkstatt – Looking for defect Modules

I posted classifieds and on various groups that I am looking for and buy defect Eurorack modules to learn and study current techniques and how to do troubleshooting. Got a few already and more are on their way – even one from Japan !

So, lots of work waiting for me but hey, it is so much fun to work with real hardware again.

If you have one you want to get rid of just send me an offer me[at] 


Diary of my Journey in Modular Land (22)

Got the Snazzy FX Ardcore incl. Expander offered second hand like new for 50% of the new price, could not resist and bought it. Took only an hour or two till the first program was uploaded and working.
Although there was the usual hiccup with the drivers on macOS it worked ! Even without  disabling the Apple drivers.

Have to test now on new macOS Sierra … Thanks winter is coming and long dark days/nights for  deep sound explorations.

Werkstatt – SSRLabs SM042 Kotelnikov

I made a big mistake here:
Mixed up IC sockets and went crazy cause could not find where to put some component.
My apologies go to Dmitry, owner of SSSRLabs, for saying there is a mistake with the kit.
Had to un-solder and replace the IC socket – took quite some time but got it done !
And finally I lost a capacitor  …

Many, many thanks for your patience Dmitry!


Current state of work on the SM042 Kotelnikov kit. Another evening and hopefully it is done and WORKS !

Still looking for a better Function Generator, Digital Multimeters,  NF Millivoltmeter and other audio measure instruments. A HAMEG 205-3 Oscilloscope is on its way.

Diary of my Journey in Modular Land (18)

Got a lot of work to do in my job with quite some responsibilty.
A bit unlucky last few days concerning audio stuff.

An IC socket was missing from the Kotelnikov kit so had to wait till a box with sockets arrived yesterday. Now I can go on.

Still no clue why the Rebel Technology Stoicheia does not work 100%. Have to wait for an oscilloscope. Easier to follow the signal path.

Bought a sec hand oscilloscope, coming home it did not work properly, was quite a bit  frustrating. At least got an agreement with the seller who refunded half of the price.
Had a hard time to find another at a good price asap. Hopefully arriving next week and praying that it really is properly working.

Worked on new patches but nothing really worth to share yet.
