Finally a new Kosmo module after quite some break. A microphone preamp with phantom power to drive a condenser mic. It’s based on the INA217 amp. PCB is on GitHub in case you need something similar: GitHub - polykit/microphone-preamp: Schematics and PCB for a microphone preamp with phantom power

Hot tip to young players - get a second VCO. I don’t know why I waited so long to build mine and install it…

I always wonder what your panels are made of.
Do you 3d print them?
Mine are mostly aluminium that i found on the side of the road but i’m running out

Oh i never figured they were wood. The varnish makes them look kind of plasticy. In a good way though,they look very nice

The panels look kind of thin in the picture. Are they 3 mm plywood or are they thicker? Have you noticed any bending when inserting a jack plug into a panel or extracting one?
I use 5mm plywood that I sand a little in thickness (essencialy for the pots) , it is quite solid and does not bend

Breadboarding an AS3340. Just getting started, I’ve seen and quantified the PWM frequency shift (about 100 cents from ~7% to ~90% pulse width, consistent across frequencies from ~140 Hz to ~18 kHz). Next to do is to try various remedies that have been mentioned and see which ones work and how well. (not valid, circuit was not right)
