The delay IC is a PT2399 and is easily accessible and replaceable in the center of the lower level pcb.
You will find the IC since the code is written on it.
If you have experience with SMD desoldering/soldering, you can swap it. The IC package is Soic-16.
The IC in charge to handle signal coming in/out are TL072 and powered with +-12V, therefore they will handle Eurorack signals.
It might be though, that the delay IC is not the cause of malfunction.
You can try to fix it, I will try to assist as i can.
Otherwise drop us an email at Koma and at the moment we have availability for non-warranty repairs

Thanks for the reply and precisions. I kind of gave up so did not mind looking for an answer. Listening to old tracks recorded using FK FX that sound quite good, I decided to have a look again.

I will definitely have a look and might try.
Is there anyway I could troubleshoot with a multimeter to find what’s wrong/ which components is faulty.
Since I have 2 units with the same issu, my guess is there is a weakness somewhere / a place it would most probably fail. Any idea?
