Hey guys,
I still have an issue with my rimshot, as I told before.
It just brings some loud crackle sound out, like when you are on the power, while speakers are on, or plugging a cable.

I already checked all resistors, most caps and replaced ICs.
Still nothing changed.
I just desoldered the electrolyte caps today, but I dont know how to check them.
The crackle sound is still the same without those caps in the circuit...

I hope someone can help me or just tell me what else I could do.

Thanks a lot,
Jule

Just solved the problem by using the original TR-909 service manual.
I checked all the circuits of the rimshot and a few hours later I figured out that there was a missing connection between two points.
So it was a broken trace in the PCB.
Soldered a small wire on it, now its working.
