Take the pin for VCF CV INPUT in the NJM and follow the tracks backwards. Set EG3 and LFO to VCF int to 0. Now send a sustained midi note from a sequencer and make it loop, then using a meter you should mesure a voltage variation at the NJM pin and as you move backwards at some point the variation will stop and you should get a stable voltage, this point is probably the cause of the problem, then you must test the part in between the 2 points to see if it's fried, my guess is it's a bad transistor or you managed to fry the NJM input.

That's what I thought too.
Except: how do I know what voltages I should look for?
