Hi there, one cion modules I built recently isn't functioning correctly and I'm banging my head against the wall a bit.
When it turns on the EOC light comes on, if I trigger it the light goes off. The attack seems to work as it should and I can change the log/exp knob works. I just don't get any decay. It raises to about 9.5 volts and holds there.
Where about on the pcb should I be looking for problems?
Hey,
Please reflow Q1, Q2, U1, U2 and U3 and check the neighbouring parts for bad solder joints and also check diode orientations (D1, D2 ,D3 and D4).
Cheers, Stefan
