Acetylene No Sound

[ALK2MT]

For the Acetylene build, I’m not getting sound but I am getting LEDs off and on with foot switches. I’ve been troubleshooting and think it’s probably a ground issue.

However,

Is this the correct direction for the ICs?

Any help it appreciated.

Yep, that looks correct.

 

[ALK2MT]

Ok. I’ll start tracing from input jacks.

There was a cold joint on one of the capacitors. Sneaky!

 

[cdwillis]

Was that the culprit? It's working now?

 

[ALK2MT]

No. Tracing the circuit.

Ok so I traced the circuit, repaired the cold joint on one of the capacitors and was able to get a sound in true bypass when off. When on, I’m getting just a massive hiss/squeal and when I touch the case it changes hiss. Is it possible to have a ground issue with a pot or something?

There are a lot of potential problems. Can you show us decent pictures of both sides, and offboard wiring. Also, what are the IC voltages?

 

[Prudhomb]

I had the same problem. I soldered the diode in backwards on the power side.

The LEDs break off on a separate trace before the

I will check that. Thus far, dead.
