Looks like I melted the socket and caused a short between pins 3 and 4. Going to replace the socket and see if it does the trick

After a bout of covid, I finally got a chance to test this. I have a reading of 0 V at both IC2 pin 3 and on the wiper of the WAVE pot. Depending on where I have the pot turned to, I get positive voltage readings on pins 1 and 3 of the WAVE pot ranging from 0-7 V. Does this mean the wiper or...

Recently finished up a moonshot build and I am not seeing any sort of oscillation in the circuit. The LED in the octocoupler is on, but it's staying at a constant intensity. The only thing I did out of the ordinary was using a 1/8w resistor for the 1M resistor (R1). Otherwise it felt like a...

Pretty quickly into investigating, I found a short across the power terminals on the pcb. Good lesson in clipping leads (and tinning them properly) I guess. Power supply seems to be fine. Does it make sense for the pedal to sound best with the bias trim pot fully ccw? I’m using the ear...

Thanks a ton! It was only connected for a short time (guessing around 30 sec). Do diodes have any visible proof of failure to look for? Thinking I may have some issues with DC jack also -- potentially a short or something. The power supply showed similar behavior (indicator light flashing on...

Hey everyone, first time post here. I recently built the Clandestine preamp and it had worked when I tested the board using a screw terminal DC jack for testing (everything else was mounted in the 125b). When I added the DC jack to the box, I accidentally wired it backward. It didn’t work when...
