Here is the pot in question: https://www.ebay.com/itm/POTENTIOMETER-OHMIC-RV6N-10K-OHM-20-Lot-of-1-pcs/260973677675?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649

You know what, I'm an imbecile. I misread and thought this was 10 pots for $3, haha... There is another listing for a lot containing 20 pcs. for $27. Now that would give me more than enough for a Six Shooter EQ. But for that, Alpha PCB mount pots are the recommended, more practical and indeed cheaper alternative. I will probably go for those. But I do want to one day build like a fuzz with all unnecessarily big parts.

I don't think the juice is worth the squeeze for those pots. They aren't specifically made to fit in X piece that you're repairing or anything like that.

I'm blushing over here, stop.

hahaha

Those pots might actually be surprisingly compact. I have some that look similar, the caveat is that the shaft is 1/8th inch, making knob selection an additional issue..

I'd buy new production from a reputable dealer, and grab random nonsense when money/project is not hinging on its success. There is a LOT of weird shit out there once you veer into surplus/old stock.

Is "low" on the level control connected to ground?

I've observed similar signal pass/ignore pot position when the pot is just a variable resistance instead of a voltage divider.

That may not explain why you're losing all signal at maximum (is that an accurate statement?) but it could be a contributor.

Leg 2 is ground

Leg 2 and 1 measure 50k when the volume is at minimum
This is true for channels 1-3
Channel 4 reads 70k

Channel 4 doesn’t go through the reverb

The ground wire connecting the input jack banks and the pcb was not connected.

Ch 1-3 work normal. Ch4 doesn’t have a gain control, which used to be channel 3. Someone reversed the input wires for 3 and 4

Reverb still doesn’t work. I’ve got this to useable for my needs so I’m putting it back together and maybe tackling he rest later.

Goddammit! When i was putting it all back together, i dropped the grille on the speaker and punchtured it twice.
Glued it back together. Sounds litAF with the torn speaker but will have to replace it eventually.

Prob look for a matched pair. Any recommendations on a 16ohm 80w peAk driver?
