I have a beta lead with a broken treble pot (the knob broke off). I checked the schematic and it's a a 100k linear pot. Having a hard time finding a replacement, anyone know of a supplier? It's a 4 leg pot, 4th leg is just for support on the board. I have read that these have been replaced with a 3 terminal pot wired to the board when an exact replacement couldn't be found but would prefer to replace with original style.
(edited, found correct info, it's a 100k linear pot)
