early V4 hum problem
#10
SOLVED !! The hum balance pot was shot!! AEB-1 you were right on the money. I actually had to remove the pot from the circuit to see that one side was not going to ground. I fixed the pot by putting a small dab of solder to connect the burnt wires together inside where the wiper swipes. Works a treat !! Now i get to enjoy that sweet feeling of victory after many weeks of trial and error ! Thanks to AEB-1 and everyone that quickly provided valuable information.

I think i'm gonna order a spare hum balance pot. Does anybody know where to get them other than fliptops. Their shipping fees to canada are pretty expensive.

Bad pot

fixed pot
