It was working fine, then I get this 60 cycle like loud hum which the volume knob barely effects.
I checked the 4 diodes with diode test function and they are good. The AC transformer runs next to these 4 diodes.
There is a 1000uf electrolytic capacitor right above them. It looks like an AC filter cap?
Does it seem to you it is a bad cap?
I have a lot of 2200uf can I use those?
