It's like autoincorrect or something...
I started a debate on another site about my deluxe amp, last night I replaced the tone
control/switch with a newer CTS 1 meg (closer to spec) and switch, and once done the
hum level dropped and is much quieter. The debate is pot's don't cause hum if bad, I
think because of the current going though the pot if it's shielding or whatever degrades
because of age does something.
Or....perhaps a cold solder joint? I once switched out the positions of a special pot from a Vib channel to the Normal channel due to a scratch that cleaner/lube would not correct. When I got the pots in the circuit, there was no scratchiness in that ‘offending’ pot. There was a cold solder joint causing the scratching noise.
I'm going over it bit by bit checking everything to make sure.
