Hello Al,
Do you have the old original and if so what's wrong with it? Is it part of the volume potentiometer or is it pushbutton etc.?
Johnny
It is the off/on and tone control switch. It is not a push button, it is one that you turn. The Bakolite material is burnt by one of the contacts. From what I can tell the contacts are bad. I could probably take it apart to get to the contacts, but I wouldn't be able to rivet the part back on.

The tone control is a 100K pot, with an ON-OFF switch. You can use any garden-variety 100K switched pot (preferably linear). RadioDaze sells them. The switch is a separate unit, piggy-backed on the pot.
If the shaft is too long, cut it off. If the shaft diameter is too small, improvize. If you need a flatted shaft, file it off.
