It didn't. The pot/switch also had problems. I removed it from the
circuit board, squirted in some tuner cleaner, and worked the shaft.
Now the pot works good mechanically and electrically but the switch is
still unreliable.

I hate to give up when I'm so close. Is there any hope of repairing
the switch if I open up the pot? What about finding a replacement
that will fit into the board?

The only markings on the pot are T S on the bottom of the casing.
The circut board it came from is labeled Golo. Does anyone recognize
what either of these are?



If you open the switch you might be able to repair it. Worst case you
can replace the pot with an ordinary one of the same resistance and then
put an inline switch on the cord.
