C44 is a 60uF non-polarized electrolytic mounted on the front side of the motor. Look at the under chassis view on page 3 of the schematic:

You might be able to do some rewiring to replace the tone switch with a potentiometer but I would try to get a switch before going through that trouble.

Her's the poop on that cap setup on the tuning motor.
Has 2 mfd 20,250 volt dc caps wired together.
Both positive leads together,and of course 2 negative together.
Positive ends are wired to the lead on the tuning motor that also has one lead of the .01 cap.
Can this be right?
