4 position tone control 90X
#2

Fran

I have rebuilt several Philco radios that use this or very similar type of Tone control, including 90 and 70 models.
This is the first time I hear about this defect having occurred. The effort of the sliding contact moving across the contacts' caps is very light.

Well, in the worst case for a while you will have to operate the radio without the tone control, it will just work at the peak of the treble transfer; when you locate the new control or fix this, you could install it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
