Ralph, I have cleaned the contacts with mineral spirits and put a light
coating of NO-OX-ID on them pushed the boards on and off a few times to
transfer some on the NO-OX- ID to them - No joy.

I have a can of Deoxit. I can try it.

Thank you for the suggestion.

By the way - I have been finding filter pots on used Flesher TU-300s glued
down. It will not chip off with a greenie or even a razor blade. No good!
Active filters drift and must be re-tuned every year or two. I found that
mineral spirits applied with a Q-tip will soften the red glue just enough
to break it loose without damaging the pot. And the filters did need
re-tuned!
