Any suggestion on refurbishing those pots?

Surely any owner of "classic" equipment should have a can of good contact cleaner always at hand!!! :-) Perhaps even WD40 would work??? If the pot is just supplying a DC voltage, I guess you could always hang a big capacitor on the wiper!? Have you tried simply rotating the pot back and forth a few dozen times? This often helps, at least a bit.
