Believe it or not, plain rubbing alcohol and a lot of time will
un-freeze the shaft from the bushing when even WD-40 won't do the
trick. Thanks to tube hi-fi legend Earl Yarrow for this tip.
Quoting Steve Mulder <[email protected]>:
I'm looking for suggestions on how to deal with a frozen
potentiometer. It's on the back of the vertical gain switch on an
Eico 435 scope. I tried contact cleaner and a bit of torque, but it
won't budge. What else could I try?
