Frozen Potentiometer

by cg591 » Thu Jan 17, 2013 1:05 am

My AMI B has a stuck "Gain" control. Won't turn at all. This is a 4-terminal type, which I have been told is no longer made. Does anyone know of a method to free it up without destroying it? Thanks!

I would spray some volume control cleaner into it.

I use Nu-Trol:
