Hi Dan, do you have the pot out of the amp? Can you post some photos here. I have become something of a pot sleuth lately in my attempts to locate replacement units for things I have been given to repair.

Dan, you could try De-Oxit spray; the milder version used for pots. (I think it's called DeOxit Gold, but don't rely on my memory!).

I have the same receiver and my volume pot does the same thing... i know how to solder pretty well, but i don't know if i want to take the time or effort to do this if someone does find a replacement, though it would be nice to know the part. Is there any special technique for using a cleaning spray like that... or precautions?

hi--it looks like the cleaner has worked. the set operates like new. ill see if it lasts awhile and report back. i actually used cleaner and then a cleaner lubricant. both sprays from radio shack. cost $23.00. like dillrepair i did not want to use a toxic spray so i put up with it for 15yrs. good luck and crank up the volume--dan
