I'm cleaning the pots on my marantz to get rid of distortion in the right channel. I dont want to clean them all if only one is usually to blame. Any ideas which pot it might be?
Generally, the volume and balance controls cause worse problems than the tone controls.
However, switches tend to cause more problems than pots.
I would treat ALL switches and controls. Give extra attenton to the volume and balance controls and to the tape monitor and function-selector switches.
