Ive been having issues with intermittent volume fluctuations on my rm50 only on the 1st (left) channel ive replaced all the tubes in the amp and blasted everything out with canned air, Im at a loss for what to do next. The only randall repair shop is about 3 hours away from me and i really dont wanna take it all that way if its something i can clear up myself. I read on another rm50 problem post that contact cleaner works but is it a liquid and can i spray it into the slot where the modules plug in?
