Hi. New here and hoping to find some help for a problem thats been driving me crazy. I have a stereo that as I listem to my vinyl records will eventually cut out the sound from one of the speakers. It consists of a Pioneer P-120 turntable and a Sony amp and a Sony 5-disc CD player plus a tape deck which I rarely use and a pair of Sony speakers. What happens is that when I play records, everything sounds great but inevitably one channel will cut out and I will only get sound from one speaker. I assumed it was the turntable's fault so I would unplug the turntable, screw around with the plugs and plug them back in and this would almost always work. OK, bad wiring on the turntable right? Then I discovered that if I left the turntable running and shut down the amp, turned it back on and switched the input to the cd player or tape player and then back to the turntable, the sound would be fine again. I never have this problem unless I am listening to records. I can play CD's all day long with no problems. It's almost like the amp is shutting down one channel to protect itself from an overload or something. This is absolutely driving me crazy. Anyone have any ideas? Thanks in advance.
