Hello...I just bought a Rotel RA 980bx amplifier .I always wanted to have this amp but...I tested it before i buy it with a cd player and it was fine.At home when i pluged my turntable a buzzing noise came out the left channel and no music.I unpuged everything from the amp and left only the left speaker on that had the problem and the noise was still there.changing the input selector to cd or tuner there is no noise...i cleaned the selector tha problem remains.when i switch the amp on for 2 seconds the noise isn t there....it apears 2 seconds after the protection light turns of and it increases from zero and it gets loud and gets stable....is this a capacitor problem at the left chanel of the internal phono stage??any ideas....???sorry for my poor English...

Sounds like this may be an earth issue. Check that the turntable is correctly connected. Have you tried running the amp, with phono selected and turntable disconnected? Doing so would help establish the problem.
