OK. Just got my amp back from repair and now I have to turn the gain control to max on two of the four channels I have for the front components. So basically at low volume levels the components are bearly audible and are distorted. What gives. Did I just waste money on a repair or what. BTW the amp went into the shop for a failing Power Supply. The amp seems better except I can't here anything at low volumes without getting distortion from 2 channels. Also I checked to see if maybe I had bad channels and it's not that either. HELPPPPPPPP!!!!!
