My SX-1080 receiver has developed a very loud hum and a lot of distortion when playing records. It was professionally serviced a couple of years ago and a bunch of capacitors were replaced. It has worked fine until now. This only happens with Phono mode--it sounds fine in AM, FM, Aux, & with both Tape Monitors. The hum is the same with either Phono 1 or Phono 2 selected and regardless of whether a turntable is connected. This leads me to suspect a problem in the preamp. Does it need to go back to the shop? Any ideas would be appreciated.
