BeatleFred, thanks much for the response! Yes, my unit came with the pin plugs, which were in phono 1 stage when I tried out phono 2 stage. When I tried #1 I never put the plugs back in #2. I will try it out today although I'm sure thats the cause.
This unit cleaned up really nice and looks almost brand new. It had , although consistent usage, was never abused by a Dr. who inherited it from his father who bought it new. I think I scored a nice example for $75.
One last question-I know Sansui is out of business and serviceability of this vintage gear is always a crap-shoot. This leads me to the following- a buddy of mine has an AU-11000 professional series integrated which he bought new overseas in the mid-70's. He hasnt used it a while as he says wierd things are happening, no specifics (yet), but when he depresses certain switches or turns the volume knob channels cut out or something like that. We are going to give it a good cleaning and see what exactly is going on. Its a sentimental piece to him (brings him back to his Navy days going to see Asian Wish Bone Ash cover bands), but he's on the fence about putting a lot of money into it. Any recomendations or service techs available locally to Connecticut (East Coast) for a reasonable resurrection?
