Hello all - I've lurked here quite a bit over the past few months, and took the plunge to join. I'm hopeful this awesome community might be able to point me in the right direction in "curing that which ails" my recently purchased vintage Sansui G8000 receiver. The unit had been recently (last October) QC'd thru a vintage hi fi business before I purchased. Most everything is perfect - lights, meters, inputs, outputs, etc. HOWEVER, the Tape Monitor rotary switch has a hiccup. It's causing static and intermittent signal to be delivered to the right side output of the unit (I'm getting the problem in my right side speakers, whether using Speaker A outputs or Speaker B outputs). Gently tapping on the knob can either cause the problem to start, or make it go away. Also, twisting the knob clockwise does the same thing (start the problem or stop it). Can this be as simple as dirt, dust, cold solder joint, etc? Or does this point to a rotary switch that has seen it's best days and needs full replacement? (If full replacement, does anyone have an idea of approximate cost for that type of work)? If the latter, can anyone recommend a repair service in the Greater Washington DC area? I know that's a long shot, but I can't possibly just let any repair guy touch this unit. I'd love to find someone with experience and references. Thanks in advance for any time and attention that this community can share with me. Thanks even more for putting in so much time to make AudioKarma such a cool site!
