I recently got my Sansui G9000 a couple of days ago. I had posted in Solid State, but figured I should have posted here. The prior owner claimed it had had a cleaning 3 years ago, but after blowing out several huge dust bunnies out of it with a Datacvac electric Duster, I doubt. He mentioned that sometimes the right channel would not come. I have found the culprit to be the Tape Monitor control. If I slightly wiggle it the right channel comes on fine. Now, I obviously had the top off earlier but found the pots, at least the volume and so on to be hidden under a board. Is the Tape Monitor easier to get to? Also what would be good to use to clean the grime off the faceplate as I don't want to damage silkscreening?
