Hello: I have a Kenwood TS-940SAT with microphone. It sat idle for the last ten years so I tried to rejuvenate it with a Variac which seemed OK. Then when I plugged it in directly and turned it on I heard the big pop, which I assume is one or more of the filter caps. If you're up to repairing and  refurbishing it and either keeping it or reselling it, I have the manual and the original shipping box with all the foam inserts.  Mechanically it's in pristine shape, no dents, dings or scratches. Local pickup in NC anywhere from Raleigh to Winston Salem. Thank you,
