I was able to find zero information on what a Scott 850D is. When's the last time the capacitors in the power supply were replaced?

If the electrolytic capacitors are dried out, the surge after a period of dormancy could have taken one (or more) out.

That's because I wrote "850" instead of the correct "350 D" as I should have. Sorry about that. It was completely refurbished one year ago by Mapleshade (which means a gentleman who is a Scott expert whose name I forgot).

It was sounding great as I left, and now still sounds great, plus a low level hum that occurs with none of my other sources. I suppose that even though it was refurbished, it could still have a bum tube.

  No need to be sorry, typos happen.
  
  Timbo and mhardy6647 have given you some good advice above, as to where to start. Good luck with it.
