Congrats! You have a well-regarded, classic receiver there. Here’s what I’d do:
- assuming you have no idea how old the tubes are, invest in some new ones. Your outputs are 7591’s, while your inputs are 12xax7’s. For the former:

The latter can be found at many sites.

Mullards and Tung-Sols are good, everyman tubes for this receiver.
- with a microfiber cloth and alcohol or contact cleaner, clean all the contacts -- the inside of the RCA’s; the speaker terminals, and tube sockets. For the latter, apply contact cleaner to the tube prongs and insert them in and out of the sockets several times.
- the gold knob can be reglued on to its axis with standard cement or epoxy. Not too much.
- try GooGone for the sticker.
The capacitors may need replacing after all this time. There are many electronic bench shops in the DC area. Astro Services and Burke Electronics are good ones. They’ll run a bench test and give you a complete diagnosis. They should apply the cost of the bench test to whatever repairs are needed.
