Probably the elecrolytics need to be replaced as a bare minimum. I would not power it up again until this is done. If the paper capacitors haven't been replaced, I would do 'em all, and probably all the carbon resistors as well, as it will only be pennies apiece and should be done all at once. Also I would apply a tiny amount of WD40 to each switch and control bushing, and give all contacts and control innards a nice spray with Deoxit 5, and let dry overnight. I'd probably clean out tube sockets and pins with a little Deoxit on a pipe cleaner, and check for firm contact with tube pins. Could also be dust or whatever on Tuning Capacitor, and a blast to Deoxit usually does it, but if there is a lot, a piece of paper can usually dislodge it. Be patient, this takes a few moments.

Let us know.
