Probably a bad solder joint on the filter cap.

My 2-C, which I bought new in 1968, suddenly developed a very loud
buzz which is there, unchanging, no matter what position any controls
are in. Suspecting the main filter cap, I took the bottom cover off
and turned the receiver upside down, turned it on and the buzz was
gone. I could not provoke it to come back. So I reassembled it and it
worked fine for a few days, but now the loud buzz is back. I'd expect
a bad electrolytic to stay bad. Is there a known cause for this
behaviour? I have the manual with schematic.
