This is the vertical centering control I touched when the set died.
No tin whiskers visible inside, but I did get erratic readings when I rotate while measuring resistance. Some DeOxit seems to have taken care of it.
It was F103 - a 3/4 amp fuse that popped.
I had to order some Littlefuse N-3/4 type fuses.
Meanwhile, I replaced the original 1V2 and 3A3 tubes with NOS.
We will resume when the fuses arrive.
