Just my two (2) cents, but it sounds kinda like a CSJ (cold solder joint). I've had a few tube radios more than one amp that would tune up "correctly" w/it was warm, but let it cool down 20 min.+ & come back to "NUTHEN". I've learned a lot when it comes to high voltages & decades old "Boatanchors". Of course, I haven't wiggled components on a RF deck, PS, etc., capable of 14 Kw!! LOL

What is a 'vacuum tuner'? Did you mean a vacuum variable capacitor? If so, then I very much doubt if that would cause the problem you seem to have. If it's a vacuum variable, then if it starts loosing vacuum it starts to quit, gets to where it can't do any tunning at all. If waiting, then starting over seems to cure the problem, you can bet that the 'vacuum' hasn't been 'renewed' in some way so I'd doubt if that's the problem.
I'm still not sure we're talking about the same thing, so all this is a guess.
