Well sounds like you may have created a few problems by having the set on without the speaker pluged in. It may have damaged both 41 tubes. And it might have damaged the filter caps. Check the HV and see if it is up to what it should be. If it seems ok then try connecting another filter cap across one that's in the set. If the hum decreases then you got a bad filter cap in the set.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got it!
