Hi,

I'm new here and don't have a schematic or much help but it would sound like you maybe have an improper connection somewhere and if it only happend after "recapping" , is it possible you mistakenly relocated a wire on connection?
I guess I would measure the filiment voltage across the normal tube and compare with the other one. Seems like the filiment voltage is too high and may burn out your tube very soon if left this way. Trace the wiring to the filiment pins and check to see that it only has wires to it the same way as the good tube.

Also you may even have a short between pins or wire crossed somewhere causing this condition on the tube socket.

Hopefully someone else more familiar can help you a lot more... just throwing in my "2 cents" ha... best regards.
