Assuming you have replaced ALL the paper caps..... I vote a bad tube. The cold/bad solder joint would be my 2nd choice, but resweating the joints would be the 1st thing I would do as the cost is $0.

It is not within bounds that you have a broken wire in the set, when it heats up it expands enough to make contact....thats a 1 in 1000 shot but it can happen.
