So I have to wonder why this is happening with a new tube either the tube is defective or something else is being affected in the audio circuit. And with the old tube in all the voltages came back to normal so this was the problem area. So what possibly could cause this when the tube conducts.

That's almost always caused by excessive grid leakage, IE g1 being pulled WAY too high ( off 0v) forcing the tube full on, C55/C56 bad / leaky? If there were at one point, the output T5 may be damaged, and needs to be tested, but it says 0v at pin 2 of the 6gk6, if you do not see this when it's up and running, C55/C56 are leaking the 90v from the det.
and do check the output x-fomer.
