Thanks for the quick responses.
I have ordered a new output tube which should arrive early next week. Hopefully, the new tube will solve the problem as it is the easy fix.

Vintagecollect - If the new tube doesn't eliminate the hum, did the above quote mean I should change out the half wave (1N4004) with a full wave rectifier? The ones I have seen have 4 leads instead of two. I am not exactly sure how to hook it up.
BTW, I bypassed the 1N4004 with a .01mF 500V ceramic cap. Didn't seem to make much of a difference though.
