Oh, it was the power transformer, alright. You should have seen the smoke coming off that sucker...And it is HOT HOT HOT. The wax inside the transformer melted and was coming out.

I think when the Brand Z 6X5 shorted out, the damage was done. Then I come along, buy the set and try to get it going again...My guess is that the 6X5 short caused windings in the power tranny to partially short, and it couldn't handle the stress of normal usage after I put in the good 6X5 tube.
