Thanks for the explanation Arran.
It has all the correct tubes including a 41 output tube. I have a power resistor of 50W at 50ohm in line with the hot side of the plug after the fuse. It drops the incoming voltage to around 108 but the power trans still gets a bit warm around 125 degrees with it just sitting on the bench not in its cabinet. The resistor gets very warm/hot at around 160 degrees I have it heat sinking to the chassis with some thermal paste which keeps it a little cooler.
I am starting to wonder if there isn't something pulling more current then it should although I do have a 1amp fuse in line and it doesn't blow open even on start up.
