On my TSE, the transformer will get too hot to leave my hand on it for more than a few seconds. It will usually take a few hours to get that hot though. What are you wall voltages at? I know mine typically run quite high.
Please answer these 3 questions, otherwise it´s a guessing game.
What is your filament load in Amperes?
What is your +V in Volts and its DC load in milliAmperes?
The amp is a Tubelab SSE. The load on the 6.3V winding with a pair of KT88's and a 12AT7 is 3.5 A. The 5AR4 / GZ34 draws 2 amps from the 5 volt winding. The B+ with a 5AR4 is usually around 430 to 440 volts. The total current from the B+ will depend on the bias current, which depends on the cathode resistor chosen at build time. The usual bias current is 60 to 70 mA per tube plus about 18 mA for the 12AT7. It should be under 160 mA total.
The only real unknown is whether this amp is running like all the others, so the two important questions are what value cathode resistors are in the amp and how much voltage is across them. Knowing the exact B+ voltage could determine the exact load on the transformer.
