I try to run my 'warm' sets on variacs set to about 105 or 110V. It seems to keep the transformers a lot cooler to the touch. My RCA D-22 used to get very warm but now I can run it all day and still hold my hand on its trans.

I have never thought about the resisters temperatures before seeing this very good discussion thread.
