I think noromance is on the right track. Tubes are inherently hot.
OP, its normal for tubes to be way too hot to touch. Perfectly normal. Most tubes are hot enough to warm up the top of the amp, at least the area right around them. Anything beyond that, its normal for the transformers and all the rest of the amp to warm up. But these areas should only be warm, never hot, no matter how hard or how long you run it.
