How hot is pure Class A solid state vs. SET?


Generally speaking, would a Class A solid state amp generate a lot more or similar heat as a single ended tube amp? Not surface temp, but the air around it. Tubes get hot, but their surface area is usually very small compared to big heat sinks on a SS Class A amp.

I am thinking about going from an AB SS amp to a Pass Aleph 30, but I am concerned about the heat. I have an Almarro A205A 5 WPC EL84/12AX7 SEP amp that is fine for me in this regard.

I run an X-250 into totem forests. according to the meter I never get out of class A, and they wail, I mean loud (Real loud) in a 14x20 room. I can stick my fingers right into the fins after an hour no problem. Warm, yes, very hot, no. Does taht help? That's 40 w class A....
