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.

My Almarro A318B draws 250w and it put out enough heat to warm a house:)
It seems a lot hotter than two 125w light bulbs.
