Seeking hot running amps

Notwithstanding the perceived heat given off by the previously mentioned amps, no amp gives off more heat than its rating, which in the case of tube amps is about 300 watts, 500 watts tops. The smallest electrical space heater gives off more than that. It is silly to buy an amp for its "appartment heating" capacity.

This is not just for warming my room, also listening to music.

Plinius makes great sounding amps that, when run in class A, will heat up the most chilly of rooms.

Which amps run cool? I am looking for an alternative to my freon A/C unit that sounds better than the noise IT makes. What a STUPID post.

We have a customer in Guatemala who has our biggest amps. He has no air conditioning, and does not need it (Minnesota is hotter in the summer than Guatemala...). This despite the amps often being on all day long; the room stays very comfortable. He does this by having vents in the ceiling above the amps. The hot air is then moved out of the house. It works very well indeed (I was there)!

Its probably not a good idea to choose an amp based on heat (or lack of heat) output. But it is a fact that if you choose an amp for its low heat output, it will represent a compromise in the sound of the system overall. So far no-one has been able to change the laws of physics...
