Are there any tube amps that don't give off any---

HEAT!! 
I have a very small dedicated listening room, and so I was wondering IF there are any tube amps..I guess hybrid or all tube ( although more all tube)- that simply give off NO heat or very very little heat after full warm up. Since the climate seems to be getting hotter, it would be nice to have the benefits of a tube amp with no heat whatsoever. ( is this even possible?). 
Running AC isn't my preferred way of listening in a small room, so this question is now on my mind. I do not want to consider Class D solid state amps...as I know they are an option from a heat perspective...but just tubes.

I have the same heat issue in a small listening room which is next to my walk in closet. I decided to cut out some drywall near the ceiling and put vents on it so that I can dump heat into the walk in closet. I have Pass Labs X250.8 amp with BAT Rex2 preamp, which together consume 900 W idle.

Hi daveyf...

You didn't address power requirements and such.  I am extremely happy with my newly purchased Music Reference RM-10 MK II used in my tiny dedicated studio.  It sports 4 small EL84 power tubes that produce a healthy 35W per channel.  If curious, you can see recent posts for details.  Best, Pin

I have heard a Shiit Saga preamp with a solid state tube. I could not tell any difference in sound as opposed to a regular glass tube. It ran warm, but not hot. For power amps, I am not sure if solid state tubes exist? It sounded really nice.

In my room, even an amp that puts out just a little heat, over time heats up the room considerably. I already own a couple of amps that put out just a little heat ( one a ss amp, one a tube amp). I also have AC, and in the summer, this is required. The AC runs fairly quietly, but one can still hear it..again due to the size of the room.
My OP was really more about an amp that runs totally cool, vs. one that runs a little warm. ( many tube amps run a little warm --and a few monsters act like space heaters!).

@daveyf If you don't want to give up your Jadis amps you can use them with 6ca7/El34 tubes which will give off considerably less heat than the KT150's you're currently running.


If however you want a totally cool running amp Class A/B SS would be the route to go are you considering a seasonal amp rotation with the Jadis?
