Berning ZH270 runs relatively cool for a push pull tube amp. It uses a screen or "grid" drive which allows it to run much much cooler than conventional tube amps. Overall, its very easy to live with and is about as reliable as you can get in this hobby. The tubes last for a very long time too, another advantage to this design. Best if luck.
Oxymoron: High powered tube amps that stay cool
or even reasonably cool. is there such a thing?
(i find it vexing that living in a hot climate area, houston, that the high powered SS amps i like all run class A / room heater).
