Oxymoron: High powered tube amps that stay cool

Only the Berning 2100 and 2101 meet your definition.

You may want to check into some of the newer "Green" SS "Class A" amps coming out of China. Their circuit designs are actually extremely effective in terms of efficiency, yet still provide true "Non-Switching" Class A performance.

I still haven't found a Class A amplifier that runs as hot as tubes. I've been experimenting and auditioning Chinese gear as of late. I'm extremely impressed.

If they continue to produce the quality they are presently producing, many manufacturers are going to end up behind the eight ball because the Chinese gear is beautiful, well built, dependable and sounds absolutely wonderful.

Hi Ryno, living in Austin I do empathize with your plight! But I fear that the only time pure tube amps are cool is when they are turned off. . . but then so do a lot of SS class A and A/B like my own JRDG 7Ms. If you were not interested in exploring alternative Texas-friendly technologies, like high end switching and some excellent cool running SS like the Theta Citadel monos, you may want to explore some of the excellent hybrids from Lam and ARC.

Hi Buscis2, could you point us to some Chinese green designs that you have found particularly interesting. . . I will look them up at RMAF for sure. Guido

Just burn fossil fuels to make enough energy to fire up your favorite tube amps and turn on the ac pumped through baffled chambers from an outlying building to keep in comfy.
