How hot are they ?

Nobody can help me with this ?

If you ask that question over at Audio Asylum you should get an answer.

Just did thanks .
By the way...I posted this on the 28th and it didn't appear until today ! Go figure .

All things being equal, SET amplifiers run hotter than typical EL34 integrateds, as they need to operate in Class A, whereas most of the former run Class A/B.

That said, you should not find a 300B objectionable. And, depending on how hot your particular amplifier is biased, it might even run cooler. The 211 and 845 normally throw a good bit of heat, though I once owned an 845 integrated, and did not find it bad in terms of heat. It did, however, have the most obnoxiously bright blue LED indicator I have encountered. You could guide ships through a stormy night with that thing. Eventually, I got the idea of covering it with a piece of electrical tape, which allowed me to then listen to the amp in peace.

For a SET or other amplifier operating in Class A the amount of heat generated will closely correspond to the AC power consumption of the amp.

For example the Cary CAD 300SEI is a stereo integrated amplifier employing one 300B per channel, and a total of three 6SN7 small signal tubes. It is specified as consuming 107 watts of AC power. So the heat generated will be similar to the heat generated by a 100 watt incandescent light bulb. 211 and 845 integrated amps, of course, will generate significantly more.

If the manufacturer's literature on a particular amp does not indicate AC power consumption, an email to them would hopefully provide an answer.

Excellent info...thanks Trelja & Al . Especially like the AC consumption thing !

SO hot i cook eggs on mine!!

As Al mentioned above, the Cary CAD300SEI is great SET 300b integrated option, and I do not find it's heat output to really be any more/less then a typical tube based integrated.

Hope springs eternal Almarg ! I have emailed a retailer , for Melody products , as well as the manufacturer for Decware and received nothing in the past 3 days ! Must be a well kept design secret !?
Oh well .

Thanks for all of everybody's help .
