Ditching Class A Amps due to Heat - Sort of a Poll


A discussion elsewhere about the future of Class A made me wonder how true one statement really is. So the questions are...

Have you done away with your Class A Amp due to Heat concerns?

Will you be moving away from Class A Amp due to Heat concerns?

Will you never buy a Class A Amp due to Heat concerns?

I only have a class A/B unit that does Class A up to 6 watts with almost no heat so really can't speak for those who have used in the past or currently own and run Class A Amps.

after a good 45 min of jamming some motorhead, onslaught, sodom, Y&T, vicious rumors, the ol monos' get pretty darn hot. its nice in the winter, not bad in summer, they are A/B not A, but they sound oh so sweet!

weight not an issue.

wasted heat , don't care,

wasted 3 volts of electricity,..hahahahah don't care

burn baby burn. the heat is what helps with the sound out of the speakers, sounds sooo good! gary and Vinnie Moore, Schenker, Derringer, UFO, Holy Moses, sound soooo damn great!!!

when nice and hot, means everything is wicked, will sound better, to me it does, 

then some Donovan, john denver, spooky tooth, Kim Simmons, teslas first

 

sounds awesome.

 

 

 

 

Great Question! 

I had a pass labs xa25.  Loved the amp but it was = to having 4 60 watt light bulbs on.  Yes there was heat and yes I didn't like it because I was running my AC in the summer while a small heater was on.

The sound was great and likely at some point in the future I will get another one but only for a sound diff.  I switched to SPL S1200 power amp which runs cooler than the SPL Preamp!

Hot amps are more likely to catch fire.   Here is Art Dudleys humorous account of an amp catching fire in his house .

I read that story and my first question would be something about the fuse that was used in the amp that caused such a mess.

If there were even the slightest chance that naming the manufacturer would spare someone else this inconvenience and potential danger, I would do so, but the law of averages suggests that the next time a modern electrolytic capacitor fails in such spectacular fashion, it will be in the power supply of a product from a different company. 

That lame excuse does not hold up to scrutiny, at least not in my country which bears no similarities with America.  The dodgy manufacturer ought to be named and shamed.  Should lives have been lost the dude would be guilty of criminal negligence.

I do hesitate before leaving the house for more than a couple of minutes with the amp on. My amp is not near anything but even if a tube blows, I want to be able to shut down quickly. When the power goes on, I’m home for awhile.
