I ran class A amp for a number of years, great in winter, terrible in summer. In summer central air kicked in increasing ambient noise floor to a distracting level, 845SET I presently own has same issues. More recently thought I'd give much lower power class A another try, same issues, went to 300B SET, glorious SET sound quality without the heat.
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.
