A friend of mine had a Krell KSA-250 class A amp. It ran about as hot as any class A amp I have seen. After about 10 years it needed major repair from so many internal parts having severe heat damage. Althogh a lot of people would think that's a pretty long life for a class A amp.l
Stupid class A question
I have a Sugden a21 integrated amp in my second system (my first class A) and I love the sound but I don't play it much in the summer due to the heat. Since it can be used as a preamp, if I get an amplifier, will the Sugden still produce as much heat if it's being used as a preamp? Thanks in advance.
