Nigel: I was referring to the guitarists habit of driving every amplifier into distortion mode. If they do this with a class A transistor amp, I'm sure they wouldn't like the sound.
You don't drive transistors amps, of any type, in to distortion
I didn't ask my friend about songs made with a class A transistor guitar amp, as you said, there are none. He will reply with a list of songs made with class A valve amps. However, if cracken says he does not wish to examine some class A guitar sounds, I will stop this apparently intrusive and unwelcome contribution.
I just don't see the point in it?, it's a valve amp - the fact it's class A makes no difference, it's got no relevence at all.
But if you want to find class A valve amps, look for 3W or 5W examples - there are numerous ones using an EL84 in single ended output - any push-pull ones will be much higher outputs.
