I don't care if it is introducing noise into my Hifi, I've got to have the fan on today

I'm using my Quad 510 monoblocks at the moment, in place of my usual 25W Class A monoblocks. The latter each have a dissipation of 400W! It's far too hot for that.

I'm Dennis.
Barry 400W dissipation for an O/P of 25W is very inefficient.
The maximum theoretical efficiency of class A from memory was about 45%, but that is about 6%.

They are a pure class A design, where the power output doubles for each halving of the load impedance.

The Mark Levinson ML-2 mono blocks were 25 watts Class A and they were huge! So was the Krell KSA 50. All real Class A amps are big, hot and heavy LOL
