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

It's too hot for pretty much anything let alone a red hot amp, good you have a fall back amp:)
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%.

It all depends on what type of class A and what load it is specified into.

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

You cant beat a bit of fan :eyebrows:

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
With a bit of creative thinking No need for a fan
