How is your amp coping, left on in this hot weather ?

If I ran all these in this weather, think I might end up as crispy bacon

Actually, pic was in the late 70's, all but one pair of the Quad II's I sold.

You should be called Quadman.

How hot your SS amp runs depends on the bias. My (modified) 405-1 runs cooler than my 405-2s.

True, about the bias, an unusual situation with the Quad 303, also depends upon how much voltage is dropped by the series transistor in the regulated power supply. My oldest 303, a very early one, drops less than later ones that I have, hence heatsink runs cooler, even though bias is adjusted the same on all four 303's that I have.

I bought my 405 new about 1976, converted to -2 using the Quad 405-2 kit about 1987, did notice that it ran much warmer when ticking over.

My amp is an Usher R1.5 and it gets bloody hot.

Try a Krell KSA100 if you want hot. 650 watts being blown up and out by two fans. In the winter it's lovely, you can stand over it to get a warm whilst making your next music selection.

When it's 30c outside, it's not so pleasant. Especially if, like me, you like to keep the windows shut whilst listening to improve the noise floor.

In hot weather, I used a class D amp, runs as cool as a cucumber at normal levels.

A blow job with seasonal fluctuations then.

Interesting.

Due to my power amp being on the lower shelf of a big heavy coffee table with maybe six inches of upper clearance I thought it better to rig up the fan. I have arranged it so that the fan blows air down into the casing rather than draw it up and out. On a hot day I have to have the windows open otherwise the room is way too warm but I'm looking forward to heating the room in winter.
