Heat

antinn, thank you. I believe all of my capacitors are Vishay and that’s as much as I know. Anyway, I’m thinking that I’m safe in the attic as long as I stay away from playing time during the hot season. Because of the hardwood floors, it is very dry up there which is also good for my electrostatic speakers and in the fall and winter, it stays very cool.

Dear friends : ""  Heat is the enemy of audio equipment. "" and I can add: operation out of the limits of the source of electrical power.

Now, every decent amplifier designer/manufacturer takes in count those both parameter in his design overall/main targets and his calculations on the design takes in count both parameters.

So if the amplifier is well designed no one needs any " crazy fan " even in the attic due that not only because the well designed unit but because that good engineering designer already designed his unit with a thermal protection and to electrical protection too.

Look, I own two Levinson 20.6 monobloks and in my country ( México. ) people have air conditioners only in those country places where temperature goes as high 50° C but in zones where as my place that does not happens we in reality do'nt use even with temperatures at 35°C.

In the winter and in the cooler days that normally never gone below 0°C the pure Class A 20.6 puts as warmer ( heatsinks and all the amplifier external metal surfaces. ) as in summer. Difference is that during the winter the time to get hot is a little longer.

Yes, those amps does not puts warmer but hot really hot, you can't touch its external heatsinks even the face plate and the handles are warm enough.

Guess what? no matters what the amps never switched to its thermal protection circuit. The 20.6 has not internal fan and its electrolithics filtering caps are rated at 95°C by Sprega that today is member of Vishat group and the Wima caps used in the circuits are rated at 105°C.

The design is all about, period.

Those amps came around 1987-1989 and never failed in any way:

A fan can add  dirt, noise or grunge to the electric line and make the sound bad. Make sure it is not plugged into any sockets or lines that the system is on.

Everything will overheat and blow up attic is worst place for a stereo.

ebm, except in the winter.
