SummerTime and Amp Heat

So there you have it, either cool it or don't, another definitive answer from Audiogon Forum. Out of respect for Elizabeth's generally insightful logic, empirical and apparently Florida tested, I realize how colloquial I might have been and so, have to ask why, "It seems each summer I need to do this."? Have you experienced a thermal shutdown?

I live in the Sonoran desert of Arizona. True, the house is air conditioned, but I have it set to 79 degress. Never has there been a problem.

Well the topic IS about heat AND not leaving things on 24/7 - BUT i did have CD player serviced not too long ago for a new laser, and the repair guy commented that the power supply was showing signs of getting old and some of the caps were starting to deform from overuse. He advise that I unplug when not in use. I guess a sharp repair person can tell these things.

I own ARC tube gear. Obviously, the component that runs the hottest is the power amp. The other gear, source and line stage, while also tube driven doesn't run anywhere as hot. I hear what Elizabeth is saying, but my sense of the matter is that heat "ain't" gonna help the gear last longer and can only hurt, especially the power amp. That sucker throws off a ton of BTUs.

There's a couple of ARC authorized techs out there. I'd be interested in their views since they fix the stuff.

I think it's a matter of degree.
