SummerTime and Amp Heat

Heat is the enemy of electronics. "Sounds" like you are on the right track.

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.
