keeping amps cool?


How about having small air filters blowing on the amps fins to keep amp cool. Apparently keeping devices temperature power extends life?

Yes, keeping cool extends life, electronics and humans. Try some of the laptop computer coolers, very inexpensive, quite and effective.

I would only aim a fan at the cooling fins, unless I was certain the amp did not have a built in self bias scheme.
The Parasound HCA-3500, for instance, heats up appreciably until it reaches a set temperature.
We took the top cover off my friend's HCA-3500, to see if it would run cooler. It biased up even higher, with the cover off..
