How warm does the average amp get? I have a Panasonic SAXR25 600W 6.1 Digital Reciever. I finally got my HT all together and after about an hour of running it the reciever gets pretty hot.

Hotter than "warm to the touch" but only slighty cooler than burns on contact. If you leave your hand on it for 5-6 seconds you really feel it. That's the best way I can describe it without actually busting out a thermometer.

The hottest spot is on top right behind where the speaker cables are connected.

Is this normal?
