Hey John, what kind of fun are you getting? DC or AC? Or powered through USB port of some other device? My Rotel RB-1080 power amp gets really hot (though never has shut down) and I want to buy one myself.

I posted something similar on Club Rotel shown on This Link It has a lot of info, and I was really impressed with DIY work of PewterTA in that forum. You may wanna check that for ideas, however, I am not able to do any of those myself for now. I am looking for something simplier.
