No heating problems with mine, I've had it for a couple years now. It does run class A in the lower output range, so yeah, it'll run pretty warm. I've run mine loud for a couple of hours w/o any issues. I've never pushed it hard for many hours, though.
I did have an issue with my power button. It wasn't working very well intially, the remote worked fine. I got lazy and never brought it back. After a few months, no problems, the intermittant button problem has disappeared.
