I've never really noticed that my 2300c runs hot, let alone even warm. And yeah, I've noticed that if I take mine apart right after running it for a while, those little transformers are practically the only things that get warm in there.

That's the sort of info I was asking for. Adjusting the heatsink helped tremendously, but maybe I still have a problem, as the whole "top left" really is noticeably warm. I have also found since my previous posting that the 2300c is not charging batteries properly. Capacitors?
