The famous Hallifactors SX-62A...

Newbie post, please forgive format. Lot's of great info here, wanted to ask a question since it's relative to this post.

My SX-62a gets REALLY hot on the right front, like it could burn my hand if left on the top of the radio. A bit worried about leaving it on? I've retubed the radio and it sounds great, I even found a matching speaker. I know they're supposed to get warm, but enough to cook on?

Thanks,

Lee
