I bought my Pro-Mod used and have loved it since day one. I mostly use it at home and the occasional band practice, so I've never had to use it at full power. The problem is, when I do switch the amp to the full power settings, and turn the amp back on, there is a very noticeable "rumbling" hum coming from the amp. If I gently hit the amp with the palm of my hand, it goes away for a few seconds, but then returns. I'm assuming it most be due to a bad power section tube. The amp sounds great at half power.. Just wondering if you think I'm on the right track.

That definitely sounds like a tube problem. Maybe a loose socket or just a bad power tube. I think it would happen all the time if it wasn't a tube problem. 95% of most tube amp problems have to do with bad tubes.
