Too much gain.

It could also be that you are simply asking too much of a single 2x10.

this is the first thing i'd look into. even though a lot of cabs give you huge numbers for their power handling, the vast majority can't take anywhere near that number in real world usage. the second thing i'd look into is try swapping some tubes around one at a time and see if the problem goes away. then i'd look into getting the mosfets biased.

bias is setting the mosfets (or tubes in the case of tube amps) to provide optimal power to the amp. it can be done by the user with a multimeter, but i don't know how to do it to tell you how, and in the case of the 3 pro, it's critical that it's set accurately because it can burn your amp up if you make it too hot. so i'd say take it to a tech if that's the problem.

I agree, take it to a tech and get him to diagnose and repair your amp. Don't mess with what you don't know and make a $50 repair into a $500 one.
