My amp won't turn on, and I don't really know why. It is a U.S. Masters TVA30 Class A Tube amp. It's my first tube amp so I don't know a whole lot. I got it over this summer, is it possible that a tube is blown already? Would that cause this?

Check the fuse in the back of the amp, that's usually the first thing to look at.
#3
Have you checked the fuse in the plug+back of amp?
take it to a proper tech - they'll sort it out.

If there's something wrong, 10-15 seconds.
If nothing is wrong, either several years (usually) for the fuse to fatigue, or never.

It's entirely possible that either the fuse, or a power tube, or the power transformer, or the rectifier, could have died. Just because it's new doesn't mean nothing can be wrong with it.

Alright, thanks. I suppose I'll just have to wait until I can come home from school to take it to a shop.

Good luck. Hopefully it's just a bad fuse, that's what it sounds like.
I am assuming by "won't power up" you mean that the lights don't come on and the tubes don't get warm?

Right, nothing happens at all.

^Sounds like a fuse to me.
