Ive had my pro junior for many years, and recently gigged outdoors with it. it got some moisture inside cuz it was cold out that nite. well next gig, i blew two ppower tubes, and fried 2 maybe 3 resistors on the board as well as the fuse. well my friend wrapped the fuse in foil, i replaced the tubes, it now powers ON, but still no play, im sure due to the fried resistors. how do you go about fixing this issue, is this brain surgery or can i be shown how to without screwin my amp up?

I think you have been very lucky if "wrapping the fuse with foil" you haven't damaged further components in your amp. Fuses were invented to avoid current overload, and it is not clear how, despite being burned, they have not protected all other components.
If a resistor appear "burned" very probably it is interrupted. The resistors need to be replaced, but..
...reading your words I can understand your knowledge in electrical circuits is at a very beginner stage. Do you know that tube circuits involves very High Tension? Do you know that can be an hazard touch some particular point inside your amp, even if you have just disconnect the mains?
I think the remote instruction can be very tricky without a knowledge base. And a friend that wraps the fuse with foil may not be your best friend (or of your amp).
May be that for this issue you go to a service center, and in the meanwhile you can start reading about electronic circuits and build up your know-how. Ready for the next time.
Excuse for my english,
ciao
