Can I fix my guitar amp myself?

I have a Marshall Valvestate 20 (8020) practice guitar amp. The built-in reverb has stopped working, producing just noise when you turn it up and a sort of wobbly sound if you bump the amp. Also the amp itself has a lot of hum, which goes away when I touch the strings. I'm too cheap/broke to get it fixed but know how to use a screwdriver and a sodering iron. Suggestions?
