Hey everyone. I'm new to this message board and need some help.

A few years ago I was given an old amp by one of my friends. It's a Fender "Bassman Ten." Here is some info on it: http://www.bgra.net/2004/review.php?id=62&type=combo

It was a pretty cool amp but eventually I think I overpowered it with a pedal and the thing started smoking. Haha. Unfortunately I don't know anything about gear, so I had no idea that this would happen. It stopped working and has been sitting in my room ever since. I was wondering how difficult it would be for me to fix whatever went wrong with it. I don't know anything about amps, really, so I don't know if I'll have to replace a tube, or if it's something more serious. How can I go about telling what fizzled out in flames? Will it be expensive?

I'd really appreciate any help or words of wisdom.
