Can I fix a fried amp?

Question

I was hooking up a compaciter and didnt realize the compaciter had a charge stored in it. When tring to hook up to my amp, it touched the chassis of my amp and the amp has ceased to work. Checked all four external fuses hoping it just blew one of them, but they are all fine. Is there anyway I can fix it inexpensively because I have no warranty on the amp.
