My Marshall code 50 suddenly stopped working while playing. I heard a little "click" sound an the power went of on the amp. I did not blow the speaker. Spoke to a friend that suggested that the amplifyer fuse was the problem, as it was nothing wrong with the power outlett i used. Is this a problem i can fix myself? is it likely that the amplifyer fuse are the problem? 

sorry about my english, i´m Norwegian ;)
