Here is the story and what a sad one it is. I borrowed my amp(Laney HCM60WATT) to a friend on a weekend and he was playing at a gig the friday and sunday again. I received my amp the next sunday. I played for about a hour switched it off and went to bed. The next morning my amp was smoking and funny noises and our TV was messed up too. The electrician says that the amp was overdriven. It looks like some small component blew on the circuit board. He says it will cost me a fortune too repair it, but when I switch it on it makes a humming noise. I am confused too what can be the problem. Any suggestions too what may have been the problem.
