Hi so i need help beacause i've had my bugera 1990 with my peavey valveking for about a month and the last time i played with it i turned it off like usual when i was done playing and now when i want to play again it simply wont start, i've checked all the wires and all of them work with other amps so if u think u can help, please do!
If you're getting nothing when you hit the switch, check the fuse. Replace it and see if that fixes it. If it isn't the fuse, check the connections to the switch. Beyond that, you'll probably have to have a good technician look at it.
