I'm outgrowing my small combo amp and need more power. I have an old Ampeg V6B in my garage that I used to play when I was in a rock band. It's a solid state, 240 watt head. It shuts off after about a minute of use, so it needs repair. I've never seen any of these elsewhere and the SVT seems to be the most popular Ampeg. Is my old V6B worth fixing?
