Back in the 70's I worked at a TV shop. We would repair Amps for a local music store. One time they brought in two amplifiers that would set off the protection circuts and wouldn't work. I ended up replacing the power transformers. That fixed them. That would be my first guess as what your amp needs. If you have a music store you can take the amp to, they probably have a service for repair. You may find someone on the Net you can ship it to if not. The amps I repaired sound like your amp.
