Pioneer SA-9100 worth restoring?

Today I picked up one of these amps for $5 from the tip shop. Cosmetically it's in reasonable condition, and I really like the styling and all the inputs. It has 2 phono, 2 tape, 2 aux, tuner and Mic. The build quality seems really good, has anybody owned one? The cord has been cut so I assume it's not working. I'm happy to spend the time and money to bring it back to spec, but only if it's going to sound as good as it looks.
