When I was in college, we had a Hunter Bandit 2000 at the club station.
At some point it lost a lot of power output. In troubleshooting it, we
discovered obvious cold solder joints where the wires of the filament
choke went into the solder lugs that terminated the assembly. After
re-soldering them, the amp put out more power than it did when it was
brand new!
Check every connection in the filament circuit.
