Onkyo receiver in need for a good clean up!
While internally it wasn’t the cleanest (ok, it was filthy) and the metal case of the radio tuner had rust spots on it probably from storage in a garage the PCBs looked OK and the transformer primary measured fine so it was powered up.
Surprisingly it worked so everything was given a good clean up including the tuner module. The electronics inside the tuner module looked nice and clean with no sign of water ingress.
This unit has a proper transistor power output stage rather than then an impossible to repair module that went obsolete years ago.
