Sony Vintage Integrated Amplifier; 1080 Solid State Amp AS-IS

This unit is working but the sound from the right channel is faint. It's about half the volume as the left side. We have not attempted to diagnose or repair. Offering AS-IS for parts / repair only. Also note that the cap is missing from the power switch and the volume knob is missing. These both still work fine. See photos for details.
