How do I find why my 2220B won't play off both channels

Your Marantz 2220B may not be playing sound from both channels due to several possible issues:

1. Dirty or Faulty Controls/Connections – Cleaning the pots and connections with Deoxit helped initially, but further inspection may be needed.

2. Mono Mode Works, But Stereo Doesn't – If sound comes from both speakers in mono mode but only one in stereo, there may be a problem with the left channel circuitry.

3. Component Failure – A faulty resistor (such as R317, which was found to be open in a similar case) or capacitor could be causing the issue.

4. Internal Inspection Needed – Checking for visibly damaged components like burnt resistors or capacitors might help identify the problem.

Further troubleshooting with a multimeter and schematic may be required to pinpoint the faulty component.
