I have a Pioneer KP-500 Supertuner and only one channel has output to the speakers. I'd like to get it working again. I have the service manual but I was wondering if someone on here could identify what to check or replace first.
Thanks.

Could be anything from IC4 on out to the speaker. IC4 decodes the FM and generates the low-level audio that gets amplified after. You would need to start at the power stage closest to the speaker out and inject an audio signal and verify it getting through and work back through each audio stage.
