Yamaha CR 2020 - One Channel Faulty on this Beast

Yamaha CR-2020 Repair — Fixing a Quiet Channel on This Beast of a Receiver Today I'm working on a Yamaha CR-2020 — a serious beast of a vintage receiver, and the younger sibling to Yamaha's flagship CR-3020. This one's been sitting in my shop for quite a while, and I finally carved out the time to dig in and get it running right again. The Problem One channel on this unit is quiet — it only comes to life once you push the volume up higher than it should need to be. Classic symptom, but let's find out exactly what's causing it.
