Need some help repairing vintage RCA amplifier

Without having to type up everything I've already done can you please look at this thread elsewhere and let me know what might the problem be. I'll upload the schematic here. Thx

I need assistance tracking down failed component on old RCA amplifier

The right channel is being amplified, the left is not. I tested the transformer voltage on both outputs and trans is working at around 23v per leg. At the output im getting around 4 volts or right, 0 on left. You can still hear unamplified signal through left channel though. Does anyone based...

You already had a post on this.you should keep uses that one.
Schematic helps. I would start by giving the voltage measurement on the two output transistors of the channel that doesn't work.
It's possible that coupling cap that has 4 volts on it is leaky .tall 1000uf

Anything as old as that you will need to replace the capacitors.

Just the electrolytic types.
