Carver PM 1.5 Low Input/Output Left Channel

My Carver PM1.5 has given me years of faithful service. It hasn't been used since it was lent to friends for a year or so.

The LED's for the left channel show about 1/4 of the levels of the right channel (I did swap left and right inputs, same effect).

If I'm understanding the manual correctly, this would be more towards the input side of the amp than the output. Is this correct? I originally thought the LED's were showing the output levels.

I am an Electronic Tech, but I was hoping someone with experience with these amps could head me into the right area, so I can shorten my troubleshooting time. I did download a schematic, but the designators are very hard to read (some are impossible).

Is the sound equal on both sides? If so, I'd suspect the meter circuit.
It should sound like it isn't there!
