Toshiba SA-735 schematic

Have a Toshiba SA-735 that arrived in my shop for repair. Customer doesn't want to spend a lot on repairs, so time budget is limited.
Does anyone have a schematic for this receiver?
Main problem is weak output on left channel. No shorted output transistors. Signal is weak, tracing back to the 4558 op amp. Oddly, both sides of the 4558 seem to carry right channel signals. But where's the left channel op-amp??

Re: Toshiba SA-735 schematic

this was so many years ago. however if someone needs the answer for this, the op amp 4558 drives the left and right channels, and heads up, SA-735 and SA-750 has the same amplifier design. few different resistors and capacitors, but same design on both PCB and schematic (for amplifier section)
