Default AutoTek SX5750 Diag

Hello all,

Seeking some assistance on diagnostics of an old Autotek SX5750. I have contacted Autotek in an attempt to get schematic sheets, although was informed none were available as this amp is quite outdated........

Issues are:

Channels 1/2 funtion properly, no issue.

Channel 5 is dead no audible sound/tone whatsoever.

Channels 3/4 operate on very low (almost not audible) volume if 3/4 xover selector is switched to "Bandpass", although function properly on high pass/full range selections. Have removed board for inspection, no signs of smoked parts.

Can anyone offer a system schematic on this amp, or possibly diagnostic ideas?
