UMA 1502 schematic

How can I obtain schematics (not flow charts!) for the UMA 1502 mixer? Anyone have them?

1502 mixer shows no output signal

Just recieved a used UMA™ 1502 MIXER/AMPLIFIER- 4 input. Hooked up the 4 ohm output. Get response (green light) on channel one. Sps lights, but no signal showing for output. No sound from speaker. Any solutions?
