Anyone have Schematics for an Orion Extreme 375.2 amp?

What's wrong with it?

works when both channels are in phase, missing half the waveform when one channel is inverted for bridging!

Check the output of each of the op-amps to see if you can find one that has a clipped output.

Also check the outputs of the electronic potentiometer (DS1267 or similar).

If all appears OK on the op-amp and electronic pot outputs, you'll have to follow the trace back from the phase switch to see what's just before it in the circuit.

Do you mean that it's clipped when both have the same phase settings or when either/both are set to 180°?

nope not clipped, literally missing half the waveform. about 55-60% of the positive side of the waveform is there and no negative side. completely flat from the bottom of one positive peak to the next. So something is goofy. I had just enough time to test it yesterday. and wont have time to get back to it again for a few days so i thought in the meantime i would see if i can find a schematic.
