Ok it appears that someone worked on this amp before and have the outputs in the wrong spots ..

This amp uses C4467 and A1694's as outputs..

Does the A1694s control the positive or negative rail??

The C is generally on the positive rail but that's not always the case.

Find the terminal of the output transistor on the rail for the other channels and install the same transistors on the corresponding rail for each of the outputs in the defective channel.
