I got no output on the right channel, or B or whatever. It is not in

I would look at those normal/bridging and stereo/parallel-mono switches,
as well as the level pots for the inputs. If there is an op-amp (to
bring a low input up) or maybe a resistor divider (to bring a high input
down) on that input board, check that too. A problem on the input board
might result in nothing getting to the power stages.
