Nope, you might be missing the -15V that drives the X DAC though....
Or the X DAC might be blown. I don't know the BZ board very well, so
I'm not sure what else is the the analog section of this board, but it
might be in some sort of a problem with an amplifier or voltage follower
in the X section.
Do you have an osciliscope? Can you trace the output of the X DAC to where
it hits the edge connector to see where you lose -X?
