My friend has built one replacement output board, and it works nicely, but
hasn't done a production run yet. I'll try to light a fire under him. I have
four Polarises that would make nice homes for his boards.

That probably wouldn't make a whole lot of difference. The real problems are
computer noise on the grounds and power supplies, digital noise coming in
through the error squawk line, and pseudo-random noise coupling from the
digital noise generator line into the output summing busses.
