Richard Brewster pointed out to me that actually the Oakley control PCB is
probably the one to use.  I do not have one yet, but it looks like the only
modification required would be to add one resistor to the summing node in 2
of the amps.  It also has a regulated 5 volt source on board for the bias.

I feel obligated to point out that if one plans to use a multimix board that
you need to have the latest version if you want to change the gain of the
reversing attenuator from unity.  Tony's original design used a singal amp
for that function.  While that is an efficient design, if you try and change
gain on it, you will find that the gain is changed in one direction and not
the opposite.  The new multimix boards use the 2 amp design.
