New tri-VCO design

[patchell]

    Pretty nice.  I am tempted to send you a THAT120 to substitute for the
MAT03 and 2n3906 in your current mirror.  I would be currious to know if one of
these works just as good.  I am not positive, but I think the THAT120 is a lot
cheaper (but not as well matched as the MAT03).
