[sdiy] Balanced Modulator using a CA3280

[patchell]

    I found this circuit in my notes:
http://www.oldcrows.net/~patchell/archives/ca3280_12.html

    I thought I had a much nice drawing, but, this is all I found.  I
think this is what I built, but I am not too sure.  That is pretty old.
But, the one I built works pretty good, although, not as good as a real
balanced modulator.
