I'm gonna have to get my hands on some Electronotes. I've been hearing about
them for years but have never seen a copy.

So what I need is another Ring Modulator and a quadrature oscillator to
create on modularly...

ken,
well, 2 balanced mod circuits (or is it one, i can`t recall
at the moment for
sure, oops, :^( ), some 90 degree phase shift networks,
assorted summers and
a carrier oscillator. i recall that electronotes had one
designed quite a few
years ago. using that as a starting point should be
feasible. especially with
the analog devices ic`s for ring modulators. much better
than 595`s or simple
ota circuits.
best,
dave
