[sdiy] Voltage controlled panner

[J C]

Can anyone point me to a compact circuit for a voltage controlled
panner?  This would pan one input through two outputs via a single
control voltage.
I am working on one with two CA3080 vca's and an inverting circuit on
the control voltage for the second VCA.  Ideally, though, at 50% CV,
each VCA would output 100% as opposed to 50% in my current circuit. 
Looking for some other ideas...
