[sdiy] CA3280 VCA Design

[Rob Keeble]

Hi,
I have a tube of CA3280's which I plan to turn into dual VCA's, however I
can't find a circuit design on the web...so I have cobbled one together -
which is here (37k GIF) - mainly using ideas from the SCI Prophet 5..

Before I put this on the breadboard, any changes I should make?
Audio and CV ins are 0 to +10V standard. VCA is linear, unity gain, and
should't invert signals. Only one VCA shown...

Many thanks
Rob
