<div>I just build the CGS vco. I combined other designs for this one, but I have built the CGS/EN/...fill-in-the-blank oscillator core before and it works good. </div>
<div> Did you build it on the breadboard first? </div>
<div> </div>
<div> Rebuild only the core circuit: </div>
<div>Expo convertor: use only the coarse freq. pot, leave all other cv inputs out. You might want to use two 2N3904 instead of the matched pair at first. That way, if somethings hooked up very wrong, you fry a 10 cent pair instead of a $5 pair. (I changed the 150K resistor connected to the first transistor((left one on scheme)) to a 1M)
<br>Core: this is built around the 3140 and 311</div>
<div>Sawtooth out: 1/2 of a TL072</div>
<div> </div>
<div>Get that to work and your home free.</div>
