4069 VCO

The 4069 VCO was designed by René Schmitz, schematics can be found on his site.

I really like the 4069 VCO of several reason: My version of the 4069 vco contains a slightly modified boost stage for the saw output as shown to the right, i have this here because it's incorporated in the breadboard layout of the 4069 vco found below.
