AS3340 (CEM3340) based VCO
UralTone VCO is AS3340 (CEM3340) based 8HP single oscillator.
The circuit follows basic datascheet 3340 example without any surprises. However there is some options for builder to choose from: Sync operation may be either selectable between hard or soft sync explained on 3340 data scheet or done as usual in 3340 based synths. PCB has also sinewave sharper so for example the inverted saw output may be replaced by this. Having both saw types are intended for LFO usage.
The VCO is easy to build but requires some calibration before usage.
Dials: Fine, PW, PWM, Lin FM
Switches: Octave, Sync
Connectors: CV in, PWM in, LIN FM in, Sync in, Saw out, Inv Saw out, Square out, Triangle out. All outputs are scaled to 0-10V
