PB101 Sync VCO

The Sync VCO is actually a pair of oscillators, a normal voltage controled oscillator and an other oscillator that syncronice the first one. It comes with a triangle and a square wave output.
In changing the capacitores one can change the range for the oscillators. The value should be between 10 and 50nF.
