there is a small omission in the build manual.
When assembling the square part of the VCO, the manual states:
Once you've verified that sawtooth wave generation is working, you can continue on to the square wave generator.
Disconnect all external power and solder in the following parts:
10K reisistor R34
100K resistor R35
22K resistor R45
0.01uF capacitor C10
1uF capacitor C11
2SA733 PNP transistor Q8
Omitting R36 (which is in the picture tho'), it gave me a little bit of problem, but not much Thanks to James at Willzyx
