He talks briefly about the same, the other leg of R21 to the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that. Consider: 1 simple on/off switch/button/knob/etc. - 2 momentary pushbutton switches 1 rotary switch, 5+ positions - 10 ohms between U1-14 and U2-1 when off, more like 1M ohms when off - Glide attenuator (B10k) (join two left pins from below Pots, 2-pin: - Glide, manual (A100k) (two left pins, from below - Glide, manual (A100k) (two left pins, from below Clock rate goes down when resistance goes up, opposite to expectation.
