Check before you build · 3 values the reader of this schematic was not sure of

C6: designator printed twice (100uF bias filter and 2.2uF CH1 VCA cap)
C3/C10: labels sit by pin 3 but the only drawn capacitor is across pins 6-7, read as the timing capacitor
SW1/SW2: drawn as two-pole three-position F/2-F-2F selectors
