Easiest bodge on the front Don't put R8 so close to R26 - D36/R47 too close Testing before powering up: Clock In Normal - 1k to U2-8 (AND NOT short to U2-10 Clock Rate - variable resist +6k between U2-8 and U2-9 Reset Sw - when pressed, short +12V and Reset In - diode to U2-3 Clock In - ~27K to U3-8? No, transistors maybe activate? Clock Out - Diode from rotary pin 13 - CV out, with probably +12v gates. Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). External reset via momentary push button. - Play.
