(J19/J18); the schematic is incorrect Ins: 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 rate goes down when resistance goes up, opposite to expectation. Schematic fixes: Trim 5mm from vertical for both panels, to make thoroughly clear what is believed to be a contributor!
