(Normalling) | | R9, R11, R13 | 3 | A1M | **Potentiometer, 9 mm vertical board mount | | J6, J10, J11 | 3 | 22k | Resistor | | U3 | 1 C10, C14 too small for film; is film needed? - Smaller cap (476nF?) for C1 - Ceramic 104s for C10, C14, might be fine, might introduce intermittents - Don't put R8 so close to R26 - D36/R47 too close Testing before powering up: Clock In - diode to U2-3 Clock In Normal - 1k to U2-8 (AND NOT short to U2-10 - 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 socket Reset Socket to U3-3 = capacitor measurement roughly 15nF.
