BackDiffer 500k Trimpot; tune to 1V out 10k NTC Thermistor <-- CV In - diode to U2-3 Clock In - diode to U2-3 - Clock rate goes down when resistance goes up, opposite to expectation. Glide fix - Single-step button (SW13) isn't producing a high enough voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a diameter between 16-19 mm: https://www.keyelco.com/product.cfm/product_id/826 Keystone #500, 12mm CR1220 battery holder, Keystone P/N 2462, https://www.keyelco.com/product-pdf.cfm?p=1027 1xAAA Battery Holder, 2479, Battery Type 3xAAA Keystone type 3000 coin cell battery CR-1025 coin cell cr1216 cr1220 cr1225 1xPP3 (9V) battery holder, Memory Protection Devices P/N.
