Back* Bourns PTL series, such as: https://www.mouser.com/ProductDetail/Bourns/PTL30-15O0-105A2?qs=fV9UsjselOEqdQiKFAm%2Fog%3D%3D (A1M, orange LED, 30mm travel, 15mm shaft) * https://www.mouser.com/ProductDetail/Bourns/PTL30-15R0-103B1?qs=X8nz4ozed5glbMOCRmYKzw%3D%3D (B10K, red LED, 30mm travel, 15mm shaft https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15R0-103B1/3781301 (red B10K) and https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15O0-105A2/7314942 (orange A1M) The first two groups should be changed by adding +5V, and both trigger/gate and CV on the streets of the main (cylindrical or conical) knob shape, without the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation. C1 is too small for film; is film needed?
