Resistor for sync; placed everything on PCB sandwich, making some final-ish decisions about connecting to front panel and Pin 1, steel retention lug, vertical PCB mount, retention spring instead of the main (cylindrical or conical) knob shape, without the two resistors **Corrected:** Updated C5 and C14 with more panel layout ideas left_rib_x = thickness * 2; right_rib_x = width_mm - hole_dist_side - thickness; // draw a horizontal cylinder around the knob?
