Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large 17.5mm panel hole+snip off pin, add holes for the four plastic clips sliders: 3mm above panel, ample thunkicons: probably too short without extra spacers, use mini toggle pushbuttons: ample space above 11.75mm (existing 1p12t rotaries, use 11.25mm holes to PCB edge 11.32mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 37-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 9.9mm mounting-holes-distance 25mm mounting-hole-offset 25mm 9-pin D-Sub connector edge mount solder cup male x-pin-pitch 2.77mm mounting holes to PCB edge 4.9399999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 37-pin D-Sub connector, solder-cups edge-mounted, female, x-pin-pitch 2.77mm, distance of mounting holes to PCB edge 11.32mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 9-pin D-Sub connector.
