Other Notes
Daughterboard Heights
- From notes on How to Make Great Looking Modular Front Panels - Part 3 Module Circuit Board Layout
- The absolute maximum of other boards I've seen is 111,5 mm and the TipTop Happy Ending Kit offers a space of 112,5 mm
- 114.8mm measured between 3U Synthrotek rails
- 128.5mm - 114.8mm = 13.7mm both sides, 6.875mm per side
- 111.5mm daughtercard, leaves 8.5mm clearances top/bottom
Part Orientations
- For pots with built-in pointers, pot pins go down for pointer to go up at center point
Front Panel Jacks
Alpha Pots
Long Shaft with pointers
- These pots have the same footprint as Alpha/Synthrotek metal shaft pots, but with a longer shaft
- They are knurled with a white pointer, so they don't need any knobs
- They are suitable for many different Eurorack projects
- .05W
- 20% Tolerance
