Projects

Other Notes

Daughterboard Heights

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

  • Synthrotek store page
  • 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
