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
Eurorack Vertical Pots
Op Amps
- From this site
- The TL084 Op-Amp is very similar to TL074 but has high noise immunity and better offset characteristics.
- The TL074 has lower noise figure, so is better for AC signals.
- The TL084 has lower offset, so is better for DC signals.
- The TL084 has better DC performance (low offset) and the TL074 has better noise/distortion performance.
- You can use TL074s on the audio paths, TL084s on the control paths.
- TL074 Datasheet
- TL084 Datasheet
- The TL074 is $0.75 in qty 10 (on Mouser)
- The TL084 is $0.55 in qty 10 (on Mouser)
- The TL072 and TL082 are both about the same price as each other, but are more expensive than the quad parts

- SyntherJack - DIY Synths
- BEFACO - Kits
- Kassutronics DIY Store
