- Potentiometers: I use the Alpha (D-shaft) 9mm fom THONKICONN (https://www.thonk.co.uk/shop/alpha-9mm-pots-dshaft/)
- Jacks: I use the PJ398SM from THONKICONN (https://www.thonk.co.uk/shop/thonkiconn/)
- Switch: I use the Mini toggle switch from THONKICONN (https://www.thonk.co.uk/shop/mini-toggle-switches/)
- All mounting holes are M3 (3.2mm), and pick an offset that you feel good with
See Bill Of Material for a full list of material and where to solder the components
In general: use the Bill Of Material and solder each component. Start from the lower components and go to the higher ones.
PCB Tested: Yes
Built: Yes
Issues:
- Schematic was wrong and had inverted inputs on the TL074's
- 2mm sockets are a bit too small and required layering to make it high enough
- Capacitors were on the front, making the height of the bottom board too high
