Questions
What parts does the Phono preamp use?
38 parts, built around the NE5532. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Phono preamp KiCad files?
From the sim82/audio_circuits repository on GitHub, at the commit this page was made from: the board is phono_preamp/phono_preamp.kicad_pcb and its schematic phono_preamp/phono_preamp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phono preamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask sim82 before reusing the design.
