Questions
What parts does the Amplifier use?
38 parts, built around the NE5532, BD138 and BD139. 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 Amplifier KiCad files?
From the sonic2000gr/schoolspace repository on GitHub, at the commit this page was made from: the board is Schematics/Amplifier/Amplifier.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask sonic2000gr before reusing the design.
