Questions
How big is the Amplifier PCB?
It measures 48 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Amplifier use?
30 parts. 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 dingjamesj/electronic-trombone repository on GitHub, at the commit this page was made from: the board is KiCad/Amplifier/Amplifier.kicad_pcb and its schematic KiCad/Amplifier/Amplifier.kicad_sch. 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 dingjamesj before reusing the design.
