Questions
How big is the QRPAmplifier PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the QRPAmplifier use?
133 parts, built around the 1N4744A and TIP42. 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 QRPAmplifier KiCad files?
From the profdc9/QRPAmplifier repository on GitHub, at the commit this page was made from: the board is PA/PA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the QRPAmplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
