Questions
How big is the PreAmp PCB?
It measures 68 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PreAmp use?
41 parts, built around the TL072. 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 PreAmp KiCad files?
From the 3DMIN/pushpull-kicad repository on GitHub, at the commit this page was made from: the board is PushPull-preAmp/preAmp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PreAmp design in my own project?
Its repository states no licence, so its author keeps all rights: ask 3DMIN before reusing the design.
