Questions
How big is the FET Matching PCB?
It measures 42.2 × 42.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FET Matching use?
15 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 FET Matching KiCad files?
From the gtfields13/SharedPCB repository on GitHub, at the commit this page was made from: the board is PSX014 JFET Matching PCB/FET_Matching.kicad_pcb and its schematic PSX001_Neutrik_M-series_with_JST-PH/Neutrik M Series Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FET Matching design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
