Questions
How big is the Riaa preamp PCB?
It measures 95.6 × 55.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Riaa preamp use?
80 parts, built around the SS310. 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 Riaa preamp KiCad files?
From the sjm42/electronics repository on GitHub, at the commit this page was made from: the board is riaa-preamp/riaa-preamp.kicad_pcb and its schematic blink-timer/blink-timer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Riaa preamp design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
