Questions
How big is the Exp vintage vca PCB?
It measures 170 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Exp vintage vca use?
86 parts, built around the LM13700M, BC857BS and SS14. 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 Exp vintage vca KiCad files?
From the stash-s/synth-modules repository on GitHub, at the commit this page was made from: the board is exp-vintage-vca/exp-vintage-vca.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Exp vintage vca design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
