Questions

What parts does the AmpyFil use?

20 parts, built around the TL084, LM358 and 74HC4051. 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 AmpyFil KiCad files?

From the impatrq/Apolo repository on GitHub, at the commit this page was made from: the board is PCB del proyecto/AmpyFil.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the AmpyFil design in my own project?

Its repository states no licence, so its author keeps all rights: ask impatrq before reusing the design.
