Questions
How big is the Classd amp PCB?
It measures 180 × 133.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Classd amp use?
176 parts, built around the IR2184S, TL072, LM358 and LT1016CD. 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 Classd amp KiCad files?
From the prydin/classd-amp repository on GitHub, at the commit this page was made from: the board is classd-amp.kicad_pcb and its schematic classd-amp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Classd amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask prydin before reusing the design.
