The 48 most common of 52 parts.
It measures 70 × 80 mm and has 2 copper layers, 1.6 mm thick.
52 parts, built around the 2SA1016KG-AA, 2SB631KF, 2SD600KE and 2SB817. 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.
From the Rsalin/Amplifier-PCB repository on GitHub, at the commit this page was made from: the board is rotel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Rsalin before reusing the design.
