It measures 95 × 45 mm and has 2 copper layers, 1.6 mm thick.
24 parts, built around the NE5532, TIP141 and TIP146. 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 demianmozo/amp_AB repository on GitHub, at the commit this page was made from: the board is amp_AB.kicad_pcb and its schematic amp_AB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask demianmozo before reusing the design.
