From the project
Power Amplifier based on Michael Chua's C300 amplifier
This is a PCB layout by Daniel Marks based on Michael Chua's C300 amplifier which can be found at:
This is a project designed to be a good quality amplifier that is achieves good quality distortion (< 0.1% THD at 10 kHz and 300 W per channel max), and is both educational (to study for electronics engineering and hobbyist use) and archival (to be useful long into the future, or "future proofed"). This is a layout from 2020 but it is assumed that decades into the future, relatively few bipolar transistor models will be available as through-hole and discrete component electronics become ever…
