Open source audio amplifier

The power supply has a stable symmetrical +/- 40 V to ensure optimal performance.
Maximum power (THD 1%) approaches 100 W into 8 Ω load and 190 W into 4 Ω load (see measurements). All parts are through-hole, making it easy to build the amplifier. The design is completely symmetrical.
