    The audio amplifier was invented in 1909 by Lee De Forest when he invented the triode vacuum tube (or "valve" in British English). The triode was a three terminal device with a control grid that can modulate the flow of electrons from the filament to the plate. The triode vacuum amplifier was used to make the first AM radio. Early audio power amplifiers were based on vacuum tubes.

    THE MJR7-Mk5 LATERAL MOSFET CLASS-AB POWER AMPLIFIER. Tested at 4V into a 7R5 load to check for crossover effects the 1kHz distortion was mostly second harmonic under -120dB (0.0001%), achieved with only 100mA quiescent current. Power output is around 30W into 8ohms with a single 60V supply, or higher voltages can be used for up to about 100W.
