100W Audio Amplifier Transistor by BDW84 , BDW83



100W Audio Amplifier Transistor by BDW84 , BDW83

The circuit works from a symmetrical ±40 VDC power supply and draws a maximum current of 2.6 A. The input circuit of the amplifier is a differential amplifier built around Q4 and Q5 that employ DC feedback thus preventing any DC voltage from appearing across the speaker with the usual destructive results. Q11 acts as a current source and ensures that the input stage draws a constant current of 1 mA.
