2 watt amlifier circuit diagram The following is made for a 2 watt audio amplifier. This amplifier has a wide frequency response, low harmonic distortion about 1.5%, and is capable of driving an 8 ohm speaker to output levels of around 5 watts with slightly higher distortion. The amplifier operates in Class AB mode; the single 470R preset , PR1 controls the quiescent current flowing through the BD139/140 complimentary output transistors. This amplifier has a S/n ratio of 115dB at 1kHz. Overall gain is provided by the ratio of the 22k and 1k .
