4-watt audio power amplifier using an ECG1102 as an AF driver. The ECG1102 is a 5-pin module. The two bias pots in the output stage should be adjusted to provide an idle current of 15 mA. Total current at maximum output is 450 mA. Voltage gain is 28 dB. Bandwidth is from 20 hertz to 30 kilohertz (courtesy GTE Sylvania Incorporated).
