2W Amplifier:   Amplifier operates in Class AB mode;  single 470R preset resistor controls  quiescent current flowing through  BD139/140 complimentary output transistors. Adjustment here, is a trade-off between low distortion and low quiescent current. Typically, under quiescent conditions, standby current may be 15 mA rising to 150 mA with a 50 mV input signal. A simulated frequency response is ... (added 6/06)
