(1)adjustment at VC=0.5VCCUse voltmeter to measure the voltage of point K to ground and adjust R2 to make VK=0.5VCC.(2)adjustment of quiescent current IC1,IC2Minimize the resistance of RW first.when the power source is available,add sinusoidal signal to input end and use oscillograph to measure voltage waveform of load RL,and then,adjust RW until the moment that crossover distortion of output waveform disappears.
