15v power amplifier walkman audio circuit
Introduction: The 15V powered Walkman uses a push-pull structure and uses a Vbe multiplier to optimize it.
The target is a Walkman audio power amplifier circuit powered by 15V. The input signal voltage is 0.2V and the output is 0.5W. The input port uses a sliding rheostat for volume adjustment. The common emitter amplifier circuit performs one-stage amplification. The NPN tube and the PNP tube work Push-pull output. Due to crossover distortion, a Vbe multiplier is used to eliminate the distortion effect.
