15V walkman

Overview

The voltage is raised through the common emitter circuit, and then the current is amplified through the push-pull circuit composed of NPN and PNP. The voltage doubler pre-conducts the two transistors in the push-pull circuit and effectively avoids the influence of temperature, achieving power amplification.

Input signal voltage 0.2V, output 0.5W, volume adjustable
