Análise de um amplificador de áudio padrão

Abstract

This work analyzes and assembles the 50W "Blameless" audio amplifier designed by Douglas Self in his book. The three stages of the amplifier, the feedback loop, and the mechanisms used to minimize distortion were studied. Only components available domestically were used, leading to modifications of some components from the original design. The prototype proved to be in line with Self's vision, demonstrating satisfactory performance in terms of distortion.
