Practical Audio Amplifier Circuit Projectspdf -

More efficient than Class A, but suffers from "crossover distortion" as the signal transitions between the positive and negative output transistors.

Coupled with the art of good PCB layout and the discipline of systematic testing, you possess the complete toolkit. Whether you're building a simple headphone amp, a powerful hi-fi system, or a custom guitar pedal, the resources are out there. The path is clear, the knowledge is waiting, and the world of audio amplification is yours to explore.

Connect all audio grounds to a single physical point on your circuit board. This is called a "Star Ground." Avoid looping ground wires in a circle. practical audio amplifier circuit projectspdf
