Circuit Principle and Design Ideas: The entire circuit can be divided into four main sections: the power supply, signal input, amplification stage, and output stage. Each part plays a crucial role in ensuring the overall performance and stability of the amplifier. The power supply section is responsible for providing a stable voltage to all components, which is essential for maintaining consistent operation. The signal input section handles the incoming audio signals and prepares them for amplification. The amplification stage uses transistors to boost the signal strength, while the output stage ensures the final signal is delivered efficiently to the speakers or other devices. This design is based on a single-ended Class A amplifier configuration, known for its high fidelity and low distortion. However, it also has some limitations, such as lower efficiency compared to other amplifier classes. Despite this, the simplicity and clarity of the sound make it a popular choice among audiophiles and hobbyists. Below is the circuit diagram for the 20W transistor-based single-ended Class A power amplifier, showing the layout and connections between components.
