This simple amplifier delivers good sound quality with a power output of approximately 10 to 14 Watts and operates on a supply voltage of about 34 to 36 Volts DC. It requires a preamplifier due to its limited advanced features. The design necessitates substantial heat sinks, a robust transformer, and a significant power supply with careful wiring; however, it is remarkably reliable and produces excellent sound. The zener diode effectively filters out noise from the power supply, allowing for a ripple voltage of only about 10mV, which is quite acceptable. The input signal is amplified, enabling the zener diode to function adequately, but any residual noise may still affect the power stage. The buffer stage utilizes a C945 transistor, the driver stage employs an MJE340, and the booster stage incorporates a TIP3055. All transistors used in this amplifier are NPN type.

The described amplifier circuit is a straightforward yet effective design suitable for audio applications. The power output range of 10 to 14 Watts makes it ideal for small to medium-sized speakers, providing sufficient amplification without excessive distortion. The supply voltage requirement of 34 to 36 Volts DC indicates that this amplifier is designed for higher performance, allowing it to deliver better sound quality and dynamic range.

The use of a preamplifier is crucial in this circuit, as it enhances the input signal before it reaches the main amplification stages. This is particularly important given the amplifier's basic design, which lacks advanced features that could otherwise improve performance. The substantial heat sinks are necessary to dissipate heat generated by the transistors during operation, ensuring reliability and longevity of the components.

The zener diode plays a vital role in maintaining the stability of the power supply by filtering out voltage spikes and noise. This helps in achieving a clean output signal with minimal ripple, which is essential for high-fidelity audio reproduction. The specified ripple voltage of approximately 10mV indicates that the power supply is well-regulated, contributing to the overall sound quality.

The circuit's architecture consists of three main stages: the buffer stage, the driver stage, and the booster stage. The buffer stage, utilizing the C945 transistor, ensures that the input signal is properly matched to the driver stage, preventing signal loss. The MJE340 in the driver stage amplifies the signal further, preparing it for the final boost provided by the TIP3055 in the booster stage. This configuration allows for effective amplification of audio signals while maintaining sound integrity.

Overall, this amplifier design is a practical solution for those seeking a reliable and efficient audio amplification system, with the potential for excellent sound quality when properly implemented.This simple amplifier does sound good quality Power output about 10 - 14 Watts with Supply voltage about 34 - 36 Volt DC. It requires a preamp in the function of it hasn`t got much advance. It requires cumbersome heat up sinks and a great transformer and a enormous power supply and alert wiring, but taking part in the bottom it is enormously regul

ar and it sounds very good. The zener diode rubbish every wave future from the power supply, But you still barely aspire a ripple of 10mV be very successful. The swell triumph the input is enlarged, so the zener diode gets free of with the intention of, but whatever swell in attendance is wish still catch the power stage.

The Buffer Stage using transistor C945, Driver Stage Using MJE340 and Booster Stage using TIP3055. The Transistor are using NPN transitor.
