The Shehzad Electronics 200W D1047 Based Stereo Amplifier PCB is a high-performance audio solution designed for builders who want a balance of raw power and efficient cooling. Unlike mono boards, this stereo PCB provides two independent channels of audio, making it the perfect heart for a high-quality home stereo system or a custom-built powered speaker set.
Engineered for reliability, this board utilizes four NPN D1047 power transistors to deliver a combined 200 Watts of punchy, rhythmic audio. It is designed to operate on a $25V+25V$ Dual DC power supply, which strikes the ideal balance between high volume output and manageable heat levels for long-term operation. The board features a spacious $14.6\text{cm} \times 8\text{cm}$ layout, providing ample room for high-quality capacitors and ensuring low signal crosstalk between the left and right channels. With its clearly marked component values and professional-grade traces, this PCB is a favorite for hobbyists looking to create a durable, high-performance audio amplifier from scratch.
