Description:
A 140W Power Amplifier Circuit Diagram is designed to deliver strong, distortion-free audio output for speakers or subwoofers. This high-power amplifier uses transistor or MOSFET stages for efficient signal amplification and provides clear, high-quality sound even at maximum volume. The circuit includes a preamp stage, driver transistors, and output transistors to boost low-level audio signals to a powerful 140-watt output. It’s ideal for home audio systems, DIY sound projects, or car audio applications. Learn how each stage works—from input filtering to biasing and heat dissipation—for the best audio performance.

🎯 Key Highlights:

Delivers up to 140 watts RMS output

Works on ±35V to ±45V dual power supply

High-fidelity sound with low distortion (THD 0.1%)

Efficient transistor design for better thermal control

Perfect for DIY audio enthusiasts and professional amplifier builds

🔧 Pro Tip: Use a proper heatsink and speaker protection circuit to enhance amplifier life and prevent overload.
