Place the LM386 onto the center of a breadboard or prototyping PCB.
= Target peak-to-peak ripple voltage (typically kept under 0.5V for audio)
Discharges large power supply capacitors before touching them. 2. Project 1: The LM386 Low-Voltage Mini Amplifier practical audio amplifier circuit projectspdf
Practical Audio Amplifier Circuit Projects Andrew Singmin is a comprehensive guide for intermediate to advanced electronics hobbyists interested in building usable audio systems. The projects are structured to help readers transition from basic building blocks to complex audio inventions, such as pre-amplifiers and power amplifier combos. Amazon.com Core Project Highlights
Building an audio amplifier requires attention to detail. Even a tiny mistake can introduce annoying background hums, buzzes, or ruin your components. Preventing Ground Loops and Hum Place the LM386 onto the center of a
This project uses a complementary pair of high-power Toshiba power transistors.

The hobbyist sweet spot. It biases the transistors slightly "on" to eliminate crossover distortion while maintaining relatively high efficiency.
