Imagine your dad is old. Sure, he hears anything weak sound. How do you do? You are an electronics inventor, right? Yes, you can try to make a tool. To help him back to listen to great music again. This project is small, use only one 1.5V battery. Using normally components you can buy in stores near you.
You are All Power Amplifiers circuits lists.
Do you love music? Imagine we can build a power amplifier system. Sound good, doesn’t it? Here are many circuits. For example, Audio amplifiers, bridge amplifiers, Using transistors or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls.
