DIY Portable Speaker 35V Dual-Transistor Board

Hey guys, welcome back to the lab! I’m your host, the E-Doctor, and today we are doing some serious audio surgery. We’ve all seen those tiny Bluetooth speakers that cost a fortune but sound like a buzzy mosquito. Today, we are prescribing a cure for weak audio. We are building a high-voltage, hard-hitting 35V portable speaker powered by a super simple 2-transistor amplifier board." Don’t let the size fool you. Running this bad boy at 35 volts gives us massive headroom and surprisingly deep bass. Best of all? It costs less than a fast-food meal to make. Let's get to the operating table and see what components we need!"
