Voltage gain Av ≈ Rc / Re = 3.3kΩ / 470Ω ≈ 7 (without bypass). With bypass capacitor, Av ≈ Rc / re (re = 25mV/Ic) → ~50 typical.

To successfully build the projects outlined in this guide, assemble the following tools and electronic components. Required Tools

The offers a compact solution for stereo sound. A Hi‑Fi Stereo Audio Amplifier project PDF from Electronics For You describes a 4 W per channel amplifier that runs off a 9 V DC supply, using only a few ceramic and electrolytic capacitors. The PCB layout and veroboard alternatives are provided, along with a calibration procedure using a metal screwdriver. Note that pin 7 of the IC must be connected to a 5 V source (via a 7805 regulator) to disable the mute function.
