Amplifier class AB 1w

Using amplifier modules is modern, quick and easy but it teaches nothing about how they work. Here is a Class AB amplifier made from individual components which will deliver several watts of power into an ordinary 8 ohm speaker. Gives hands-on learning about cross-over distortion, bootstrapping, complementary pairs, and push-pull. Detailed explanations given.

D.C. input : 9 - 18V
Current consumption < 500 mA
Idle current ~ 30 mA
