Mini Transistor Audio Amplifier

When I was childhood, I always curious about how electronic circuitry works. I remembered when I wanted to build a transistor audio amplifier, but didn't have any supporting knowledge. Internet hadn't come to my place at that time, not like today. Well, I need some time to build and test all those circuits. Even if I can design a much more complicated circuit than a simple audio amplifier today, but recalling the romance of the past is always exciting. Someday, when knowledge is no longer needed for my work, I will use it for myself fun.
