The function of transistors in radios is straightforward. Sounds are recorded through a microphone and turned into electrical signals. Those signals travel through a circuit, and the transistor amplifies the signal, which is subsequently much louder when it reaches a speaker. Convincing manufacturers that this basic concept would work on mass.

Step 1: Get Started. The only thing you need for this project is an AM/FM transistor radio, an older model that has a physical adjustment for tuning rather than digital. This will be a wheel or slider that changes stations. The only tool you should need is a small screwdriver. Open the radio by removing all the screws.

The Transistor Radio. In 1954, the world was a far different place than it is now. Almost anything electronic required vacuum tubes — an invention dating back to the beginning of the 20th century that had yet to be improved on. Vacuum tubes were the only way of performing many electronic functions — such as amplification and rectification.
