Like the simple amplifier in the previous section, this project starts with the solderless breadboard version of our Three Penny Radio, and adds an amplifier. But this amplifier has several important improvements over the simple one transistor amplifier.
This project uses an integrated circuit with 10 transistors to amplify much better with much less power drain on the batteries than our simple amplifier.
