Audio Amplifier Projects

If you are an electronics or audio enthusiast you will find in this book a wide range of useful audio amplifier projects. You won't need any detailed electronics knowledge either as all the projects can be constructed on simple circuit board.

Each project features a circuit diagram, and an explanation of the circuit operation. There is in addition a stripboard layout diagram and all constructional details are provided along with a shopping list of components.

All the projects are designed for straightforward assembly on simple circuit board.

Circuits include:

• RIAA amplifier
