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 Tape preamplifier Guitar and GP preamplifier High impedance mic preamp Low impedance mic preamp Bass and treble tone controls Simple graphic equaliser Scratch and rumble filter Loudness filter Loudness control Basic audio mixer Audio limiter Small (300 mW) audio power amp 10 watt audio power amp High power (70 watt) power amp using power MOSFETS
