"I have written a slim monograph, Watson, on the 500 varieties of cigar ash..."

This book is a unique collection of detailed information on audio power amplifier design. The Sixth Edition is a major update with many chapters completely re-written, and a wealth of new material, adding more than 50% to the length of the book. Almost every chapter contains brand-new content. From any good/big bookshop, or via Taylor & Francis or Amazon. See links below.

This is a uniquely detailed guide to the theory and practice of audio power amplifiers, running from the elegantly simple mathematics of the differential pair to the practicalities of bolting down power transistors properly.

It includes the first complete explanation of the complex business of power amplifier distortion. It shows how the many sources of non-linearity can be eliminated or minimised, allowing amplifiers to be designed and constructed with performance that would have been thought impossible a few years ago. It provides information that is indispensable whether you are making one amplifier for the ultimate home system, or setting up a production line to make 10,000 units a year.


      THE CONTENTS INCLUDE:
	New Findings in amplifier design
	Science & Subjectivism
	The Performance Requirements
	How Negative Feedback really works
	The Eleven Distortion Mechanisms
	Diagnosis via distortion residuals
	The input stage: how it can cancel distortion
	The Voltage-Amplifier Stage
	Output stages
	Amplifiers and reactive loads
	Anomalous loudspeaker behaviour
	Interchannel crosstalk
	Compensation, Slew-Rate, and Stability
	Power Supplies and PSRR
	Class-A amplifiers, with a design example
	Class-G amplifiers
	FET output stages
	Load Invariant Power Amplifiers
	Thermal compensation and thermal dynamics
	Amplifier and Loudspeaker protection
	Grounding systems
	Mechanical design constraints
	Testing, Fault-finding and safety requirements

      NEW TO THE THE SIXTH EDITION:

	The characteristics of the audio signal
	The principles of distortion
	Feedback intermodulation distortion	
	The five-stage amplifier architecture
	Auxiliary amplifiers
	Non-switching output stages
