This book enables readers to understand, create, reconfigure and personalize high-end, audiophile quality amplifiers. Following a step-by-step approach to design, with little maths and lots of know-how, it starts with a brief review of electronic fundamentals relevant to valve amplifiers, simple stages, compound stages, linking stages together, and finally, complete designs.

The new material included in this Fourth Edition ensures this book will stay at the top of any audio designer's or enthusiast's reference list.

 What's new within the chapters:

Chapter 1: Charge amplifiers

Chapter 2: Additional circuits, semiconductor constant current sources expanded

Chapter 3: Entire new section on noise

Chapter 4: Lots of new measurements to explode or explain audio folklore

Chapter 5: Astonishingly quiet, but cheap and simple HT supply

Chapter 6: New power amplifier

Chapter 7: New hybrid balanced RIAA stage, attenuator law faking

VA3's focus was on distortion, but in VA4, focus is pushed towards background noise reduction. If that wasn't enough, there's more explanation, more measurements, more references, and plenty of new one-liners, any one of which might save hours of trouble.
