Valve Amplifiers 4th Edition by Morgan Jones


Valve Amplifiers 4th Edition PDF Download Ebook. Morgan Jones describes all stages of design so that you can create your own wonders. Jones is an ex-BBC engineer with a cool writing style and you'll find it a no-pain education. It is an extremely well-written book, containing a wealth of information that all audio designers and builders will find useful.

Many still hanker after the traditional warm valve sound from a hi-fi, and if you're handy with a soldering iron and not afraid of HT voltages, the Jones' book could keep you amused for hours. Filled with designs, tips, and information on every aspect of valve power amplifiers, a basic knowledge of electronics and metalwork is all you'll need to get the most from this (relatively) ancient technology.

This guide is a market leader for one simple reason: in this specialist area it is recognized as the most complete guide to valve and vacuum tube amplifier design, modification, analysis, construction and maintenance. It is truly the all you need to know guide, and enables audio and circuit designers to succeed with their valve amplifier designs and projects.

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.

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.
