Designing High Fidelity Valve Preamps

Designing High-Fidelity Tube Preamps is a comprehensive guide to the design of small-signal, tube-based amplifiers. This book examines in unprecidented detail the inner workings and practical design of small signal stages, volume and tone controls, RIAA equalisation, power supplies and more. Aimed at intermediate to advanced-level hobbyists and professionals it teaches the principles of low-noise, low-distortion tube design, through easy-to-read explanations and minimal math. With over 400 diagrams and figures, and hundreds of real measurements of real circuits, it asserts itself as an essential handbook for any tube amp enthusiast.

Designing Tube Preamps for Guitar and Bass is the most comprehensive guide to the design of tube-based preamplifiers for musical instrument use, in a single volume. From the input to the phase inverter this book discusses in detail the inner workings and practical design of every part of a conventional guitar preamp, including the use of triodes, pentodes, tone controls, effects loops and much more. This second edition is fully revised and includes four new chapters covering noise, signal switching, topology, and grounding. Aimed at intermediate-level hobbyists and circuit designers, it explores how to manipulate distortion and maximise performance for the perfect tone. With easy-to-read explanations, minimal math and over 250 diagrams and figures, it is an essential handbook for any tube amp enthusiast!

Designing Power Supplies for Valve Amplifiers is a unique guide to the operation and practical design of linear power supplies, especially for valve equipment. Audiophiles, guitarists and general hobbyists alike will find this book an invaluable source of detailed information on transformers, rectifiers, smoothing, high-voltage series and shunt regulators, and much more. Although this book is not intended for the beginner, learning is encouraged through practical design, and concepts are introduced at a basic level before the reader is accelerated to the stage of high-performance design, with over 200 circuit diagrams and figures. Numerous practical circuits are included, for high-voltage stabilisers, heater regulators, optimised bias circuits, high-voltage supplies using 'junk box' parts, and even audio power control for guitar amplifiers. An essential handbook for any valve amplifier enthusiast!

Morgan Jones' Valve Amplifiers has been widely recognised as the most complete guide to valve amplifier design, modification, analysis, construction and maintenance written for over 30 years. As such it is unique in presenting the essentials of 'hollow-state' electronics and valve amp design for engineers and enthusiasts in the familiar context of current best practice in electronic design, using only currently available components. The author's straightforward approach, using as little maths as possible, and lots of design knowhow, makes this book ideal for those with a limited knowledge of the field as well as being the standard reference text for experts in valve audio and a wider audience of audio engineers facing design challenges involving valves. Design principles and construction techniques are provided so readers can devise and build from scratch designs that actually work. Morgan Jones takes the reader through each step in the process of design, starting with a brief review of electronic fundamentals relevant to valve amplifiers, simple stages, compound stages, linking stages together, and finally, complete designs. Practical aspects, including safety, are addressed throughout. The third edition includes a new chapter on distortion and many further new and expanded sections throughout the book, including: comparison of bias methods, constant current sinks, upper valve choice, buffering and distortion, shunt regulated push-pull (SRPP) amplifier, use of oscilloscopes and spectrum analysers, valve cooling and heatsinks, US envelope nomenclature and suffixes, heater voltage versus applied current, moving coil transformer source and load terminations. The practical guide to analysis, modification, design, construction and maintenance of valve amplifiers The fully up-to-date approach to valve electronics Essential reading for audio designers and music and electronics enthusiasts alike

There is a wide field of tasks left that can only be satisfyingly attacked with the help of old-fashioned analogue technology, and one of the most important are amplifiers for analogue signals. The strongly expanded content of the second edition of "the sound of silence" leads to affordable amplifier design approaches which will end up in lowest-noise solutions not far away from the edge of physical boundaries set by room temperature and given cartridges - thus, fully compatible with very expensive so called "high-end" or "state-of-the-art" offers on today markets - and, from a noise point of view in most cases outperforming them! With easy to follow mathematical treatment it is demonstrated as well that theory is not far away from reality. Measured SNs will be found within 1dB off the calculated ones and deviations from the exact amplifier transfer won't cross the ± 0.1dB tolerance lines. Additionally, the book presents measurement set-ups and results. Consequently, comparisons with measurement results of test magazine will soon become easier to perform. This new edition includes a new chapters about reference levels, Noise in Amp Input sections, Humming Problems, and much more.
