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... More > 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!< Less
Research studies within the process industry routinely indicate that the fluid control valve is responsible for 60 to 70% of poor-functioning control systems.
This book ‘The Complete Valve... More > Primer – a definitive guide’ is a complete in-depth manual covering all aspects of valve technology and includes more than 140 explanatory drawings – clearly showing the construction of a wide range of valves that includes: control valves; shut-off valves; check valves; and pressure relief and safety valves. A large section is also devoted to covering the fundamental principles of converters, actuators, and positioners.
Readers are presented with an insight into flashing, cavitation, noise generation, leakage problems, a complete overview of valve sizing, and the correct procedure for calculating the spring ‘wind-up’.
Routine maintenance and repair issues are also covered, as well as diagnostic methodologies for testing for deadband/hysteresis, stick-slip and non-linearity;and signature analysis.< Less
Have you ever wondered if there is a difference between horizontally and vertically applied butterfly valves? In this eBook, Mr Günter Öxler, from Festo Didactic GmbH & Co. KG, explains...
