A hands-on guide to vacuum tube audio amplifier technology and do-it-yourself projects The TAB Guide to Vacuum Tube Audio: Understanding and Building Tube Amps is ideal for hobbyists interested in building high-end audio amplifiers. The book is composed of two principal elements: the theory and operation of vacuum tubes and audio amplifier circuits, and practical projects for the experienced experimenter. The author covers the theory of tubes and amplifier circuit design from a classical perspective, drawing from time-proven principles and techniques. At the same time, this classical approach to amplifier design reflects and incorporates new technologies that preserve the many sonic benefits of the "tube sound." The projects included give you the chance to construct high-end audio amplifiers and related equipment at a variety of levels of sophistication, power output, and construction preferences. The TAB Guide to Vacuum Tube Audio Provides a straightforward tutorial on vacuum tube principles and audio circuit design Reviews the tradeoffs that engineers must make in designing an audio amplifier and helps you tailor particular circuits to meet your personal objectives Features a suite of projects for the hobbyist, including preamplifiers and power amplifiers, using a variety of construction approaches Includes full details for all projectsdrawings, photographs, and parts lists Provides a practical understanding of the principles of vacuum tube operation Contains the latest, most up-to-date methods for optimizing vacuum tube audio performance.
