Descripción del producto
Reseña del editor
The most up to date vacuum tube design book currently available. Packed with information...Loaded with projects...Nothing like it anywhere! Join Transcendent Sound’s Bruce Rozenblit as he takes you on a journey from the basics of tube circuitry, through advanced designs. Tubes and Circuits is a condensed engineering manual that teaches the theory and operation of vacuum tubes—as well as circuit design. In addition, five projects are included that you can build. Projects provide step-by-step design procedures, equations, schematics, parts lists, and photos to assist the hobbyist in construction. Build a state of the art, very low cost, 15W OTL (output transformerless) amplifier. Complete plans for a 300B OTL. Own most glorious 1 watt in all of audio. Pure single-ended, Class A sonic heaven. (See website for updates, www.transendentsound.com) A tube tester that tests virtually all current production audio and guitar amp tubes—can be user modified to test any tube; a simple device used for testing most octal based rectifier tubes and a tube analyzer used for manually determining tube constants and bias currents. Tubes and Circuits provides all design procedures and equations necessary to allow readers to create their own designs. Practical methods are revealed—all built upon a solid theoretical base. Bruce Rozenblit shares his decades of experience designing hi-end tube audio equipment. Nothing has been held back. Topics include the essential physics required to understand circuits. Explains in detail what electricity is and how it works. Shows how DC current flows and behaves through resistive elements. Detailed information on AC circuit theory, reactive elements, and how they affect signals. What inductance is and how it is created. How components are used to create networks and interact with each other— includes transformer theory. Shows how feedback works and how best to use it. Reveals in detail the chemical and physical processes of how vacuum tubes function, generate current, age, and deteriorate. Shows how the electric fields inside vacuum tubes cause them to work. Demonstrates what tube constants are and how to use them. Shows how to use tube characteristic charts to derive the tube constants used in design equations. Explains load lines and their application. Detailed operation and all design equations for virtually all of the tube circuits used in high-end audio. Includes single-ended and push-pull transformer coupled output stages. Basic information on power supply design and function. All of the theory is put to use and made practical in the project chapters. Learn how to design OTL amplifiers. Anyone that uses vacuum tubes, from the hobbyist, the musician, to the design professional, would benefit from Tubes and Circuits.
Biografía del autor
Bruce Rozenblit is the President and Chief Engineer of Transcendent Sound, Inc., which specializes in vacuum tube audio kits for the DIY audiophile. He specializes in OTL (no output transformer) amplifiers that produce maximum fidelity. He holds a U.S. patent in amplifier design. He has been professionally involved in the audio industry since 1996, a lifelong audiophile and started working with tubes by 1985. This is his third book on audio technology.

Más de medio libro explica la física básica de la materia, la del electrón y por fin, a más de medio libro, empieza a hablar de algo parecido a un amplificador a válvulas. casi sin información sobre fuentes de alimentación.... Montajes protegidos intelectualmente, con presumiblemente falta de información sobre los componentes necesarios y, probablemente con algún dato erróneo... No voy a conectar ninguno de mis altavoces a estos esquemas. La mayoría son OTL sin protección... no ha complido en absoluto las expectativas que indicaba.
No es en absoluto recomendable, ni para usuarios avanzados ni para principiantes.

Finally on page 149 he gets to the good stuff -some basic valve circuits, but it's a whistle-stop tour that lasts 55 pages. Power supplies get just 7 pages.
Then he presents his pride and joy -a couple of OTL projects (although the interior photos look distinctly amateur -all rats nests). Also a simple tube tester is included. I wouldn't dare connect my speakers to one of his OTLs mind you; they have no offset protection at all.
Anyway, it's a weird book. It seems like a beginner's physics/electronics book that suddenly has a couple of exotic tube amp circuits bolted on the end! With precious little tube electronics in the book, it certainly is NOT "the most up to date and comprehensive vacuum tube design book currently available."
And all his battery symbols are backwards.
Perhaps an audiophile, in need of a homemade tube tester and interested in the design and construction of OTL audio amplifiers, would find this book to be a valuable asset; but to those, like me, who simply want to know more about traditional tube-amplifiers (with output transformers), its assets were greatly outweighed by its cost. At $12.95 I would have kept it......but at $32+ I returned it for a refund (which did not include postage either way).
In conclusion: I strongly suggest that prior to order, you carefully study the overview of contents (available on Amazon), to be sure that this book is really what you're looking for. Even though it was reviewed in magazines like Vintage Guitar, it is primarily focused on rather esoteric OTL hi-fi amps.
