To many people, the thermionic valve or electron tube is history. However, whether it is nostalgia, interest in the technical parameters, the appeal of a gleaming amplifier chassis with softly glowing valves, respect for the technical know-how of an earlier generation, or perhaps the firm conviction that the sound of a valve cannot be bettered, it is a fact that the valve is making a come-back. The book contains, apart from construction projects for preamplifiers, power amplifiers, and two amplifiers for musical instruments, information on the operation of electron tubes, while the first chapter gives a short history of the valve.

Although it is true that accurately calculating electronic circuits can involve complicated formulas, for the electronic hobbyist it is not necessary to perform at the level of an electrical engineer. With some basic knowledge it is possible for the hobbyist to design and build vacuum tube audio amplifiers that perform well. This book covers basic electronics related to vacuum tube amplifiers, an elementary guide for understanding and working with vacuum tube amplifier circuits. Sections cover electronic and audio information that are concise with many examples and illustrations. Vacuum tube amplifying circuits are explained in simple terms without complicated math. Math is primarily basic math and a few simple formulas all solvable with a standard calculator and presented with examples. A table of component values for the popular 12AX7 in various operating parameters simplifies amplifier stage design. The first section of the book contains more detailed technical basic electronic information. Sections two through four are more casual in presentation and include pertinent information from section one. Included in this book are eight project circuits with parts list and component layouts for a Buffer Line Amplifier with 25db gain, 6V6SE Monoblock Amplifier, Triode Balanced/Unbalanced Input, Tone Control Stage, Cathode Follower Output, and Turntable Pre-Amplifier. Also included are a 6V6SE Stereo Amplifier and Guitar Amplifier project circuits with component layouts.

(Book). There's a huge amount of hype and mythology surrounding tube amplifiers in the guitar world. For years, experts have argued over the tiny details of exactly how they do what they do, and how their various components interact. What's undeniable is that, far more than being just a "loudness booster," the unique combination of tubes, capacitors, resistors, and transformers in these amps can contribute enormously to the quality of sound derived from any electric guitar. In this thorough and authoritative book, Dave Hunter cuts through the marketing hyperbole, and the blind faith, and supplies all the information you need to choose the right amp, and get the best from it. The book also features exclusively conducted, in-depth interviews with leading figures in the tube amp-building world including Ken Fischer, Mark Sampson, and Michael Zaite and even provides full instructions on how to construct your own high-quality tube guitar amp from scratch.

The 34 chapters of the 2nd edition of How to Gain Gain give a detailed insight into a collection (54) of the most common gain producing, constant current generating possibilities, and electronic noise creation of triodes for audio pre-amplifier purposes. These chapters also offer complete sets of formulae to calculate gain, frequency and phase responses, and signal-to-noise ratios of certain building blocks built-up with this type of vacuum valve (tube). In all cases detailed derivations of the gain formulae are also presented. All what is needed are the data sheet valve characteristic figures of the triode's mutual conductance, the gain factor and the internal plate (anode) resistance. To calculate frequency and phase responses of gain stages the different data sheet based input and output capacitances have to be taken into account too. To calculate transfer functions and signal-to-noise ratios for any kind of triode driven gain stage, including all its bias setting, frequency, phase, and electronic noise influencing components, example Mathcad 11 worksheets as an essential simulation tool for each chapter allow easy follow-up and application of the respective formulae. Free download of all worksheets is guaranteed from the editor's web-site.

Explains the whys and wherefores of toroidal output transformers at various technical levels, starting with elementary concepts and culminating in complete mathematical descriptions. In all of this, the interactions of the output valves, transformer and loudspeaker form the central theme. Next come the practical aspects. The schematic diagram of a valve amplifier often appears to be very simple at first glance, but anyone who has built a modern valve amplifier knows that a lot of critical details are hidden behind the apparent simplicity. These are discussed extensively, in connection with designs for amplifiers without output powers ranging from 10 to 100 watts. Finally, the author gives some attention to a number of special valve amplifiers, and to the theory and practice of negative feedback.

This book moves beyond general principles of tube amplifier design to carry out an intense examination of one of the most famous circuits of the rock era. The author begins with the 5F6-A's relatively simple triode preamps (bypassed cathode resistor, unbypassed cathode resistor, and cathode follower) and then progresses through the mathematically challenging tone stack, long-tailed-pair phase splitter, and push-pull power amp. Every formula for every tube is derived in all its gory detail, including voltage gains, input and output impedances, frequency responses, dynamic power supply loads, and interactions with the rest of the system. The author's methods include the classic load lines and composite characteristic curves of Frederick Terman and the Radiotron Handbook as well as more modern techniques like linear regression and the Discrete Fourier Transform. Special attention is paid to quantifying the push-pull amplifier's nonlinear response and to analyzing power supply voltage sag as it reacts over time.The Bassman 5F6-A circuit has inspired guitar amplifier designs for over four decades, so sharpen your pencil, fire up your calculator, and find out what makes this amp rock!Richard Kuehnel is a member of the Circuits and Systems Society of the Institute of Electrical and Electronics Engineers.
