Elektor Digital Modern High-End Valve Amplifiers (E-BOOK)
Valve Amplifiers are regarded by many to be the ne plus ultra when it comes to processing audio signals. The combination of classical technology and modern components has resulted in a revival of the valve amplifier. The use of toraidal-core output transformers, developed by the author over the past 15 years, has contributed to this revival. The most remarkable features of these transformers are their extremely wide frequency ranges and their very low levels of linear and nonlinear distortion. This e-book (pdf) 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 this apparent simplicity. These are discussed extensively, in connection with designs for amplifiers with 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. In summary, this e-book offers innovative solutions for achieving perfect audio quality. Do-it-yourself builders, as well as persons who want to gain a deeper technical understanding of the complex world of audio transformers, valve amplifiers and audio signal processing, will find this e-book a rich and useful source of information.

Elektor Digital Vanderveen Trans Tube Amplifiers (E-book)
Menno van der Veen is well known for his research publications on tube amplifiers used in audio systems. In this book he describes one of his research projects which focuses on the question of whether full compensation for distortion in tubes and output transformers is possible. In the past, a variety of techniques have been developed. One of them has largely been forgotten: trans-conductance, which means converting current into voltage or voltage into current. Menno van der Veen has breathed new life into this technique with his research project titled “Trans”. This book discusses all aspects of this method and discusses its pitfalls. These pitfalls are addressed one by one. The end result is a set of stringent requirements for Trans amplifiers. Armed with these requirements, Menno then develops new Trans amplifiers, starting with Transie 1 and Transie 2. These DC-coupled, single-ended tube amplifiers have unusually good characteristics and are suitable for hobbyist construction. Next the Trans principle is applied to amplifiers with higher output power. A trial-and-error process ultimately leads to the Vanderveen Trans 30 amplifier, which optimizes the features of Trans. The characteristics of this amplifier are so special and unique that Menno believes he has struck gold. To ensure that variations in tube characteristics cannot interfere with optimal Trans behavior, Menno makes use of simulations and comparison with other amplifier types. This book reads like an adventure story, but it is much more – it is an account of solid research into new ways to achieve optimal audio reproduction.

Elektor Digital E-Book: Designing Tube Amplifiers EN ANGLAIS
This book focuses more on practical aspects than on theory, and it has an contemplative nature, as though the author were viewing amplifiers from above. Knowledge elements are integrated and placed in the context of a broad overview. Even now tube amplifiers still sound great perhaps better than ever before. In part that is because we now have access to modern components such as toroidal output transformers, extremely high-quality resistors and capacitors, and many sorts of wire with good acoustic properties. Modern audio sources, such as CD players, and the latest top-end loudspeakers also enable us to appreciate how well tube amplifiers reproduce music even better than before. This new book from Menno van der Veen looks at tube amplifiers from more than just a theoretical perspective. It focuses primarily on the design phase, where decisions must be taken with regard to the purpose and requirements of the amplifier, and it addresses the following questions: How do these aspects relate to subjective and objective criteria? Which circuits sound the best, and why? If you want to develop and market an amplifier, what problems should you expect? What are the significance and meaning of measurements? Are they still meaningful, or have they lost their relevance? Thanks to the enormous processing power of computers, we can now measure more details than ever before. How can these new methods be applied to tube amplifiers? Previously it was sufficient to measure the frequency range, power and distortion of an amplifier in order to characterize the amplifier. Are these measurements still sufficient, or should we start measuring according to how we hear, using real music signals instead of waveforms from signal generators? The author sketches a future where amplifier measurements that conform to our sense of hearing enable us to arrive at new insights. This book focuses more on practical aspects than on theory, and it has an contemplative nature, as though the author were viewing amplifiers from above. Knowledge elements are integrated and placed in the context of a broad overview.

Elektor Digital High-End Valve Amplifiers 2 (E-book)
Nobody has any doubt that valve amplifiers produce a remarkably beautiful sound. They have a lively, deep, clear, and expressive sound, and dynamically they do not appear to have any limitations. The author investigates, in a systematic theoretical approach, the reasons for these beautiful properties. He develops new models for power valves and transformers, thus enabling the designer to determine the properties of the amplifier during the design process. Mathematical models for the coupling of power valve(s) and output transformer are provided. These will generate new insights in a special kind of distortion: the dynamic damping factor distortion (DDFD). With mathematical models in the complex domain, especially the properties at the limits of our hearing range (from 20 Hz to 20 kHz) are investigated and the minimal stability criteria for the amplifier are formulated. The often-applied negative feedback in amplifiers is extensively modelled and discussed in relation to our hearing appreciating. And after all this theory a fine selection of special amplifiers is presented and discussed. You will notice in this book that the author not only writes about amplifier technique, but tells about the way the development of valve amplifiers can have an influence on your daily life; even the usefulness of patents is discussed. Summarizing: new theories and solutions for perfect audio with valve amplifiers. Not only the professional and the DIY-er but everyone who wants to understand valve amplifiers will read this book with much pleasure.
