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 book 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 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 book a rich and useful source of information.

In seinem leidenschaftlichen Plädoyer für die Nutzung von Sonnenenergie wendet sich der Autor an technisch nicht versierte Leser. Der Autor von Photovoltaik für Quereinsteiger hat drei klare Botschaften: Es ist ziemlich einfach, eine Photovoltaikanlage erfolgreich in Betrieb zu nehmen. Die notwendigen Kalkulationen dazu, ob sich eine Solaranlage lohnt, passen auf einen Bierdeckel. Elektrischer Strom kann mit Photovoltaik schon heute für 3,5 Eurocent pro Kilowattstunde erzeugt werden. Allerdings nur tagsüber und auch nicht überall auf der Welt (aber an sehr vielen Orten). Das Buch erklärt, wie man zu marktüblichen Preisen Anlagen bauen kann, die zu unschlagbaren Niedrigstpreisen Strom liefern können. Es wird erläutert, wie man Anlagen abhängig vom Standort kalkulieren muss. Dabei beleuchtet der Autor in leicht verständlichen Worten die physikalischen Grundlagen der Gewinnung von Energie durch Photovoltaik und erklärt, wie eine Solarzelle prinzipiell arbeitet. Die grundsätzlichen Bestandteile einer Photovoltaikanlage werden so erklärt, dass sie auch von Laien verstanden werden. Ausführlich geht der Autor auf die richtige Wahl von Batterien zur Speicherung des gewonnenen Stromes ein. Potentielle Fehler- und Gefahrenquellen beim Auf- und Ausbau finden ebenso Berücksichtigung. Das Buch richtet sich dabei an Privatpersonen und an Projektbetreiber, die Strom für den Eigenverbrauch erzeugen möchten.

From Rubbing Amber to Swiping Glass "The story of electricity, told one connection at a time."Why does rubbing amber attract dust? How did we go from that curious effect to a world where screens respond to a single touch? And how did we get from mysterious sparks to tiny chips packed with billions of transistors? For centuries, electricity puzzled and fascinated those who encountered its curious effects—long before it even had a name. From the earliest observations of static charge to the complex electronics that shape our lives today, this book traces the gradual, and often surprising, story of how humanity came to understand and harness this powerful force. This book offers an engaging and accessible account of the people, ideas, and inventions that transformed electricity from a scientific curiosity into the foundation of our digital age. Along the way, you’ll meet a host of inquisitive minds—some famous, others less so—whose persistence and creativity helped unravel the mysteries of the natural world and gave rise to the technologies we now take for granted. Covering everything from Leyden jars and batteries to transistors, microcontrollers and the internet, this book presents a clear and enjoyable overview of electronics and its relatively short, yet rich, history. Whether you have a technical background or simply a curiosity about how things work, From Rubbing Amber to Swiping Glass offers a thoughtful look at how far we’ve come—and a gentle nudge to wonder what might come next.
