Understanding and Using Them Effectively What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope. Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back. In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals? Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.

Quite unintentionally a one-page story on an old Heathkit tube tester in the December 2004 edition of Elektor magazine spawned dozens of ‘Retronics’ tales appearing with a monthly cadence, and attracting a steady flow of reader feedback and contributions to the series. Since launching his Retronics columns, Elektor Editor Jan Buiting has never been short of copy to print, or vintage equipment to marvel at. This book is a compilation of about 80 Retronics installments published between 2004 and 2012. The stories cover vintage test equipment, prehistoric computers, long forgotten components, and Elektor blockbuster projects, all aiming to make engineers smile, sit up, object, drool, or experience a whiff of nostalgia. To reflect that our memories are constantly playing tricks on us, and honoring that “one man’s rubbish is another man’s gem”, the tales in the book purposely have no chronological order, and no bias in favor of transistor or tube, microprocessor or discrete part, audio or RF, DIY or professional, dry or narrative style. Although vastly diff erent in subject matter, all tales in the book are told with personal gusto because Retronics is about sentiment in electronics engineering, construction and repair, be it to reminisce about a 1960s Tektronix scope with a cleaning lady as a feature, or a 1928 PanSanitor box for dubious medical use. Owners of this book are advised to not exceed one Retronics tale per working day, preferably consumed in the evening hours under lamp light, in a comfortable chair, with a piece of vintage electronic equipment close and powered up.

Es ist heute nicht mehr ganz einfach, ein Buch über Röhren zu verfassen, da in den letzten Jahrzehnten viel Wissen über dieses interessante Gebiet verloren gegangen ist. Genau das aber ist einer der Gründe, warum dieses Buch geschrieben wurde. Der Autor hat sich zur Aufgabe gemacht, die für den Einsatz von Röhren im Audiobereich bedeutsamen theoretischen und praktischen Kenntnisse zu bündeln und darzustellen. Der Verfasser stützt sich dabei auf seine eigene und umfassende Erfahrung, die er in den vielen Jahren vor der breiten Einführung von Halbleitern durch intensive Auseinandersetzung mit der Röhrentechnologie gewonnen hat. Selbstverständlich werden in den Schaltungsteilen, die nicht unmittelbar im Signalweg sitzen, die Vorzüge zeitgemäßer, aktiver elektronischer Bauteile wie Transistoren oder ICs gezielt ausgenutzt. Hinzu kommt die bevorzugte Verwendung hochqualitativer, moderner Ringkerntransformatoren. In den ersten Kapiteln dieses Bandes wird auf Produktionsverfahren und die Arbeitsweise von Röhren eingegangen, anschließend werden deren Grundschaltungen ausführlich besprochen. Das gewonnene Wissen erfährt in den folgenden Abschnitten eine theoretische Vertiefung bei der genaueren Betrachtung von Endstufen, Klangregelungen usw. Zudem wurden zwei gesonderte Kapitel aufgenommen, die sich mit Klirrverhalten und Verzerrungen, Rauschen, Mikrofonie und anderen Störgeräuschen befassen. In vier weiteren Kapiteln werden vollständige Verstärker-Entwürfe und die Dimensionierungsberechnungen aller Baugruppen im Einzelnen unter Hinweis auf die zugehörigen theoretischen Überlegungen der vorherigen Kapitel vorgestellt. Dabei wird deutlich, dass Röhrenverstärker physikalischen und mathematischen Gesetzen gehorchen, weit verbreitete Legenden und Mystifizierungen dagegen nichts zur Erhellung der funktionellen Zusammenhänge beitragen. Im Übrigen findet der Leser viele nützliche Hinweise bei der konkreten Umsetzung der jeweiligen Schaltung in ein funktionierendes Gerät und Hilfestellungen für die messtechnische Überprüfung der Resultate.

A Combat Guide against E-waste and Throwawayism This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste. E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project. Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.
