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.

From SRPP and Mu-Follower to OTL Designs Tube amplifiers suffer from distortion. Fortunately, circuits such as the SRPP amplifier, mu-follower, and beta-follower produce minimal distortion even at output voltages of 50 to 100 Vpeak. These designs are often published with errors. Without a sound understanding of the theory, it is easy to arrive at a flawed design. In the first section of this book, we investigate the origin of distortion, while in the second we investigate the design of and SRPP and a mu-follower. On the internet we can find the most exotic designs. Evaluating them teaches us that these designs often make matters worse rather than better. In the chapter on incorrect SRPPs and mu-followers, we sometimes see bizarre and misguided designs where using a simple single-triode amplifier would perform much better. Push-pull output stages also exist. A great number of them are examined, and their similarity to the SRPP is discussed. This is done especially with the help of the theory behind the OTL based on the ‘mother’ of all OTLs, the Philips HF303. Finally, attention is given to frequency characteristics and technical matters such as the supply voltage and the filament power supply. To illustrate these points, there are a few designs covering the subjects discussed. This book presents much new theory that has not been published before. It is often an eye-opener, showing that many things have a beautiful and unexpected simplicity.

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.
