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.

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.

When Raspberry Pi 4's system on chip (SoC) achieves a certain temperature, it lowers its operating speed to protect itself from harm. As a result, you don't get maximum performance from the single board computer. Fan SHIM is an affordable accessory that effectively eliminates thermal throttling and boosts the performance of RPi 4. It's quite easy to attach the fan SHIM to Raspberry pi: fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no soldering required! The fan can be controlled in software, so you can adjust it to your needs, for example, toggle it on when the CPU reaches a certain temperature etc. You can also program the LED as a visual indicator of the fan status. The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode. Features 30 mm 5 V DC fan 4,200 RPM 0.05 m³/min air flow 18.6 dB acoustic noise (whisper-quiet) Friction-fit header No soldering required RGB LED (APA102) Tactile switch Basic assembly required Compatible with Raspberry Pi 4 (and 3B+, 3A+) Python library and daemon Pinout Scope of delivery Fan SHIM PCB 30 mm 5 V DC fan with JST connector M2.5 nuts and bolts Assembly The assembly is really simple and almost takes no time With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers. Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts. Push the fan's JST connector into the socket on Fan SHIM. Software With the help of Python library you can control the fan (on/off), RGB LED, and switch. You'll also find a number of examples that demonstrate each feature, as well as a script to install a daemon (a computer program that runs as a background process) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.
