This extensive, 428-page, self-published hardcover book, is much more than another publication on tube amplifiers. As Jan Didden discovered, this book contains all the knowledge needed to check how an input low-pass filter must be dimensioned, how to investigate the different resistor types and their properties, capacitor types, which tubes to use, how to bias them, and construct the load lines, and even how to design low-noise power supplies. A one-stop resource for tube-based audio power amplifiers, and clearly a work of love!
