Balanced Phono-Amps
I usually do not discuss audio books here, I used to publish reviews in Linear Audio. But this book is unique and needs some attention, so there!
Readers of Linear Audio will be familiar with author Burkhard Vogel; he heas written extensively about tube and low-noise design, and has several books published by the prestigeous Springer Nature publishers of Germany. This book, Balanced Phono-Amps has everything you might ever need to ask about the subject. In his tradition, Burkhard combines simulation, calculation and MathCad for cross-verification and confirmation.
Burkhard has kindly allowed me to post his preface here, which will give you a good insignt in his way of thinking and what to expect of the book. Recommended!
