Balanced Phono-Amps

This extensively reworked 2nd edition of the book includes ten new chapters. It also features an updated discussion of simulation software tools, covering topics such as simulating complex and / or expensive amplifier structures with the free LTspice software by developing a broad range of additional simulation models, especially those for triodes and transformers.

The book adopts the structure used in The Sound of Silence books, with the first part, Basics - Calculations and Simulations, providing deep simulation-triggered insights into the gain and noise mechanisms of differential amplifiers, BJTs, resistors, and triodes. The second part then discusses the RIAA Phono-Amp Engine II, describing all the necessary design, simulation, calculation, construction and measurement processes for this multi-functional MC amplifier.

The third part, Knowledge Transfer, presents new ideas on draft designs of the linear low-noise MC input stages (also an extremely low-noise one) and a range of practical measurement tools. Additionally, it includes a chapter on MM amplifiers and their noise production, and offers some surprising solutions. The brand new and extensive chapter on all the simulation models developed and used in the book rounds-out the voyage through the jungle of compromises, allowing best-in-class balanced MC phono-amplifiers to be produced.

Lastly, the book also features an extensive index, and free downloads of all Mathcad worksheets are available on Springer's Extra Materials website (https://extras.springer.com/?query=978-3-319-36890-0).

Autorentext
Burkhard Vogel achieved the degree Diplom-Ingenieur (Telecommunications) from Darmstadt University of Technology, Germany, in 1973. He then decided to follow a general management career path in the high-tech and IT industry in Germany, Switzerland and Austria. His passion for music and music systems made Mr Vogel an expert in Phono-Amps and Vinyl Technology. In addition to "Balanced Phono Amps" he wrote the RIAA-phono-amp designer's guide "The Sound of Silence" and the triode-reference "How to Gain Gain"
