Vacuum Tube Amplifier Basics

Finally, I found it, a book on building tube amplifiers and you do not need an advance degree in Calculus to understand the theory. Very clearly written in plain English and easy to understand. Having worked as an electronic tech for the past 30 years, I can read and understand complex schematic. This book is fantastically easy to understand and if you are afraid of electrical schematics, the author has provide detail drawing of how the circuit is layout with component by component placement. I have purchased several other books that spent page after page with charts telling me how a tube or a transistor will perform. That stuff puts me to sleep and those books are in a pile labelled I'll will never read them. This book is totally different and so easy to understand. Another excellent thing about this book is, if the author is explaining how a portion of a circuit works, the drawing he is referring to is located in the same paragraph and not on the next page!! I really enjoyed reading this book and hopefully you will too.

Well written and concise, hobbyist DIY amp builders will learn something here. Supplement with other online video resources to nail down critical concepts and build your confidence to build a great tube amp - great stepping stone for beginner to intermediate level electronics enthusiasts with some amp building experience. Two thumbs up! Basics? Well, perhaps, but plenty of good material here to reinforce what you think you may already know. You know who you are! EDIT: INVEST in this book, learn about tube amp power supplies and tube amplification stages, then actually BUILD an amp... that's where all of the excellent information in this book is intended to take you. Understand the components, the circuits, the building blocks and then build a really great tube amp. This book will actually get you there, if you are willing to put in the work. Worth every penny. Lots of illustrations of key concepts, along with circuits and wiring diagrams of some excellent HIFI and guitar amps. It has become my most trusted reference. Understand it. Build it. Love it!

This is a good book for someone who has little knowledge of electric circuits and no knowledge of how tubes do what they do. I did not need the basic electricity information but the tube information is kept deliberately simple so as to not overwhelm the reader. I now know a lot more about tube circuits and how they work. I can now follow the signal path through a wiring diagram. There is also a section on basic amplifier construction. I would recommend Vacuum Tube Amplifier Basics to anyone wishing to learn a little bit about the nuts and bolts of these devices.

If you just want to know how to make a Tube Amp for any purpose this is the book for you. It does cover introduction into electronics and then goes into specifics behind signal amplification. After that its directly into building simple yet effective amplifiers for practical use. 8 projects total using common tubes still available with source listings for the more difficult to find items such as audio and power transformers which can be purchased online and used for the projects presented in the book. Good Project book and well worth it overall.

I am a retired electronics engineer with very little knowledge of vacuum tubes. But in my 20's I used to build vacuum tube radios and amps, Heathkits, etc. I enjoyed that hobby so much I am resuming in retirement! I am reading several books all the time in my effort to learn, I look at schematics constantly, my wife thinks I'm having an affair with my parts and vacuum tube suppliers. I keep returning to this book because of one reason. The other books don't go into the actual test procedures like this book does. For example it shows how to hook up a harmonic distortion measurement test, frequency response test, and many other test procedures,old school using bench gear. Other books give you the theory and formulas, then they give you a few projects. Skipping entirely how to utilize my bench equipment, how to hook them up, how to interpret the results. It is hard to go from theory right into a build and you learn way more when you test your builds. This book gives theory, build AND testing procedures which is the area most other books neglect.

This book is as complete an introduction as you can find. It is suitable for readers who have no prerequisite knowledge of electrical engineering and even the mathematics start from a very basic level. Despite that, it tackles the source material in enough depth that one could design and build a Hi-fi amplifier after reading it. Warning: the information in this book is about tube amplifiers in general but the author seems to have more experience with Hi-fi amps than guitar amps. The one guitar amp design the book discusses is an odd one that mixes the clean signal with the distorted signal in parallel rather than running the input through all the tubes in series. The author said that is typical for guitar preamps because people don’t want to hear a 100% distorted sound. As far as I know, none of the major well known guitar amps are designed that way. So if you are really interested in guitar amps this book is a good start but then you will need to read other books to learn material specifically pertaining to guitar amps.

I’m a disabled Electrical Engineer. My career was primarily focused on wireless until an extremely rare joint disease forced me to disability...But being an Engineer, i had started my own company...mostly musical electronics repair, but I decided to start doing some design and construction of tube amplifiers...Being an Engineer, I skipped over the basic electronics section...but I HIGHLY recommend having a good understanding of electronics before trying to build or work on any amps ..Voltages can get quite high and even unplugged amps can be a hazard due to voltage stored in capacitors...This book points this out...I have a library of Amp design books but I reference this book often...Because I know where to find the information I need...It is very well laid out and doesn’t get too heavy on the math...but he does include the most vital equations and how they relate to a tube circuit..The book also covers areas of the circuit surrounding the tube and what changes in capacitance or resistance can do for your tone...This is a keeper!...Always on my bench

If you work on stereo or guitar tube amps and have a basic understanding of electronic principals this is a great book. The books focus is not a bunch of theory, but clear explanations of the circuits you will run into inside any vacuum tube amplifier. There are the necessary ohms law, power equations and tube bias and power charts, but that's it. No calculus or other fluff you don't need to know to build or repair a tube amp.

Basics, justement... on n'ira pas bien loin avec cet ouvrage qui en dit aussi long sur la visserie que sur l'électronique dans certains chapitres. Toutefois, cela peut constituer une approche suffisante pout un débutant. De plus, l'approche modulaire (pré, déphaseur, ampli) permet de faire sa propre salade avec un peu d'expérience.

Incluye explicación detallada e imágenes a blanco y negro. Viene todo en inglés

Concise and easy to understand... Of course you should have some basic knowledge of electronics to start and then the first section will be an excellent refresher. Looking forward to reading further on and possibly building one of the projects in the future. Really like the variety of projects includes.

Facile lettura e comprensione dei testi, trattato in modo esaustivo il problema delle valvole, ottime la preparazione elettronica di base per i dilettanti.

Es un libro muy detallado en cuanto a conceptos básicos pero imprescindibles y en muchas ocasiones olvidados o mal entendidos.Numerosos ejemplos y esquemas didácticos a la vez que muchos circuitos muy claros , concebidos con idea para realizar de forma practica sin errores. El texto en claro y conciso .Se aprecia claramente que el autor ha volcado su experiencia de años como profesional en esta materia . En el ultimo capítulo , el autor comenta una anécdota muy interesante que pone de manifiesto el porqué la amplificación por válvulas es tan asombrosa. Enhorabuena Sr Jurich .Espero que pronto nos pueda deleitar y enseñar de nuevo con otra publicación.
