It takes a while to get into this book mostly talk about circuits and applications.
This one is not for me and above what I expected from author.
This takes a lot of understanding in tubes & circuits to get through this one.
The book is not written for the Hobbyist who is looking for schematics or wiring diagrams.
It gave an insight in the tube and circuits aspect.

So far it's great. Sharpen your pencil and be prepared for an intense warmup of electronics math!

HASH(0x9ec40b1c) out of 5 stars Circuits 101 Nov. 7 2013
By david Boyd - Published on Amazon.com

I was one of the first persons to buy this book so I have had a lot of time with it. I have been involved in tube electronics for over 40 years and have built kits and modified existing tube preamps and amplifiers but never fully understood how the different components worked with each other or how to size them. This book answered almost all of my questions in a simple straight forward way. One thing about this book, a lot of information is contained in a very few words so every time I reread a section I locate information that I thought he did not cover. Worth every penny.

HASH(0x9f09b42c) out of 5 stars Who is this book for?? Feb. 26 2014
By Valve Nut - Published on Amazon.com
I never thought I'd say this, but this book spends TOO long on the fundamentals. Out of 268 pages, 148 cover elementary phyiscs and electronics, starting with stuff like speed, velocity, force, and work. It eventually gets up to a fairly lengthy discussion of the construction of valves, even going on to cathode chemistry and solid state conduction, and the potential distribution inside various tubes. Interesting, I suppose, but practically useless.

Finally on page 149 he gets to the good stuff -some basic valve circuits, but it's a whistle-stop tour that lasts 55 pages. Power supplies get just 7 pages.

Then he presents his pride and joy -a couple of OTL projects (although the interior photos look distinctly amateur -all rats nests). Also a simple tube tester is included. I wouldn't dare connect my speakers to one of his OTLs mind you; they have no offset protection at all.

Anyway, it's a weird book. It seems like a beginner's physics/electronics book that suddenly has a couple of exotic tube amp circuits bolted on the end! With precious little tube electronics in the book, it certainly is NOT "the most up to date and comprehensive vacuum tube design book currently available."

And all his battery symbols are backwards.

HASH(0x9eda633c) out of 5 stars Build your own June 19 2013

Bruce Rozenblit is a superb engineer who has designed amazing amplifiers for DIYers. I bought this book chiefly as I wanted the designs for his latest and greatest amps (I have built 3 others, 1 from his earlier book 'Audio Reality' and 2 from his website). Every one has been a marvel. If you want some of the best value in audio available and don't want the hassle of sourcing your own parts, buy his kits. If you like to do everything your self, buy the book and implement his designs. You won't be sorry.

HASH(0x9ec27444) out of 5 stars Not Quite What I Expected or Needed.......... Dec 26 2012
By The Jaundiced Eye - Published on Amazon.com
Verified Purchase
After reading a favorable review of this book in Vintage Guitar magazine, I ordered a copy to enhance my knowledge of guitar amplifier circuits. Upon arrival I was disappointed to find that my $32+ had purchased a rather thin paperback book a little larger than a Reader's Digest. Then, quite frankly, the text and projects disappointed even more. After a lengthy review of high school physics, the author covers some interesting material (circuits) and then digresses into (for me) less compelling topics such as output-transformerless (OTL) hi-fi amplifiers and several projects that were of absolutely no interest, including the construction of a tube tester.

Perhaps an audiophile, in need of a homemade tube tester and interested in the design and construction of OTL audio amplifiers, would find this book to be a valuable asset; but to those, like me, who simply want to know more about traditional tube-amplifiers (with output transformers), its assets were greatly outweighed by its cost. At $12.95 I would have kept it......but at $32+ I returned it for a refund (which did not include postage either way).

In conclusion: I strongly suggest that prior to order, you carefully study the overview of contents (available on Amazon), to be sure that this book is really what you're looking for. Even though it was reviewed in magazines like Vintage Guitar, it is primarily focused on rather esoteric OTL hi-fi amps.

HASH(0x9ed5c6a8) out of 5 stars Audio DIYer's "must-have" July 30 2012
By CharlieM - Published on Amazon.com
The long awaited follow up to "Audio Reality," this new book "Tubes and Circuits" is more in-depth and loaded with tons of useful and specific information. For anyone interested in electronics in general and tubes in particular. All presented in a manner in which even "non technical types" can follow. Although written for anyone, this is a "must-have" edition for any Do-It-Yourself (DIY) audio enthusiast, especially "tube-o-philes" or "tube-o-holics" if for no other reason than the included projects alone. Some of the projects presented are world class, tube-based, ingenious OTL (Output-Transformer-Less) amplifiers with printed curcuits and parts lists included. If you're into tube based audio this is the only book you'll ever need and one you'll definately want in your pile/stack/stash of literature. I already consider it reference material. Highly recommended!
