Certainly your VISIO drawn schematics are a thing of beauty in this book, especially when compared to the LTSpice ones (see fig 19.1 for an example). The square wire junction nodes give that a somewhat clunky feel. Overall I really appreciate the visual (rather than mathematical) feel of this book. Its reminiscent of that other great 'bible' in electronics, Horowitz and Hill.
I have a suggestion for adding to your website Bob. I'm guessing the VISIO schematics don't produce LTSpice compatible netlist output, so why not maintain a cache of LTSpice versions of the schematics shown in your book on your website? I don't suggest you spend time inputting the schematics again, but how about inviting readers to upload their own or send them to you by email? This way you'll facilitate experimentation with your circuit examples and potentially have some worthwhile reader contributions to the 2nd edition 😉
The evaluation version is limited in the number of components, that is, as far as simulation is concerned. AFAIK, this limitation doesn't apply if used as schematic capture only pgm.
BTW, it seems that VISIO is from micro$hoft. That says enough already. However, the size of the installation file is 293MB. That says more than enough. Bloatware 🙁
Hi Abraxalito,
This is a good idea, and is pretty much in line with what I have planned for the supplemental book material that I'm going to put up on the web site. What I plan to put up is as follows:
- reasonable models of the transistors I used in the numerous simulations referred to in the book. This is not a large collection, but is enough to simulate the ready-to-run simulations I will provide. These models will not be perfect (none are), but they will have been sanity checked by me and at least tweaked somewhat if not done largely from scratch.
- simulations of most of the examples in the tutorial LTspice chapter 19.
- some number of amplifier simulations.
- probably some other simulations that were done for the book, such as some output stage simulations.
What gets put up will of course be a function of time.
Many of the schematics that were drawn with VISIO actually started as LTspice simulations, such as virtually all of those in Chapter 3, so those simulation files already exist and just need to be cleaned up a bit before I put them up.
Cheers,
Bob
I got my copy on Wednesday here in Poland.
But I canceled my order at amazon.co.uk and put a new order at amazon.US.
I'm starting to read the book, and I love your writing style.
Good job Bob
I went through the book but not yet fully in depth. It is what I was looking for.
The only place where I would like to see some addition is in the part related to the front end input stage and Vas
It is always difficult to make a presentation which well balanced between maths à la textbooks and technical descriptions à la Self or Sloan.
I would suggest to add on your site some more technical desciptions of the front ends and Vas with relevant equations; it would be nice to see also descriptions with pro and cons of fully symetrical designs, fully ballanced design, folded cascode ones and better analysis of complementary Vas which is called in the litterature class AB amplifier.
Presentation of poles zeros graphs with respect to current, output impedance with respect to current for these stages would be very usefull.
I would love to see these aspects treated in the same simple way ( back of the envelope calculation) but audio oriented as Sansen in his book " Analog design essentials"
The presentation could be like he is doing, power point slides including circuit schematics and simple design equations for each circuit
Power point slides with more in depth equations of the different topologies would be a tremendous add on to the best book on audio amplifiers.

Why????????Hey Bob
I already have the "High Power Audio Amplifier Construction Manual" by Slone. Why should I buy your book?
Thanks,
Ted

Self gets it wrong also:
What's wrong with this picture? 🙂
I've not bought Self's or Slone's books, but I did buy Bob's.
A rather rude comment by you gripracer, how do you know that Bob's book does not have significantly more material?
There is the matter of Randy's book being written 11 years ago. Usually that's a big problem with any "how-to" or technical publication, regardless of authorship or the quality of information.I already have the "High Power Audio Amplifier Construction Manual" by Slone. Why should I buy your book?
