About this SiteThis site supports The TAB Guide to Vacuum Tube Audio in a number of ways, including the following: • Parts lists for the projects described in the book as downloadable Microsoft Word or Excel files For more detailed information about the book see the Table of Contents and the Preface. |
Corrections and ErrataUnfortunately, errors can creep into a book as it works its way through the writing, editing, production, and printing process. The following items are known issues from the first printing: • Page 56, Figure 3.5. Two traces are given for three different cathode temperatures. The upper curve for each trace should be dashed, as described in the figure cutline. This replacement figure shows the dashed lines correctly. My apologies for these errors. If you see anything else that doesn't look right, please let the author know. |

A Personal CommentA funny thing happened after I finished the book and put a couple of the projects (the stereo preamp and the 25 W stereo amplifier) in my home office: I began collecting (well, recollecting) vinyl records. |

Regretting it now, I got rid of my LP collection many years ago (OK, decades). CDs were new and modern and convenient and sounded better...or so it seemed. Viewed with some perspective now, there were some very good vinyl pressings, and some bad ones too. Fortunately for tube enthusiasts, many record labels have begun re-issuing 180 gram vinyl LPs. Between the newly issued and old stock records, the selection of LPs available today is not bad. So, after collecting some LPs, I began playing them. Much to my surprise my wife (and sometimes even the kids) sat down to listen. It has since become a bit of a ritual to pour some good wine (not for the kids, of course) and put on an LP. There is a certain appeal in listening to a great classic LP out loud—not just ear buds—in a group setting. The ultimate endorsement came when my wife suggested I move the equipment to the living room so we can turn it up really loud. |
Tube Talk at NABEach year, the National Association of Broadcasters holds its annual convention in Las Vegas. During the show, more than a hundred highly technical presentations are given on leading audio, video, and transmission technologies. I have attended the NAB Convention for the past 30 years, and given perhaps two dozen talks. In 2012, I had the opportunity to do a short presentation on the topic of vacuum tubes and vinyl records at the SBE Ennes Conference. The presentation was intended as a broad overview of the subject matter. The presentation was titled "The Tube Sound: Fact or Fiction?" I hope you enjoy it. Update: At the invitation of the Wisconsin Broadcasters Association, I gave an expanded version of the NAB talk at a Society of Broadcast Engineers meeting during the WBA Broadcasters Clinic, October 9-11, 2012, in Madison. This version goes into a little more detail, and led some interesting question-and-answer discussion afterward. (download Acrobat file) |
