Al: Yes, Rozenblitt's book has its flaws, and the author's biases are evident here and there (though in that regard it is not nearly as didactic as is Morgan Jones' book). And yes, it has advertising in the back section, and for that reason only, I think it's a bit overpriced. However, the first three chapters should supply anyone who reads them carefully with a basic understanding of how tubes work and then how basic circuits work. At minimum, they impart enough information to enable one to read other texts that address the same material in greater depth. I can say this, because I was in Jef's position at one time a few years ago, and I feel that TBGTA was a good starting point for increasing my knowledge base. If one has the patience to go searching for "old college textbooks", then I suppose one could save some money. But most textbooks that even mention thermionics are now approaching a half century in age, and are not so easy to find. (I also know this from personal experience, having haunted a local second hand bookstore for months in vain, in search of anything relevant to vacuum tube electronics. As you may know, original copies of The Radiotron Designer's Handbook or the Valley and Wollman book on Vacuum Tube Amplifier Design have considerable collector value.) Rozenblitt's association with the Transcendant OTL or your assessment of his ability to understand "critical damping" have nothing to do with anything contained in the book. I feel a bit silly defending Rozenblitt's book, but I also feel a bit unfairly attacked for having recommended it.
