My Books

Where Can I Buy Them?

You know who these people are! If it's printed on paper and bound between covers, Amazon.com has it, or can get it! Regrettably, Amazon has taken something of non-cooperative posture with regard to small publishers, but they can special order my books for you, and on occasion, you may find a used copy advertised by one of their e-shops.

The ARRL, founded in 1914 by Hiram Percy Maxim, is a huge organization dedicated to promoting amateur radio, protecting amateur radio spectrum space, lobbying for ham-friendly legislation and regulations, and encouraging radio experimentation. In addition, they sell and distribute a huge assortment of interesting books, CD-ROMS, videos, and other training/technical/reference materials. I am very pleased to announce that they now carry Instruments of Amplification as well.

Antique Electronic Supply

These people sell every conceivable part for antique radios and vintage tube-based equipment. Get their catalog. It's full of tubes, transformers, speakers, miscellaneous parts and hardware, kits, books, and more! AES presently stocks The Voice of the Crystal, but not Instruments of Amplification

Artisan Ideas (Featured Seller)

If you are a student (or master) of  hands-on, from-scratch, craftsman-oriented activities like knife-making, blacksmithing, gunsmithing, metalworking, carving, or pottery,  then you don't need an introduction to Artisan Ideas dot Com. Artisan has provided the craftsman community rare and interesting books and DVDs on these subjects for more than a decade. I am very pleased to announce that Artisan is now a distributor of my books as well.

For some time, my friends in the U.K. have lamented the difficulty in obtaining my books. I'm pleased to report that both Instruments of Amplification and The Voice of the Crystal are now available through special arrangement with Camden. These people carry an amazing variety of books dealing with such topics as steam and internal combustion engines, hot air engines, horology, trains, boats, planes, mining, alternative technologies, and last but not least, electricity and radio! Give them a shout and tell them I said hello!
