Title: Radio Tubes Vade-Mecum P.H. Brans Post by: Todd, KA1KAQ on August 30, 2007, 11:13:34 AM Definitely a 'must have' if you use vacuum tubes. This Belgian publication has been around since the mid 40s. Earlier editions The book to have for cross referencing tubes of different countries, as well as finding heater voltages, base/pin information, and so on. Includes all known tubes at the time of publication, so the later additions are of course more complete. Later editions included the word 'Equivalent' in the title. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
