Ultimate manual: hickok 800A tube tester
This is a very nice comb-bound reprint of the instruction manual for the Hickok 800A tube tester AND MUCH MORE. I got the original from a retired Army Signal Corps officer. He spent the last 40 years compiling this information. The first section (18 pages) is the regular operator's manual including several pages of data for testing ballast tubes, calibration instructions (including several pages of extra info on maintaining your tester), and a big 11x17" schematic. The next section (23 pages) is a copy of the last roll chart for the 800A released by Hickok just before they went out of the tube tester business. I don't have the code number, but the old man stamped it when he received it: November 7, 1989. Next is a 3 page supplement covering new tubes not in the chart, mostly compactrons. It has the code number 3200-325S. Then there are two pages of very hard-to-find testing data for Western Electric tubes. The next section (24 pages) is the "Obsolete Tube" listings, code number 3200-159, which are the older tubes left off the latest roll chart. The next section (26 pages) is the foreign tube data, code number 3200-253. Here he has written in the American and other foreign numbers for many of the tubes. There are often several European numbers for the same tube. Next is a one page American to Foreign chart of numbers not in the Hickok listings. Next is an amazing 4 page section where he actually created correct test data for tubes that Hickok never provided data for. Next is a 2 page section of test data for electron ray (Eye) tubes that shows how to give them a more complete test than the regular chart does. The next section (9 pages) is a very good Foreign to American number chart. The next section (10 pages) crosses over those 4 digit military numbers to their regular equivalents and vice-versa. The last section (10 pages) is a collection of Foreign to American cross over charts. 127 pages in all. I've wanted a book like this for years. The covers are made of card stock and are protected with clear sheets.
