Complete manual with test data hickok 539C tube tester
This is a very nice comb-bound reprint of the Operators Manual including schematic for the Hickok 539C Tube Tester. I have added the hard-to-find calibration instructions.
Included is all of the tube testing data I have collected for the 539B and 539C. The 539 and 539A use different settings. The first section is the roll chart in book form. It covers from 0A2 to 8628 in 23 pages. There is no date or code number. Second is a two page supplement #3200-330S which covers 3GY5 through 8950. The third section is "Obsolete Tube Types" #3200-163, dated 1968. It starts with 0A4 and covers all of those 4 and 5 pin antique radio tubes like 19, 22, 26, 27, 30, 31, 32, 33 etc. The last number on the list is Loktal #XXL. The next section is "Foreign Tube Types" #3200-254, no date. It runs from 1AJ4 through ZD152.
