I just acquired a 539B and I am trying to find the latest tube data available for this tester. I am finding bits and pieces online from various years which makes it difficult to figure out what was added or deleted from the data, as time went on.

For my Jackson 648A I bought the definitive Jackson manual with tube data from Vacuum Tubes Inc which is a real convenience. Is there something similar for the 539B? Is there a compilation of all the data for this tester that any of you have found useful?

Probably best to look at the Hickok 539C roll charts/data. I have seen complete sets (manual/data) for 539B/C tube tester information for sale online, but the quality usually isn't very good. The last 539C roll chart I have is 1963 (believe final versions went into late 60s), I am slowly compiling roll chart data from several sources for this tester and am putting it in an excel spreadsheet. Hope to post in about a month when I find some time to complete. There are a few nice mods for the 539 that I have already posted, depends on the type of tube you are testing. The 539 is a good tube tester, but limited in it's plate voltage.

Thank you for the links, I revisited them and did download the WE tube data.
I am not sure what the eBay seller would have that wasn't in the links you pointed me to.

Just checked the roll chart in my 539B and it is dated Fall 1971, so I probably have the latest one?

Last roll chart I know of for 539B & 539C is dated 1974....
