EICO 667 Tube tester data sheet inaccuracies

[bowtieman427]

Hi all, Friend loaned me a EICO 667 tube tester he built. Read somewhere that the tude test data sheets are inaccurate for some tubes. Can anyone direct me where to get the correct information. I am currently testing 12AX7, 7868, and 7591. Tubes to be tested primarily audio vintage tube equipment and organs.
Thanks in advance
Jim

The Test Equipment Discussions Forum at AntiqueRadios.com contains more information from experts than anyplace else I've ever found.

Do a search inside Test Equipment for "Eico and 667" (no quotes). I found 91 threads.

[Edit]: There are many different versions of roll charts for this tester. Some have mistakes, some newer versions corrected those mistakes, and contained newer mistakes. It can be a real challenge sometimes!
