Wanted: updated chart for Jackson Tube Tester

[Lee]

Anybody have an updated tube chart for a Jackson 648?
My tube checker and chart is from 1942 and only has
one tube begining with 6S and that’s 6SN7 all the other
ie “all american 5” tubes 6SQ7 6SK7 and the 12SK7 etc etc.
do not show up on the chart.
I think there are updated tube charts out there that have been printed
all the way up until 1972. I would be happy to find any edition just a little
newer than 1942.
Please post here or email reply directly to atlelee at gmail dot com.
Thank you.

Thank you to Pat as he emailed the charts to me.
I now have tube settings for tubes up to 1962! If anyone else needs these files I will be happy to pass these along by email to you. The files are big one is 8 Megs and the other is 13.8 Megabytes.
