I have a Simpson model 305 tube tester with an operatorâs manual dated 1954 which contains tube chart data. I am wondering if there are any newer tube chart data that can be used to test 1965 era tubes, such as, 6EU7 and 6GW8?

I've never seen any. Coletronics produced data books for several popular testers after their manufacturers gave up on them, but I don't know about Simpson.

Why not just go to Simpson's website, Tech Support page and make a request there.
They still have Model 260 multimeter info online, maybe they can help you.

Chuck,
It was a good idea but Simpson said they don't support items that are more than 7 years obsolete.
