Hello All, I'm trying to find tube tester settings for some older tubes. I plan to start working on a Philco model 60 and my current charts no longer have settings for these old tubes, namely 6A7, 78, 75, 42, and 80. Any help would be appreciated.
Thanks,
Bob

Terry,
Thanks!! This is the most inclusive list I've seen. I must have spent 4-5 hours on google today.
Regards,
Bob
