Hickok 800 Tube Testing Tubes from 1965 Ampeg Gemini I

Testing the tubes from the 1965 Ampeg Gemini I G-12 I'm working on using my recently calibrated Hickok 800 Mutual Conductance tester. There are mixed feelings about using tube testers to check tubes. I mainly use it to check for tubes to see if they are completely shot before I use them - ones that I do not want to put into an amp because of shorts, or dead filaments - catastrophically bad in other words. As a wise man once posted, there probably have been a lot of good tubes tossed because of tube testers, and I can't argue with that. And I think it's fun!
