Default Jackson 648 test for 6973

I have a Jackson 648 tube tester. I am rebuilding my jukebox amp this weekend and I want to test my power new power tubes before I plug them in. Does anyone have the test info for the 6973 tubes.

Does it list 6CM6 or 6CZ5? Those are close. 12AB5 is the same pinout as well, but with 12V heater.
