Since vacuum tubes were made 30 ? 70 years ago New Old Stock or Used may have cosmetic evidence of age.  This includes poor print, oxidized pins, faint discoloration, or poorly box
Two testers are never the same.  So this shows what I get, and what you get may be slightly different.
If I state any values they are for a guide only.
No guarantee is made that any tube will test to a specific value in the buyer's tube tester, most all tubes are tested on at least two tube testers
This because of the variation in line voltage, different bias, and circuits.
