They were tested on my recently calibrated Hickok TV-7 tube tester with scores of 75 and 76. A minimum value score on my tester for these tubes would be 47 so these tubes test 100%. They do not have original boxes, but they test 100%. They have tight bases and no loose particles inside. We trust priority a bit more, but will adjust according to the needs of our customers.
