Here is 1-NOS-NIB WESTINGHOUSE 50Y7gt BLK Plt. bottom getter. I always let my tubes warm 20 min. to 1/2 hour before test .This tst @ 8000 NOS for this tube. Tested on a Accurate 257 tester Warmed for a 1/2 hr.Before tested. 1000=bad, 2000=min,4000=? And really anything above 6000 is NOS range. FOR SOME TUBES. It's very RARE to find any NOS tube that's Over 9000..
