you see, this is why I advised you to get a REAL tube tester, rather than
that little toy tester you are using.

if the tube is boxed, and the flashing is 100%, seller reputable, then it is

about 99% likely


99% of NOS tubes I buy on ebay are truly NOS!


get a real tube tester, and get it calibrated
