Its industrial equivalent is the 6267. NOS is subject to interpretation and there is no specific definition for it either. There are suggestions and opinions. Tube testers do not test for these problems in the manner in which you think, except to the extent that a tube tester with sensitive leakage detection will find far more “noisy” tubes than a tube tester with only “fair” leakage sensitivity, to the extent that the noise is due to this problem.
