In Reply to: By writing on the box flaps, have I compromised the value? posted by Sigmund on November 14, 2016 at 14:23:03:
I tested hundreds of small signal tubes around the turn of the century and applied the test results via office supply sticky labels.
They were stored in a wood cabinet with shoe box sized drawers (most tubes being without individual boxes) and when I checked them 6-7 years later most all of the stickers had detached from the tubes.
By this time I had gifted and/or sold my good/calibrated testers (2 TV-7's and a 539C) as I figured that I would not require them anymore (no longer buying small signal tubes).
The last TV-7 I kept only reliably tests DH/SET's (same results with 2A3/300B as the good testers), but it has a tendency to oscillate with small signal triodes (which maxes out the dial) and it does not perform properly with el84/el34 et cetera.
The only plus is that I did not keep any small signal triodes that didn't meet new spec, but now I am without a tester to re-match them.
Should have purchased bulk boxes and labeled the individual boxes in hindsight.
