Please note: These tubes may be NOS or test NOS but will actually have a few hours of use from manufacturer or due from testing through time to time on them. A truly NOS tube will have excellent getter flashing condition, no dirt/grime, usually in the original box, and no filament deposits and has never been tested.

1. Complete visual
inspection
2. Allow 1 minute warm up time
3. Test for actual real-life mutual
conductance (life) of the tube (including any shorts,gas and leakage)
4. Test for proper gain of the tube
(perhaps the single most important test of a preamp tube
5. Test for noise -both in static and
dynamic situations
6. Repeat all tests for accuracy on other tester
If
some prove defective during testing, and we are unable to provide a substitute
acceptable to buyer, an immediate no hassle refund will be issued.
Please take
this consideration
If I state any values they are for a
guide only.
Two testers are never the same.
So this shows what I get, and what you get may be slightly different.
