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.

Life Calculation: 90+% (where 65% = fail)

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)

4. Test for proper gain of the tube (perhaps the single most important test of a preamp tube

6. Repeat all tests for accuracy on another tester
