Tested at 47

on a calibrated TV-7D/U tube tester on which 15 is the minimum

***On some tubes the minimum being 65% of the typical new score is not a workable formula on the TV7-D/U. So a % score is not meaningful and only an actual meter reading is given. These are

Most rectifiers & diodes - 6BL8 - 6BM8 - 6DA6/EF89 - 6GM8 - 6GW8 - 12BH7 - 22KV6 - 76 - 80 - 5842

Test results may differ between various testers for many reasons such as technical design, aging components, etc. So while test results are a good indication of quality there can be some difference between the many differently designed & maintained testers.
