DESCRIPTION:
Type:
Condition: Tested Low but good Back up tube
I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I don't guarantee or imply anything else.
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. Please expect the tube to have a small
amount of used
Since
vacuum tubes were made 30 – 70 years ago New Old Stock or Used may have cosmetic
evidence of age. This includes poor print, oxidized pins, faint
discoloration, or poorly box
Some boxes may be to brittle to salvage or not original

I own 5 Hickok tester and
about 6 other brand and all display a slightly differing value.
if I test the same
tube, as two testers are never the same. So this shows what I get,
and what you get may be slightly different.
If I state any values they
are for a guide only.
All tubes have passed the
Gas and short tests.
Rectifiers and Diode tubes
do not have Transconductance values.
IMPORTANT:
All My electronics are stamp with
a label or with in an invisible security pen identifier to ensure
that, in the event of a return, I get it back with all the pieces in side us
originally sold. The stamp is very similar to the chalky paint that tube
manufacturers used but it can only be seen with a UV light and as such, it is
removable if rubbed with sufficient force. Please be careful not to rub
the stamp off until meets your satisfaction! Under no circumstances will I
accept return item for return that are missing this stamp or the
label is broken.
