(1) Tested Valvo EBC41 Tube (6CV7 equivalent).
Please note this is a "Rimlock" based tube (beaded side key on glass with 8 continuous pins).

The wording is mostly worn away from the glass but still recognizable as being Valvo branded.

Tested on a calibrated Hickok TV-10 military tube tester with no shorts and no leaks with the following results:

Gm Test = 1250 micromhos
Minimum pass/good = 800
Each diode section tests at 1500 and 1550 where 800 is minimum pass/good.
