Rare Amperex Orange Globe NIB NOS 6SN7 GTB Tube, Copper Grid Posts, Chrome Side Getter, Clear Top. The tube is New In Box and has never
been used. Legendary Amperex U.S. Globle 6SN7GTB tubes are great sounding tubes.
Date Codes:
68-26 (so tube was manufactured in the 26th week of 1968).
Tube is tested on our military TV-7D/U mutual conductance (Gm) tube tester,
which was recently restored and calibrated by Dan Nelson - the King of
TV-7 series tube tester restoration and calibration. TV-7D/U test
results (also refer to photos for measurements):
* Minimum good for 6SN7 tubes on TV-7D/U is 50 (65% of NOS), so
Below 50 =
Low testing tubes 50 - 77 =
Good tubes 77 and above =
NOS tubesSo
the tube is very strong, way above the NOS level. Also, both sections are Platinum Matched, tightly within 5% of mutual conductance.
No shorts, no leakage, no gas, no loose base.
The tube also has been sound-tested on our modded Dark Voice 336SE
headphone amplifier. It sounds fantastic, no microphonics, no hissing
/ crackling / or other noises. Background is dead quiet.
Tube will come with the original Amperex box.
