Description
Pair (2)
General Electric
12AX7
Amplifier tubes.
Long Gray Plates.
TV-7 test strong.
Up for bids is a good testing pair (Gm) of General Electric 12AX7 amplifier tubes.
Some of the silk-screened labeling on these tubes has worn off.
Both tubes are nearly identical in appearance and construction with thick chrome top flashing and long gray ribbed/ladder style plates.
They were tested on my Dan Nelson calibrated TV-7/U tube tester for transconductance (Gm), gas, noise, and shorts using a digital meter for greater accuracy.
The TV-7/U minimum recommended value (65%) for each plate of the 12AX7 is 32 (Gm=800).
As pictured with TV-7/U test results & Gm:
TV-7/U               Gm
1.  47   42          1175  1025
2.  42   42          1025  1025
Both tubes match within 6.4%.
