Up for bids is a nice matched pair of JJ Electronics branded EL84 6BQ5 amplifier tubes.
These tubes are identical in construction with long gray plates and halo / "O" shaped top getters.
They were tested for transconductance (Gm), noise, gas, and shorts on my Dan Nelson calibrated TV-7/U tube tester using a digital meter that also measures plate current.
The TV-7/U minimum recommended value (65%) for the EL84 6BQ5 is 50 (Gm=2500).
As pictured with TV-7/U test results, Gm and plate current draw.
TV-7/U          Gm       Plate current
1.      82           4100      16 mA
2.      77           3850      16 mA
From a Gm perspective, both tubes match within 6.1%.
Plate current draws are a perfect match.
