This listing is for a pair of GE NOS NIB 6SN7 GTB Chrome top, Black plate, Top Halo Getter Vacuum Tubes. Both tubes have the same markings. Tested on my HICKOK Model 6000 Dynamic Mutual Conductance Tube Tester. They both tested 2800 Micromhos better than new on Plate No. 1 and Plate No. 2. Packed with care and shipped immediately.
This NOS not only had good appearance, it had top performance with a gain 40 and 2000 umhos transconductance. The GE tube appeared in a good display with an EICO tube tester in the background assuring experienced selling. An excellent matched pair of vintage electron valves.
