Super rare near impossible to find NOS tubes of this type. Beautiful vintage tube, Coke bottle style glass, black plate. A superior tube that can be used as an upgrade, replacement of 6L6GC types. The transconductance measured 7, 250 m mhos with a plate current of 72 ma, this is higher than any of the NOS 6L6GC tube types I have tested. No shorts or gas, a perfect NOS tube with perfect test results. There is a special section for Western Electric tube types in my Hickok test char...t book and instead of listing minimum values like for other tube types an average value is listed for NOS tubes and the average value for this tube is listed as 6, 000 m mhos.
