This offering is for one NOS Sylvania smoked glass 6V6GT tube, made in 1965 for use by the FAA. Tested good for all parameters, and 4000/4100 on the Mhos. scale using Hickok 6000 tester.
Also offered is an identical tube that tested somewhat questionable on my tester, specifically the fourth neon lamp was out, indicating the possibility of a short, or with a good shaking it might remedy itself.
So you are getting at least one good, strong NOS 6V6 tube and a naughty one as well.
