Armstrong J5

A little tube-shaped Armstrong J5 "aerial eliminating tube". "Stops aerial noises". From Armstrong Radio Apparatus, Westmont, NJ. The only internet reference is one in the Drexel U/Atwater Kent Museum collection. Seems to be able to filter noise and maybe as an antenna amp. Time to test it on my Radiola 60.
