content: A double-ended, side-tipped glass envelope with spiral collector grid, flat plate collector, and tungsten emitter in a circle near the grid. Leads emerge from both ends and from the tip. No extant markings. Tube envelope broken at one end. Described as a De Forest tubular "Audion" radio tube but this is not a commercial DeForest Audion tube. It appears to be something experimental.
