This listing is for a Genuine DeForest Tubular Audion Audiotron Triode Vacuum Tube on DeForest Base. I have never seen a tube mounted this way. The tubular Audiotron is mounted in an insulating plaster-like material. There are two rectangular electrodes imbedded into this plaster, one grounded to the base, the others not connected to anything. I am told that this base was used by an experimenter to hold the tubular Audion. I added a photo of that tube base showing the uncommon shared labeling carrying both DeForest and Marconi markings along with a Fleming patent number 803684. Apparently the added base itself is a rare piece of history. Based on what people told me about my other Audion, presence of a getter pump, indicated that that tube was a a repoduction.This tube has no getter anywhere within or on the glass. It comes to you with the correct tube socket for easy display purposes. The socket itself is one I have never seen before. I have every reason to believe that this is original, made prior to 1920 and the introduction of getter pumps. This tube is in fair cosmetic condition, not too bad for 100+ years. The filament shows about 5 ohms. This is 100% guaranteed to be as described. I am happy to answer your questions to the best of my ability. PHOTO SHOWS ACTUAL ITEM FOR WHICH YOU ARE BIDDING!

I do listen to the experts! This listing is for a Genuine Cunningham Tubular Audion Triode Vacuum Tube on Wood Base. I looked as closely as I could under a microscope at all viewing angles and was not able to find any etchings identifying the manufacturer of this tube. In looking that closely, I observed an interesting detail about this tubes construction. The Copper-looking wire (Dumet - metal alloy with Copper cladding) that holds, and connects to the plate, is not spot welded like all other tubes of this type I have seen. The plate simply has a hole in it, the wires is twisted through the hole and mashed tight. Based on what people told me about my other Audion, presence of a getter pump, indicated that that tube was a a repoduction.This tube has no getter anywhere within or on the glass.It is mounted on a wooden base and the wafer where the plate and grid connections are terminated is Mica. I have every reason to believe that this is original, made prior to 1920 and the introduction of getter pumps. This tube is in good cosmetic condition. The filament is open. This is 100% guaranteed to be as described. I am happy to answer your questions to the best of my ability. PHOTO SHOWS ACTUAL ITEM FOR WHICH YOU ARE BIDDING!
