This listing is for a Reproduction McCandless/DeForest Spherical Audion Triode Vacuum Tube. This tube is a reproduction. The original design used a Tantalum filament, but was physically unstable. McCandless changed the filament to Tungsten, but Tungsten had lower electron yield compared with Tantalum. Hudson proposed that the filament should be made from Tungsten wrapped with Tantalum to get the best of both metals. DeForest produced tubes of that design primarily for military use. McCandles found the two part filament expensive and cumbersome to make so he introduced the Tungsten filament coated with an organic binder which bound Tantalum to the Tungsten filament.This particular tube is an example of this coated filament tube. This tube is in excellent cosmetic condition. My previous example of this tube showed gM~25 at 2.5 volts Filament, 64 volts Plate. I cannot give a comparison with the marking because I do not know what grid bias was used for the test. I used -6 volts, same as the specification for an 01A. I got gM~40. This comes with a proper screw base socket. This is 100% guaranteed to be as described. I am happy to answer your questions to the best of my ability.

From previous tests I have made of other similar tubes, I tested this tube at 2.5 volts Filament, 64 volts Plate. I cannot give a comparison with any specification but I got gM~20.

This listing is for a Reproduction Globe Type Inverted Elements Audion Type Triode Vacuum Tube on Wood Base. When I say Inverted Elements, I mean that the Plate is a flat piece of metal going down the middle of the tube, the Grid is nicely made coil of wire, and the filament is a pair of wires going up each side of the assembly. I have never seen a tube fabricated like this before. It is mounted on a wood base, typical of the way in which these types of tubes were used. This tube is post-1920 in build since it has a getter. This tube is in excellent cosmetic condition. I set up a test leads on my tube tester and did get significant mutual conductance (~35, which is in the range written on the tube envelope). I cannot give a comparison to any specification because I do not know what grid bias was used for the the number given on the glass. I used 5 volts on the filament, -8 volts grid and +150 volts plate, same as the builder of the tube marked, other than the grid bias, which I guessed at. This tube has seen service as evidenced by the colorations on the Grid electrode. This is 100% guaranteed to be as described. I am happy to answer your questions to the best of my ability.

This listing is for a Reproduction DeForest Spherical Audion Triode Vacuum Tube - Interdigitated Grid. My now-confirmed expert on these types of tubes does assert that this is a reproduction tube, though the purpose of the interdigitated grids remains unknown. The term Interdigitated Grids means that this tube has two independent grids. However, they are coplanar, meaning that both are control grids and they are fabricated in a pattern known as interdigitated. I have no idea why the builder of this tube did this but it got the most unusual tube I have seen by far. Perhaps it served a function as a summing junction that would add the signals from each grid to the output current. This tube is post-1920 in build since it has a getter. This tube is in excellent cosmetic condition. I set up a test socket on my tube tester and did get significant mutual conductance. I cannot give a comparison to any specification because I do not know what grid bias was used for the the specification. I used -6 volts grid and 65 volts plate, same as the specification for an 01A. This tube has seen service as evidenced by the colorations on the plate electrode. This is 100% guaranteed to be as described. I am happy to answer your questions to the best of my ability.
