The TS6 is an UHF pulse power triode used in WWII for German radar. The filament used eight strands of bright thoriated tungsten wire and ran at 31 Amps and 2 Volts. This gave the electron density required for pulse operation. The TS6 was a specially rugged device that was designed to withstand the vibrations aboard a warship firing heavy naval guns.
GEMA (Gesellschaft fur elektroakustische und mechanische Apparate mbH), founded in 1934, made the wartime German radars. The Freya (land based) and Seetakt (Marine) both operated at 368 MHz 80 cm. Initially a pair of TS1 triodes operated in push-pull powered the radars. The TS1's were suseptable to heavy vibrations and the firing of big guns on a ship could disable its own radar. The TS1 gave a peak pulse power of 1 kW and a repetition rate of 1,000 pps. Later versions used a pair of TS6 triodes in push-pull delivering a maximum peak pulse power of 8 kW. The TS1 & TS1A were like the American 316A doorknob valve in shape and design. The TS6 had a maximum anode dissipation of 150 W.
The base showing the six pins. The filament connects to the outer pins. The lower pair of pins are the anode and the top pair of pins is connected to the grid.
The inner electrode structure. The eight strand filament is tensioned by the spring on the left. The grid is formed from a series of hair-pins connected to substantial supports. The filament runs between the wires of the grid and the valve has an anode on either side.
The balloon envelope is 100 mm in diameter, and excluding the base pins is 130 mm tall.
