content: Telefunken RE-16-C-11 triode, 4-pin base with T-shaped glass envelope, red stain inside top. Markings on envelope. Donor card reads: "Triode made by Telefunken for the German army in World War 1. An excellent detector, mounted on the German base of that period. A "hard" tube (high vacuum). Filament: 4 volts at .55 ampere. 65 volts on the plate. Used primarily as a detector for continuous wave signals (oscillating). Telefunken produced these tubes in 1918 at the rate of 1000 per day. Copper anode and grid indicate that this tube was made in 1918 after a shortage of nickel developed in Germany. Electrically similar to French "Fotos" type tubes.
