notes: label: Description (Brief)
content: Westinghouse WD-11 triode, brass base shell with 4-pins (long), T-shaped tipped envelope, lime getter. Donor card reads: "Triode made by the Westinghouse Company for use in their Aeriola dry-cell operated radio receivers. Carried in the first tube catalog of the Radio Corporation of America dated 1 June 1922. The WD-11 was mounted on a special base to fit the Aeriola receiver sockets. Filament: 1.5 volts at .25 amperes. Generally a very unsatisfactory tube because of the fluctuation of the battery voltage. These tube lasted only a few hours in operation, and in 1922 cost $8.00 each. Superceded in 1923 by the UV-199 three volt battery operated tube."
