content: A glass tube with large copper heat sink on the bottom, and a metal top cap with 8" braided copper leads. Stamped: "Rectron / UV-214 / [RCA logo]". Donor’s card reads: “Half-wave vacuum rectifier made by the General Electric Company for the Radio Corporation of America in 1923. For use in plate supply of large broadcasting transmitters. Was the first water cooled rectifier made, requiring 3 gallons per minute. RCA letter dated 13 January 1960 says that the UV-214 was discontinued altogether about 1945. Used with UV-207 and UV-852 triodes to supply plate power. The U-214 was identical to the type 207, except the omission of the grid. Tungsten filament: 22 volts at 52 amperes. Peak inverse plate voltage 50,000, peak plate current 7.5 amperes.”
