First made in March 1927, this tube type was sold to RCA to compete with the De Forest type H tube which was very popular with radio amateurs for use in the higher frequencies. Throated tungsten filament: 10 volts at 3.25 amperes. As a Class C radio frequency amplifier; 2000 volts at 60 milliamperes on the plate, 500 volt negative control grid bias, the tube will give 75 watts of radio frequency power.” See also: https://www.radiomuseum.org/tubes/tube_852.html.
