RCA 811A power triode vacuum tube. It is a transmitting tube often used in radio frequency (RF) amplifier applications.
The 811A was designed for demanding RF amplification needs and is known for its durability and reliable performance.
It was originally made by Radio Corporation of America (RCA) and was used by the U.S. government during World War II.
The tube is also suitable for use as an audio amplifier or oscillator.
The RCA-made 811A tubes are considered to be of higher quality than some newer versions, featuring plate fins that allow for more reserve during tuning in amplifiers.
