The Pickering XV-15 400E is an electrical vacuum tube used primarily in high-power RF amplification applications. It is a tetrode tube, which means it has four active electrodes: a cathode, grid, screen grid, and plate. The "XV-15" designation refers to the tube's basic technical specifications, and the "400E" adds that it is a specific model with a plate dissipation rating of 400 watts. The high power handling capacity of this tube makes it ideal for use in broadcast transmitters, military communications systems, and other high-power RF applications.
