Merrill Trainer, a young engineer in the This RCA 8D21 had a 5000 watt RF output to 213 MHz. These dual tetrode tubes were internally water cooled and served as amplifiers in early VHF transmitters . The final power stages of the aural and visual sections each used the RCA 8D21 dual tetrode operated as a push pull amplifier. Dual tetrode construction did away with the need for neutralization of these stages, assuring better picture quality and less likelihood of adjacent channel interference.
