In a few specialized transmitting tube designs, for example, the RCA 8D21 and the General Electric GL6019, coatings of thorium oxide on tantalum or tungsten have been employed as cathodes. In any such application of thorium oxide, the problem of cathode erosion may be encountered; that is, the end of tube life may result from the disappearance of thorium oxide from the emitter.

Dual tetrode construction did away with the need for neutralization of these stages, assuring better picture quality and less likelihood of adjacent channel interference.
