EMI engineers Cabot Bull and Sidney Rodda improved the Harries design with a pair of beam plates, connected to the cathode, which directed the electron streams into two narrow areas and also acted like a suppressor grid to redirect some secondary electrons back to the anode.
The beam tetrode design was also undertaken to avoid the patents which the giant Philips firm held on power pentodes in Europe. Because this overall design eliminated the "tetrode kink" negative resistance in the lower parts of the tetrode's voltage-current characteristic curves, which sometimes caused tetrode amplifiers to become unstable, MOV Marconi-Osram Valve , a subsidiary of EMI jointly owned with General Electric Company Ltd marketed this tube family under the sobriquet "KT", meaning "kinkless tetrode".
Because MOV's engineers did not feel the kinkless tetrode could be successfully mass-produced, they licensed the design to RCA.

All their tube articles are rife with errors! Many instances of misidentified tubes, misinformation about production history, undefined subjective terms rampantly bandied about, gratuitous omissions Nothing too consequential, ultimately, but ubiquitous enough to be really annoying.
