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".
