Glass-metal 'micropup' transmitting triode; unipotential oxide-coated cathode. Brass finned plate radiator. Two tubes gave 100 to 150 kW pulses at 200MHz. Usable well beyond 600 MHz.

Canadian equivalent of CV92. According to the labels on the tube in the pictures and on the box of the known samples, tubes were made by Canadian Rogers for REL. Labels also report direct equivalences to 4C27 and to 10E/CV92.
