Power - Triode (over 1000V 100W) ·Triode
Water-cooled high-power transmitting triode intended for RF service. Western Electric data show very high plate-voltage and dissipation capability, making it a specialized industrial transmitter tube rather than a conventional power-output triode.
The Western Electric 220C is a triode listed in the supplied catalog table. It is a water-cooled transmitting type intended for high-power RF service.
Medium 4-contact bayonet base
