Description

The EIMAC 3CV30,000H3 is a vapor-cooled, ceramic-metal power triode designed primarily for use in industrial radio-frequency heating service. Its vapor- cooled anode is conservatively rated at 30 kilowatts of plate dissipation when mounted in an EIMAC BR-200 boiler. Full input of 60 kilowatts is permissible up to 100 megahertz. Large re- serve emission is available from its one kilowatt filament and the grid structure is rated at one ampere making this tube an excellent choice for severe applica- tions. It is also recommended as an audio amplifier, a conventional plate-modu- lated amplifier or as a linear amplifier in new equipment designs.
