The 3CW30,000H7 is a high-mu power triode designed for use as a zero bias Class B RF amplifier, Class C power amplifier or oscillator, or for voltage regulator service. Input of 48 kW is permissible up to 110 MHz. Plentiful reserve emission is available from its one kilowatt filament. Class B operation with zero grid bias offers circuit simplification by eliminating the bias supply. Class of Operation Characteristics Plate Dissipation (Max.) Screen Dissipation (Max.)
