The 3CW40,000A5 is a medium-mu power triode designed primarily for use as an RF power amplifier. Input of 100 kW is permissible up to 90 MHz. Plentiful reserve emission is available from its 1500 watt filament. The grid structure is rated at 1000 watts dissipation. The electrical characteristics of the 3CW40,000A5 closely match those of the Siemens RS-2021W and it is therefore ideal as a retrofit. Class of Operation C Characteristics Plate Dissipation (Max.)
