The 3CX5000A3 is a medium-mu power triode designed primarily for use as a power oscillator in industrial heating applications. It is also recommended for use as a grounded grid FM amplifier, as a conventional plate modulator, or as a linear amplifier. Plentiful reserve emission is available from the 560- watt filament. The grid structure is rated at 100 watts making this tube an excellent choice for severe application. Characteristics Plate Dissipation (Max.) Screen Dissipation (Max.) Grid Dissipation (Max.)
