The 3CW7000H3/Y-842A is a water cooled, ceramic/metal, medium-mu power triode designed primarily for use in industrial radio frequency heating services. Its water cooled anode is conservatively rated at 7 kW of plate dissipation with low water flow and pressure drop. The tube is a version of the air cooled 3CX4500F3 and is recommended for industrial applications where reserve anode dissipation is required. Input of 25 kW is permissible up to 75 MHz. Plentiful reserve emission is available from its 546 watt filament. The grid structure is rated at 300 watts, making this tube an excellent choice for industrial service.
