The 3CX2500F3 is a forced air cooled, ceramic/
metal, medium-mu power triode designed primar-
ily for use in industrial radio frequency heating
services. Input of 14 kW is permissible up to 75
MHz. Plentiful reserve emission is available from
its 386 watt filament. The grid structure is rated at
150 watts, making this tube an excellent choice for
industrial service.
