3CX20,000H3
The 3CX20,000H3 is a forced air cooled, ceramic/
metal, medium-mu power triode designed primar-
ily for use in industrial radio frequency heating
services. Input of 84 kW is permissible up to 90
MHz. Plentiful reserve emission is available from
its 1600 watt filament. The grid structure is rated
at 800 watts, making this tube an excellent choice
for industrial service.
