3CX5000H3
The 3CX5000H3 is a forced air cooled, ceramic/
metal, medium-mu power triode designed primar-
ily for use in industrial radio frequency heating
services. Input of 23.6 kW is permissible up to 90
MHz. Plentiful reserve emission is available from
its 560 watt filament. The grid structure is rated
at 150 watts, making this tube an excellent choice
for industrial service.
