3CX10,000A3/8159
The 3CX10,000A3 is a forced air cooled, ceramic/
metal, medium-mu power triode designed primar-
ily for use in industrial radio-frequency heating
services. Input of 32 kW is permissible up to 140
MHz. Plentiful reserve emission is available from
its 743 watt filament. The grid structure is rated
at 250 watts, making this tube an excellent choice
for industrial service.
