CPI 3CW30000H7

The 3CW30,000H7 is a high-mu power triode designed for use as a zero bias Class B RF amplifier,
Class C power amplifier or oscillator, or for voltage
regulator service. Input of 48 kW is permissible up
to 110 MHz. Plentiful reserve emission is available
from its one kilowatt filament. Class B operation
with zero grid bias offers circuit simplification by
eliminating the bias supply.
