Product Description

The 3CX4500F3 is a forced air cooled, ceramic—metal medium-mu amplifier factor power triode containing a thoriated tungsten carbide cathode designed for mainly used in amplifier, oscillator and modulator. High output power can be obtained as operatng in medium-mu voltage.The tube connects with service by theflexible lead cathode and the firm flange on the grid in indultrial application.
