The 3CX3000A7 are forced air cooled ceramic-metal power triode containing a thoriated tungsten carbide cathode of which the maximum plate dissipation up 4kW and are designed for used as RF power amplifier, oscillator, or modulator.
In order to simplify the installation of application at low-frequency, the base of the FU-3032F attaches a flexible of grid and cathode on .
