Brand new, one year warranty against tube quality.
4CX20,000C is a high-performance ceramic-metal power tetrode mainly used for audio and radio frequency applications. It is particularly well-suited for use in VHF FM broadcast transmitters. It is also recommended for rf linear power amplifier service. The anode dissipation is 20KW with forced-air cooling.
It features a type of internal mechanical structure which results in high rf operating efficiency. Low rf losses in this structure permit operation at full ratings to 110 MHz.
Applications:
FM broadcast service,
Radio frequency linear power amplifier service,
VHF-TV linear amplifier service.
