The 4CX1500B/8660 tube is radial beam tetrode which is rated for 1500 watts maximum plate dissipation. Construction is metal/ceramic, and cooling is via forced-air. The high current, low voltage and low distortion design of the 4CX1500B/8660 makes it ideally suited for use in audio amplifier or Class AB1 RF linear amplifier applications. In addition, the 4CX1500B/8660 exhibits exceptionally low intermodulation distortion and low grid interception for a tube of its power output.

4CX20000A/8990 is a high-performance ceramic/metal power tetrode designed for audio and radio frequency applications. It is particularly well-suited for use in VHF FM broadcast transmitters in the Band II 88-108 MHz frequency range.

4CX20,000D/9015 is a ceramic/-
metal VHF power tetrode intended for use as
a RF amplifier up to 110 MHz. It is particular –
ly recommended for use in the 88-108 MHz
FM band. It features an electromechanical
structure which provides high RF operating
efficiency and low RF losses. The 4CX-
20,000D has a gain of up to 20 dB in FM
broad-cast service. The anode is rated for 20
kilowatts of dissipation with forced-air cool-
ing and incorporates a highly efficient cooler
of new design, which significantly reduces air
pressure and flow requirements and produc-
es low acoustical noise.
