3CX800A7 Matched Pair
The Penta Laboratories 3CX800A7 tubes for sale are compact power triodes intended for use as cathode-driven Class AB2 or Class B amplifiers in rf applications, including the VHF band. As a linear amplifier, high power gain may be obtained without sacrifice of low intermodulation distortion characteristics. Low grid interception and high amplification factor combine to make the 3CX800A7 drive power low for a tube of this power capacity. A single 3CX800A7 will deliver 750 watts PEP and 750 watts key-down CW output power to 350 MHz. The 3CX800A7 tubes for sale are useful to 450 MHz. The anode is forced-air cooled for 800 watts of dissipation.

4CX1500B
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.

4CX20000D
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.$3,994.99
