Because of its ability to provide superior quality power tubes at competitive prices, while maintaining the highest standards of service, Penta Laboratories has become a valued resource for an ever-increasing number of independent and public radio and TV stations and operators. Moreover, each vacuum tube is extensively tested prior to shipment to ensure that optimum levels of on-air performance will be maintained. Penta power grid tubes and cavities are available for all broadcasting requirements, as are klystrons and millimeter-wave power amplifiers.

This is only a partial list of the products that Penta Laboratories typically carries, please contact us directly to inquire about other tube types.

  • 3-500ZG

    The Penta Laboratories 3-500ZG is a high-mu power triode with a maximum plate dissipation rating of 500 watts. Cooling is by radiation and forced air through the base, along the envelope, and over the plate seal and radiator-type plate connector. It is intended for use as a zero-bias Class AB2 amplifier in radio-frequency or audio frequency applications. By eliminating the bias supply, zero grid bias operation greatly simplifies circuitry design. When operated in a cathode-driven circuit, a power gain of as much twenty times is achievable.

  • 3-500ZG Matched Pair

    The Penta Laboratories 3-500ZG is a high-mu power triode with a maximum plate dissipation rating of 500 watts. Cooling is by radiation and forced air through the base, along the envelope, and over the plate seal and radiator-type plate connector. It is intended for use as a zero-bias Class AB2 amplifier in radio-frequency or audio frequency applications.

  • 3CX800A7

    The Penta Laboratories 3CX800A7 is a compact power triode intended for use as a cathode-driven Class AB2 or Class B amplifier 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 is useful to 450 MHz. The anode is forced-air cooled for 800 watts of dissipation.
