Penta Laboratories was founded in 1951, and quickly achieved industry-wide recognition for the development of the beam-power Pentode vacuum tube. In 1973 the firm was acquired by The Raytheon Corporation, and has ultimately become a wholly owned subsidiary of Penta Financial, Inc.

Today, Penta Laboratories is a world class manufacturer and distributor of a wide range of electron tubes and vacuum tubes. Our product line covers broadcast, industrial, research, military, medical, scientific, and high-end audio applications. Our company is especially well experienced in the manufacturing of ceramic/metal vacuum tubes, triodes and tetrodes – a Penta specialty. Because of exceptionally high volumes in these key lines, Penta is uniquely positioned to support them with very competitive pricing.

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.
