We provide the best value to our customers
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.
Penta manufactures a vast selection of power tubes used in industrial applications. Included are diverse manufacturing operations like welding, surface hardening, hot forming, sterilizing, soldering and heat sealing. Penta’s highly acclaimed RF generator vacuum tubes have proven to be exceptionally reliable in harsh industrial environments. In addition to the above applications, our tubes support instrumentation amplifiers, traveling wave devices, magnetrons, klystrons, gyrotrons and power generators.
