Penta Laboratories has been the worldwide leader in vacuum tubes, electron tubes and capacitors since 1951. 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. Penta is uniquely positioned as a company with the necessary resources to handle large volumes, yet is small enough to care about every order. Penta's customers are, after all, the most important element in the equation. It is customer satisfaction that Penta Laboratories values as the foundation of its entire business.
