PENTA LABORATORIES

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 American vacuum tube and amp manufacturing 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 American manufacturer and distributor of a wide range of electron tubes and vacuum tube amps.

Our product line covers broadcast, industrial, research, military, medical, scientific, and high-end audio applications.

We have over 8,000 stocking part numbers and an inventory far in excess of a million vacuum tubes. 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.

The American manufacturing company maintains an aggressive program of product development and is positioned at the cutting edge of vacuum tube and tube amp technology. By the same token, Penta Laboratories maintains an extensive inventory of replacement vacuum tubes for equipment that dates back 75 years or more.
