Penta maintains an aggressive program of product development and upholding tradition. We are positioned as the American manufacturer and distributor of electron and vacuum tube amp technology.

In addition of staying at the forefront of cutting-edge technology, Penta Laboratories maintains an extensive inventory of replacement vacuum tubes for equipment that dates back 75 years or more. Penta’s commitment to excellence begins with evaluation of design, in-house testing, overseeing the manufacturing process and is followed all the way through the distribution of the product. Penta’s stringent packaging standards ensure ample protection of each tube, and the our ability to respond quickly to orders ensures the highest possible degree of customer service.

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.
