Founded in 1951, Penta Laboratories has grown into one of the world’s leading manufacturers of vacuum tubes and electron tubes for applications ranging from high-end audio to broadcast, medical, military, science and more. The company—perhaps best known for developing the beam-powered Pentode vacuum tube—balances state-of-the-art manufacturing operations and quality control processes with a strong commitment to excellence in customer service.
Penta Laboratories’ success is predicated on an aggressive product development program that continues to churn out cutting-edge products backed by strict standards in design evaluation, testing, production and delivery. In addition to staying at the forefront of new technologies, the company maintains an extensive inventory of replacement radio tubes, triodes, diodes, tetrodes, and more parts for equipment dating back more than 75 years.
Penta Labs RF Vacuum Tubes
Penta Laboratories was founded in 1951 and is a world-class manufacturer and distributor of a wide range of vacuum tubes for a variety of industries. Penta's commitment to excellence begins with design and follows each product all the way through distribution. Penta Labs matched vacuum tubes go through rigorous test procedures to enhance performance during their operation. Each Penta Labs vacuum tube is burned in for a minimum of 48 hours dissipating full power with filament, plate and screen voltages that are normally used in amplifier applications. All of this ensures that the various electrical parameters have stabilized and the matching of each vacuum tube will not drift during its lifetime. Penta Labs power tubes are matched within a 5% variation on all parameters. This is a process of eliminating tubes that test with bad values, rejecting those outside limits of design. Each passing vacuum tube is then tested on a fleet of WT-100A original RCA production testers for plate current, screen current and transconductance (gm). We also check for grid current and leakage between elements. When you receive single and matched vacuum tubes from Penta Labs, you can rest assured that you are receiving a product that has been thoroughly tested and will perform at levels unsurpassed in the industry. DX Engineering offers a selection of Penta Labs single and matched sets of RF vacuum tubes and ceramic vacuum tubes for your electronics project or repair. Order yours today!
