Electronic Tubes

Electric Tubes — New & Used

Electric tubes (vacuum and electron tubes) are essential components in high-voltage, RF, and audio-frequency equipment, known for their ability to amplify signals, rectify current, and sustain performance under extreme electrical loads. Still relied upon in industrial controls, broadcast transmitters, and audio systems, these tubes deliver durability, stability, and consistent operation where solid-state components may fail.

At Surplus Select, we carry a curated selection of new and used OEM electric tubes from leading manufacturers such as RCA, GE, Eimac, Amperex, Raytheon, and Philips. Inventory updates daily, offering surplus pricing for vintage, industrial, and high-power tube applications.
