Amperex

Located at 79 Washington Street in Brooklyn, New York, Amperex was a long established manufacturer of transmitting tubes when they were acquired by the giant Dutch firm, Philips in 1955 or so. Philips continued to improve and enlarge the transmitting plant in New York, but also used the Amperex name to distribute their fine new line of Dutch made minis, (12AX7, 12AU7, 12AT7) to feed the booming U.S. Hi-Fi market. These sweet & airy, but still full and solid sounding tubes have been the favorite of music lovers for 45 years! Classic Hi-Fi brands such as Marantz, Fisher, Scott, etc... owe a large part of their great sound to these tubes.

Developed by Amperex in 1958 when transistors were already starting to take over the electronics industry & originally developed for video & radar use, the 6DJ8 has come into heavy use in audio over the last 15 years.
