Amperex Electronic Corporation was a manufacturer of valves and semiconductors based in Brooklyn, New York.
Originally located at 79 Washington Street in Brooklyn, New York, Amperex was a long-established manufacturer of transmitting valves when they were acquired by the Dutch firm, Philips, (known more widely as Norelco in the US), around 1955. <=text=>Philips continued to improve and enlarge the tube plant in New York, but also used the Amperex name to distribute their new line of Dutch-made miniature tubes, (12AX7, 12AU7, 12AT7) to feed the booming U.S. hi-fi market. Classic hi-fi brands such as Marantz, Fisher, and H H Scott, Inc., used these valves.
Amperex also produced the 6DJ8, 6922 and 7308 frame grid valves. Developed by them in 1958, when transistors were beginning to supplant valves, and originally developed for video and radar use, the 6DJ8 also excelled in audio amplifiers needing its high transconductance, and it still has a niche market among audiophiles.
