Amperex was a long-established manufacturer of transmitting tubes when they were acquired by the Dutch firm, Philips in 1955. Philips used the Amperex name to distribute their new line of Dutch-made miniature tubes, such as 12AX7, 12AU7, 12AT7 to feed the American Market. Classic hi-fi brands such as Marantz, Fisher, and H. H. Scott, Inc., used Amperex valves. Amperex also produced the 6DJ8, 6922 and 7308 frame grid tubes. The 6DJ8/ECC88 was developed by Amperex in 1958 and originally developed for video and radar use, the 6DJ8 also excelled in audio amplifiers. Amperex valves were original equipment parts in many models of Tektronix and Hewlett-Packard test equipment. Although Amperex especially the original "Bugle Boy" series) are now very sought after for their sound quality.
This American made 5U4GB Amperex is of the highest quality rectifiers that we have had in stock. Amperex was the North American brand owned by the famous Philips group.

These 5U4GB have the brown micanol base, micanol was a special heat resistant base that was specified for military use. The valve has a triple getter with a double getter at the top and a single getter at the side, unlike the standard items which have a single getter at the top.

The Amperex 5U4GB has thick mica supports at the top and bottom of the valve with the anode plates black grey coating. This valve also has a thick glass envelope which makes it very resistant to rattle and vibration.

These have proved to be long lasting in demanding applications such as Mesa Boogie Single, Dual and Triple rectifier's amplifiers and work very well in all Fender amplifiers such as the reissue bassman 1959.

American made 5U4GB are getting very hard to find and so we limited stock of this item.
