Amperex was originally an American brand with plants in Hicksville, Long Island, NY, Slattersville, RI and Cranston, RI. They produced receiving, transmitting and special purpose tubes. They developed a close relationship with North American Philips to market European tubes. As evidenced by the third box, NAP became the full owner sometime in the late 70's, apparently to get a foot in the door to US tube sales. Ultimately Philips bought Sylvania and the entire ECG line giving them ownership of two major US tube names, albiet the waning years of tubes. Amperex was a premium grade tube made in their own factories and then in Philips owned factories or purchased from other first line manufacturers. Their EIA/RETMA code was 111. Many of their tubes have the well-known GE frosted dots, indicating from whom they were purchased. The Amperex name is now owned by Richardson.
For the most part the writing on their tubes was orange, sometimes leaning to a reddish orange. However, the famous 'Horn' tubes usually had white writing. Most of the tubes used the standard year-week date code. Either that or no date code at all.
We have many on hand as a local distributor carried Amperex as their premium tube line.

The above four box designs are from the 70's and 80's.
In the row below are a couple from the 50's & 60's. These two boxes are in the correct relative size to each other, although the smaller shows two views of the same box.

| Thanks to Bob Ellingson for these two boxes. | |
