Stromberg-Carlson, USA

From the original site

Stromberg-Carlson was a telecommunications equipment and electronics manufacturing company in the United States. It was formed in 1894 as a partnership by Alfred Stromberg and Androv Carlson. It was one of five companies that controlled the national supply of telephone equipment until after World War II. Stromberg-Carlson was originally located in Chicago, with Carlson managing manufacturing and Stromberg responsible for marketing. Stromberg-Carlson quickly established a reputation for reliable equipment and stable prices. The company also became involved in the broadcasting industry, acquiring WHAM, the oldest station in Rochester, and rebuilding it into a high power station; one of the first three FM broadcasting stations in the United States and possibly the oldest still in operation, now known as WBZA, dating from 1939.

Stromberg-Carlson: the short history

The original page breaks off with a "read more" link that no longer goes anywhere. The rest of the story, from Wikipedia: Rochester's Home Telephone Company bought the firm in 1904 and moved it to Rochester, New York. After the Second World War it added televisions and high-end stereo equipment to its telephones and radios. General Dynamics bought it in 1955, sold its broadcast stations within a year, and sold the remaining operations in 1982.

Two Stromberg-Carlson amplifiers are on file, the Signet 70 and the AU-58B.
