Ceco Manufacturing Company was a Providence, Rhode Island, US, firm which acquired a license to manufacture radio tubes in May 1929.[1] Radio Corporation of America issued the license under Radio Corp. patents. The business was the second corporation licensed to produce radio tubes.[2]

In April 1930, there were fourteen businesses authorized to manufacture radio tubes in the United States.[3] For some time they had a factory in Birmingham, Alabama, but it was closed due to labor discord.[4] The company was acquired for $8.5 million by Richardson Electronics Ltd., of Franklin Park, Illinois, in September 1985.[5]
