Arco Tube Company
38-40 Park Place, Newark, New Jersey (1930)
227 Central Avenue, Newark, New Jersey (1940)

The Arco Tube Company frequently advertised in Radio Craft Magazine. A September 1931 ad states that "These tubes are made by one of the largest Eastern tube manufacturers". The May 1933 issue announces the "Arco Tube Bulletin" - "a descriptive folder giving full characteristics on the complete line of Arco radio receiving and transmitting tubes, photo-electric cells, television lamps, hot and cold cathode tubes, cathode ray tubes, rectifiers and charger bulbs". In October 1939, Arco advertises "We either have the tube you require or we will make it for you".

The 1931 advert seems to indicate the company was a wholesaler and not a manufacturer. However as of now the picture is not 100% clear. They are also listed as manufacturer/distributor of resistors.

Tyne's "Saga of the Vacum Tube" lists Arco Tube Laboratories, New York 1928 but nothing has so far been found to link these two companies.
