| Description |
The O-T series of tubes were manufactured by the O-T Corp and not by the de Forest Telegraph and Telephone company. de Forest sued O -T for misuse of his company name and won the case. This is despite most tubes showing that the tubes were made for O - T. The advertisement in Radio News, March 1924 also carries the same erroneous informnation.
