OT&T Electric Co.

OT&T Electric Company, 1819 Broadway, New York, NY, USA

Brand(s): Silvertone, Deforest Silvertone, OT&T




O&T Electric Company is, perhaps, the most brazen of the silver era bootleg manufacturers. While there isnt much evidence that the company advertised outside winter 1923, there are enough examples remaining of their tubes to suggest they had some success.

Advertising had a greater impact in a century ago Magazines and newspapers were often saved, shared, and re-read. Ads were read and acted upon for about 12-18mos, depending on the requency the reader upgraded their set. If you had an 'old set' then newer magazines had moved past your radio's technology. 


OT&T made the bold move to brand their tube as 'made by Deforest Tel. & Tel. Co.' It was not made by Deforest!


As a collector, I still more often than not, find these tubes sold as 'Deforest Silvertones'. It just goes to show that a well spread lie can travel a long way, even a century.


To say these tubes are proven to not be associated with Deforest, is underscored by records showing the Deforest Company suing OT&T Electric Company. It seems they shuttered their factory and fled before judgement was passed on them. They didnt show up in court, and it is assumed they were never made again.


I will update this page further once I finish the legal research that is ongoing with the National Archives.
