Original 1943 electrical trade vintage ad for AMERICAN TRANSFORMER COMPANY.  Main office and plant was located at 178 Emmet Street, Newark, NJ.  (Since 1901).

Manufacturers of AmerTran. Pioneer Manufacturers of Transformers, Reactors, and Rectifiers for Electronics and Power Transmission.

AmerTran helped Marconi send his first message across the Atlantic!  

One of Marconi's headaches in the earlier development of long distance wireless communication was the lack of suitable transformers. It is,, therefore, significant that he chose transformers manufactured by the American Transformer Company for his Nova Scotia station that sent his first message.

Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
