Brand(s): Supertron, Supertron Precision, Victor

The brand Supertron began in June of 1923, the creation of Robert H. Herschman, d/b/a Victor Radio Mfg. Co. The evidence for this was painstakenly extracted from patent & trademark gazettes from the era.



Herschman's ties to Victor havent yet been researched by me, but it's clear that the success of Supertron as a brand left few reasons to use the Victor brand for tubes sold. They may have reserved the Victor tube brand for units paired with Victor radio sales.

Supertron was a top threat to RCA, successfully producing and marketing tubes despite their lack of license. Supertron was included in the legal proceeding of the late 20's, and it looks like they may have stopped production of tubes in late 1927, perhaps seeing the writing on the wall, or perhaps complying with an injunction. In 1929, Supertron joined in accepting the settlement with RCA and was absorbed by the formation of Marvin tubes.

In February, 1928, Supertron advertised as a manufacturer of neon lamps. It's unclear if Supertron's venture into neon was successful, but it is clear that they were retooling and diversifying in anticipation of losing their court case against RCA. 

Did their Hoboken plant become one of Marvin's five initial tube plants? Further research may tell.


Having handled and tested examples of their tubes, I confess the last revision of their Supertron isolantite 201A may be the best constructed element assembly ever made. It certainly rivals Eveready's four pillar box plate designs. Nearly every example found has a working filament.

Note: examples of 'detector only' and unthoriated 201 tubes have not been found. We can safely assume these were not produced by Supertron, having started in mid 1923 on their tube manufacturing. Advertising using the term 'detector' refers to the 201A
