Brand(s): Bluetron


American Radio Laboratories' Bluetron brand entered the market in the first half of 1926  At just $1.05 price, Bluetron newspaper advertising briefly appears for just one day in Oakland and San Francisco, California, and then is only seen in Wilmington, Delaware - being sold by Premier Radio Co. 

With just 9 mos of sporadic advertising, Bluetron likely suffered the demise of their OEM contract as RCA litifation with most tube manufacturers shuffled and consolodated the industry.

What west coast tube manufacturer would have supplied blue envelope 201As for OEM branding contracts?

Who made them isnt clear but may reveal itself with more information. -Chris
