[ARC5] What the......?

[Geoff]

Miniatures were already out as a full set for battery radios in answer to 
Sylvanias 1Lnn series Loktals. The handwriting was already on the wall by 
the time the 6V Loktals arrived in force in 39 and the 14 series which were 
mostly 12V octal equivalents, for AC/DC sets in 1940.

The actual reason for Loktals was a push to Sylvania by Philco, Zenith, and 
a couple of smaller OEM's to not have to use anything developed by RCA. It 
was the result of a long term animosity going back to the 20's.
