circa 1946 - 1956
The links below are all
the (sold in the US) "sub-mini" tube radios made for consumer use that I am aware
of. I have seen promotional advertising for others but to my knowledge none
have surfaced (such as one advertised by Sylvania). I would be very interested
in learning if they are additional brands and models not listed below.
Very little documentation is available on these most interesting sets. The
few that were made was at the early stages of transistor development
which took over the portable radio market in the mid 50's. Some of the
later submini tube sets omitted the output tube and replaced it with two
transistors and referred to these sets as "Transistorized". Some of the
earlier submini sets incorporated one or two miniature tubes as well for some
reason such as the Motorola & Silvertone.
