1956 Little Giant Transistor Radio
Popular Mechanics March 1956
And the final Final Little Giant Boardcast Receiver, as Transistors became widely available, tubes were being replaced as the primary method of construction
The tubes would be around up to mid 1960s, but the public was wanting transistors for the smaller form factor of the radios
I would have preferred Popular Mechanics kept up the Little Giant series, recreating the Little Giant series with transistors, this might have helped people make the switch from tubes to transistor a little easier, looking at the same radio in Tubes and Transistors side by side
No Tubes Used
