worlds smallest? 5 tube AC/DC radio
     measures only 5 3/4" across!

Circa 1952, I don't know much about this tiny set except I believe it to be quite rare, if not rare very scarce. I have only seen a couple of them and one was in pretty bad shape. I suspect they were played (the performance is excellent) until they self destructed from heat. It employs the standard "all American 5" tube line-up, Superhetrodyne circuit with inductive tuning. Another assumption I have is these were probably given away with an appliance purchase like the Westinghouse "refrigerator radios" were.
