 Unlike the Edison phonographs about the only thing noteworthy about these sets is the name "Edison", other then that they were average or bellow average. Edison, or rather his son who had taken over the company, got into the radio business by buying out Splitdorf. Unfortunately the stock was overvalued, as many radio stocks were in that era, and it's assets, products, and licenses were not really worth what they paid for it.
 Two good points about the set pictured was the electrodynamic and the nice cabinet with doors. However from the chassis pictures it looks like the set uses a set of #26 tubes followed by probably a #27 under that tube shield, most sets were using screen grid #24s for RF amps by 1930. I don't know what tubes it uses in the power supply/amp chassis, if it uses a pair of #45s as power outputs then it's probably half decent, but if it uses #71As then it was definately an antiquated product by the time it was made. Yes Philco 20s used #71As too, but those were budget sets, the better console models, like model 96s, used push pull #45s.
