I recall my uncle having one of those. He had a component mono hi-fi but he said once that he thought the GE sounded better. It was a long time ago.
GE is an interesting company in some ways. They made my AM portable P-780 in the 1950s to very high standards. At the end of the tube era they made a couple of 6-tube table radios. One was optimized for reception and identified as a "long distance," and the other was optimized for sound and called, like your much finer device, "Musaphonic." And of course they have made the Superadios (I, II, and III). I have a big console radio, model F-107, from 1937 or '38 when motor-driven automatic tuning was all the big gimmick. And then there's the Model 250, a tube portable radio that had a wet cell battery and a vibrator power supply. The idea was to avoid the expensive A-B battery sets that most tube portables required.
