Sometimes referred to as the "Children's Radio/phono", this neat little set is from the 1946-47 era. The case is made up of 8 separate plastic castings. The two piece lid incorporates the built-in loop antenna sandwiched between the top and an inside insert which is held in place by what appears to be rivets (and probably glue too). The ivory sections are made of two types of plastic, the top is a soft material while the grill and other smaller pieces are made of Urea or Plaskon (a hard plastic).
The phono is a single speed (78 RPM) driven by a direct drive motor with a pinion drive gear box. The pick-up is the old standard style crystal type cartridge.
The radio circuit has a couple of unusual design oddities. One, it incorporates a selenium stack for the rectifier (it has been replaced with a silicon diode). Two, it uses a pair of 50B5's in parallel for the output stage with the heaters in series. That makes the heater string about 16 volts shy for the tube's rated heater voltages. It does not seem to mind though as it works exceptionally well. Otherwise it's the typical AA5 circuitry.
