  The BC band frequency range is 540 to 1600kHz.

  Early production models used a 500Kohm volume control, which was changed to a 1 Megohm volume control on late production models.  The schematic used for model X552 is the same as is used on model X551 (Which uses chassis RC-1089B). Both models are shown in SAMS Photofact set 129 folder 9 from April 1951.
