The following models use the same chassis, schematic and cabinet but have different cabinet colors:
Model Chassis Cabinet Color B508R 5Z05 Maroon with white front B508W 5Z05 White with white front
The SAMS Photofact Set 353, Folder 17 calls out model Z508B, Z508L and Z508V. However the SAMS index for the B508 series refers to this same Set and Folder and so therefore is applicable for this model also. The same applies to the Beitman reference.
WARNING: One side of the AC line is connected to the chassis. When servicing this radio, an isolation transformer should be used between the power line and the radio.
