Work on these models should only be performed by those who are thoroughly familiar with precautions necessary when working on high voltage equipment. Exercise care when servicing this chassis with power applied. Many B plus and high voltage RF terminals are exposed which, if carelessly contacted, can cause serious shock or result in damage to the chassis. Maintain interconnecting ground lead connections between chassis, escutcheon, picture tube dag and tuner when operating chassis. These receivers have a “polarized” AC line cord. The AC plug is designed to fit into standard AC outlets in one direction only. The wide blade connects to the “ground side” and the narrow blade connects to the hot “side” of the AC line. This assures that the TV receiver is properly grounded to the house wiring. If an extension cord must be used, make sure it is of the “polarized” type. Since the chassis of this receive is connected to one side of the AC supply during operation, service should not be attempted by anyone not familiar with the precautions...
