The RGA 12 and RGA 15 are table model radio receivers and the RGD 20 is a table model clock radio designed for the reception of AM broadcasts. These instruments are housed in

29、one piece plastic cabinets with “snap-in* * masonite back covers to which is attached the loop antenna and power cord interlock connector. With this mode of power connection, the line cord is disconnected from the chassis thus removing all power when the back cover is removed and the chassis is exposed. The use of captive knobs, which cinnot be separated from the cabinet, and line cord disconnect removes the possibility of shock hazard m these instruments.
