To remove the fuse, turn the fuse cap located on the line voltage selector switch in the direction indicated by the arrow. Then remove the fuse plug from the unit. Put the fuse plug back so that the proper line voltage marking can be seen through the cut on the edge of the plug. Whenever the position of the selector switch is changed, check the rating of the fuse. A 1.5-amperefuse is to be usedforeither 22OY or 240V operation and a S-amperefuse for 110V, 120V or 130V operation.If the rating of the fuseis correct, replacecap.

A WORDABOUTROOMACOUSTICS

The quality of reproduced sound varies according to the size and shape of the room, the materials of walls, floor and ceiling and the amount and arrangement of fumiture.

Too harsh or "bright" a sound usually results from too many hard reflecting surfaces, and/or too low a ceiling. This condition is improved by having ample carpet area or covering the wall (especially that facing the speakers)with a thick curtain.

On the other hand, too many absorbing surfaceswill tend to "soak up" the sound, resulting in a certain "deadness".

Furniture may be rearrangedto provide irregular reflection of the sound. In any event, the true stereo effect is lost if the two speaker systems are placed too far apart. This may be corrected by angling them slightly toward each other or reducing the distance between them.
