ABSTRACT:
An improved CRT beam adjustment device is provided for exterior orientation on the neck of the tube. The device includes a plurality of rotatably adjustable annulate magnetic members sequentially positioned on a support sleeve, one end thereof being formed to have a plurality of tongue-like extensions, each having a terminal protuberance extending radially outward therefrom. Each protuberance has a surface facing the annulate member that is downward sloping toward the body of the sleeve. An adjustable ring clamp is positioned to ride on the slanted surface of the protuberance and abut the adjacent magnetic members, thereby providing by one adjustment, pressure to positionally lock the adjusted members while simultaneously affixing the device to the neck of the tube.
