ABSTRACT:
A structure for a resistor to be built into a cathode ray tube. The built-in resistor divides an applied anode potential into an intermediate focusing potential. The built-in resistor has a main resistor and an additional resistor means. The additional resistor means is serially connected to the main resistor. The additional resistor means provides a plurality of resistors, one of which is selected for fine adjusting the divided potential.
