Abstract
The invention relates to a resistor assembly for dividing an applied voltage into an intermediate voltage being below the applied anode voltage in a cathode ray tube. The resistor assembly comprises an insulating substrate and a resistive voltage divider including a first and a second resistive layer provided on the insulating substrate, and an additional resistive network with a first network terminal and a second network terminal. The additional resistive network is coupled in series with the first resistive layer. Furthermore, the additional resistive network comprises first and second resistive portions which are releasably coupled to the network terminals via bridge connections. According to the invention, the first and second resistive portions have substantially different resistance values for selecting a predetermined resistance value from a range of resistance values of the additional resistive network.
