| Zusammenfassung: | In a television receiver, a higher beam current is enabled and a brighter image is provided, without adversely effecting the life of the cathode ray tube or endangering the high-tension transformer. The high-tension transformer includes a temperature sensor which acts with a control circuit for reducing the beam current when the temperature of the transformer rises above a specific temperature. |
