ABSTRACT:
A power supply for a television apparatus comprises a source of energizing potential (5.2V) fed to first and second control transistors (Q26403, Q26404). The first control transistor outputs a first source, while the second control transistor outputs a second source. The two control transistors are controlled by a feedback type voltage regulator (U26404) so that the sources track each other. The feedback voltage regulator is controlled by the second source. A storage capacitor (C26466) is coupled to the first source through an isolating resistor (R26462).
