ABSTRACT:
A video output amplifier has an output terminal coupled to a signal input electrode of a kinescope. A signal limiting circuit coupled to the output terminal limits the magnitude of large video output signals to prevent saturation of the video output amplifier. The limiting circuit includes a resistor and a limiting diode coupled from the output terminal to a bias potential.
