AB  - The signal from a preamplifier or tuner is supplied to the input terminals of the power amplifier by means of a voltage dividing network, the element in parallel to these input terminals being a photo-sensitive resistor of new design. Facing this photo-resistor in a light-proof enclosure is a neon lamp connected to the output of the amplifier. A neon lamp ignites at a fixed voltage, and the value of the photo-resistor resistance will begin to decrease as this voltage is reached. Consequently, the input signal to the amplifier will be decreased as well, making overload substantially impossible.
