voltage from a small generator on the disc shaft. The sum of the voltages is then rectified and the resulting direct current applied to the magnetic brake. A departure in the disc phase with respect to the scanning produces a corresponding correction on the part of the brake. The disc diameter in a receiver is about twice the outside diameter of the receiving tube, plus one or two inches. The best location will be determined by such factors as the distance from the disc shaft to the picture frame. A typical filter disc for a receiver is shown in Figure 69.
