In a raster correction circuit, impedance in controlled by a parabolic vertical rate waveform (50) to alter the charging rate of a storage capacitor(42) coupled to the rectifier(39) for supplying the vertical operating current. The parabolically varying rectifier current alters the loading of the horizontal transformer(20) and alters the horizontal scanning current at a vertical rate in a manner to correct for side pincushion distortion.
