A projection television apparatus has three monochromatic picture tubes disposed in a planar orientation defining a central picture tube and two outer picture tubes. Each of the picture tubes includes a deflection unit responsive to deflection currents and raster correction signals for vertical and horizontal deflection. A control circuit, including a signal generator, supplies vertical and horizontal raster correction signals formulated for the central picture tube to all three of the picture tubes and supplies additional vertical and horizontal raster correction signals formulated for the two outer picture tubes respectively to the two outer picture tubes, respectively. Conductive paths for the formulated for the central picture tube correction signals can include variable resistors for effecting small changes in signal amplitude.
