<p>A CRT deflection circuit for use in a flying spot telecine scanner comprises a linear amplifier A1 with a resonant flyback circuit 50 and a flyback shift circuit 70 comprising an inductive DC path L2 carrying a DC offset current and a capacitor C2 carrying the raster scan AC current to the flyback circuit. Since the DC offset current is not applied to the flyback circuit 50, the circuit can fly-back to non symmetrical beam positions, so that the entire scan can be displaced by a shift applied to the input of the amplifier A1. <IMAGE></p> |
