The models using pincushion correction: Korea Samsung MC-15 movement, Venus C6418, V6458, LOWA CT6388W, Peony 64C1. VR451 is the amplitude adjustment potentiometer, VR452 is the Pincushion adjustment potentiometer. Sawtooth voltage is sent to the pincushion correction circuit by P404's pin 4, R455, C454 and R457 form an integrator which integrates sawtooth wave to form a convex parabolic wave voltage.
