The models using pincushion correction circuit are: Samsung MC-15 movement, Venus C6418, V6458, peony 64C1, Leroy CT6388W and so on. The field sawtooth voltage is sent to pincushion correction circuit through P404 (4) feet, and R455, C454, R457 form the integral circuit to generate integration on field sawtooth wave, then it forms the convex parabolic wave voltage to add to the B pole of parabolic-wave shaping amplifier tube Q451, by the amplification, shaping the output from the C-pole 9V (peak - peak) of the concave parabolic wave voltage, and then by VR451, VR452, R464, R463, R462 component level adjustments, added to the Q453, Q452 composite pipe B-polar. VR451 is the line width adjustment potentiometer, and VR452 is a pincushion adjust potentiometer.
