The same circuits with Hitachi CMT2988 pincushion correction circuit are as follow: Hitachi 25M8C, CMT2518, CMT2718, CMT2916, CMT2588, CMT2598, CMT2998, Furi HFC2581, 2586,2587,2986,2987 and so on. The approximately 4V (peak - peak) sawtooth voltage on two ends of R617 is added to the IC651's (1) foot by the C651, R651, then it will be made internal amplification, integration process, pin 2 will out about 2V (peak - peak) concave parabolic wave voltage. R655 is the line width adjustment potentiometer, and R657 is the school pincushion correction adjust potentiometer.
