The same circuits with Toshiba 2500XH pincushion correction circuit are as follow: Toshiba 2506XH, 2800XH, 2806XH etc. The field sawtooth voltage is sent to the B pole of QD03 by PD02 (3) feet, RD17, CD14, RD16, RD19, CD10. QD04 is 50Hz/60Hz switch. When the electronic switch is at 50Hz, QD04 ends, and at 60Hz, QD04 is conduction, RD19 is short, sawtooth amplitude sent to QD03B increases. QD03 is parabolic wave voltage generating tube, which can generate the concave parabolic wave voltage at C-pole output, then it is adjusted by the RD51 margin and added to the B pole of QD02, and QD02, QD01 are the parabolic wave amplifier tubes, RD50 is the line width adjustment potentiometer.
