The trouble is bending to the right whenever the top half of the
picture is predominantly white. A new PCF802 line oscilator
valve has been tried without success.
Try a new PFL200 video/sync valve, also check the
coupling capacitor C111 (0.1,uF) to the sync section of the
valve and the value of the 471(52 resistors (R74 and R75)
supplying the sync separator’s screen grid. There should be
about 94V at pin 3.
