Harry, make the capacitors MUCH smaller. Think of 1 nF, 1000 pF. A capacitor of 470 uF will definively give the problems in scanning that you observe. This is for BOTH amplifiers (the part behind the 4k7 resistor). In fact they are the same amplifiers and there is no difference between line and field scanning.
In theory there is no capacitor needed at this point, but because the amplifier has feed back and the transistors have some delay, oscilation is a danger.
On the other hand, now the circuit diagrams are readable.... I see the final transistors should be AD161 and AD162. They are germanium transistors. How did you get these old transistors? They have a very small threshold voltage and as the circuit is, they cannot without any changes be replaced by modern silicium transistors. This is also a ground for the seen imperfections. However I think if you put much smaller capacitors in place, this also will help. Then the feed back loop is fast enough to mask any cross over problems.
