ok so i am getting there slowly i think
c15.jpg
my tv has an additional panel on the right of the chassis with 2 additional linearity pots for the vertical that are not present on the american sets and consequently not listed on the schematics that i have
capacitor c15 is absent on my tv and on its place there is a capacitor connecting to that said panel
removing that capacitor and putting a 4n7 capacitor on the position of c15 makes the foldover go away and the pulses for the vertical drive are looking very good now
now i just have a totally squished top on the picture
i am at the point where i am thinking of removing the two linearity pots and recreate the "american"style circuit, that has to work but i consider it cheating.

here each cycle is completed in 20miliseconds and that is equal to 50hz so we are good. the sawtooth looks preety also with a very short fall time (perfectly vertical slope)
