As I pointed out there was a design error in the TV22 in that the V sync was grossly over integrated. So the 100k needs reducing, in the circuit as it stands, if you want to have better interlace. Another option is to change it to around 15k and replace the diode with a 15k resistor, will give a good two stage filter.
Still the interlace will possibly be poor if the HT filter caps are in poor condition (the originals always are in poor condition) or the the hum cancelling cap off value. So it is important to rebuild the capacitors for a good result.
