Interest comments & thanks for them..... I presume that most dual standard sets used mean level AGC on both 405 & 625, & when single standard 625 sets came on stream in 1969 that they used sync tip AGC & that would look better with a stable'ish black level than the DS sets. Also did DS sets use AC coupling on the video gubbins without bothering with DC restoration? Just some other random thoughts I've had..
