I can't immediately see where the path you are reading across the C-E of the line driver transistor is coming from but probably via the 110V supply.
Try your multimeter on a higher resistance range to measure the primary side of the line driver transformer, the range for continuity maybe too low to measure this, not that the reading matters as such, as already said if this stage wasn't working you wouldn't have any EHT or scan at all on this set.

It is getting late for me (up at 5am) so I will have a closer look for you tomorrow.
