You can use any 9-181, 9-186 schematic to start, they are close enuf.
The retrace is probably the filter cap for the 200V that supplies the
3 video outs. Its a 5 or 10 mfd, replace with a 450V. Maybe its the whole
problem.
For subs you need to find someone with a CRSP or parts price list.

BTW, I did come across a schematic of a 9-186-03 in a PDF for people who repair video games, IIRC, the Zenith board was used in Pac-Man Jr. games and in some other games, they used Electrohome components which is or was a Canadian company.
OK, here is the pic of the set, if you need more, let me know.
