match it to other models.
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.

Thanks, I'll be posting a pic later tonite once I snap one. What I might do when I can is replace the 9-186 and work on the old one, I always like to "hedge my bets" for just in case. High end set? Well, is cable ready, we've gotten a free channels for free for the longest time after we bought it. A quick story, in April of 1983, we were in Kaufmann's in Pittsburgh looking for a new TV. Mom saw one for $650, had the manual tuning and I looked around. I saw the SY2585P in a corner with remote control for $550, I asked "Why is that one cheaper if you get more," the salesman said, "we are trying to get rid of it, it is a 1982 model." Sold, Mom said. Right now, until I get it fixed, I'm still in the 1980's, I have a Zenith DT-900 hooked up to a 1984 Commodore 1702 monitor as a jury rigged TV.
