A common problem with on line schematics. They are fold outs
& usually not included. Too much work & when they are there
they are usually unreadable.
If you can find the vert out IC & measure all the voltages on it.
You can compare them with the IC's data sheet on the net.
Post it all here & we can probably figure it out. These ran nice & it
would be good to see it running.
