Your bad vertical electrolytics will all be in the C300-C318 range, at the right, toward the front of the board. Replace any/all electrolytics within those cap numbers. One should be a 4.7uF at 160V or 250V - make sure it gets replaced. C314 or close to it...

There is also the red electrolytic cap over near the Jungle chip (big chip in the center of the board). Red deaths, we called them. Most were low value, 1/2.2/3.3/4.7uf or so. Replace it.

There is a 22uf/160 near the flyback - replace it. Modern 250V caps are the same size - go with a 22uf/250V cap. You'll get jailbars or intermittent shutdown when it goes -

I'm working from notes, as it's raining cats and dogs tonight, and I ain't going out to pull a Sams....
