So after 30 years, it finally happened and the capacitors leaked. I've tried a recap with Kemet's as the primaries and a mix of nichis and Wurths everywhere else, and it won't boot. No fans spinning. No LED activity. I've double and triple checked the soldering and negi-lead orientation. No catastrphic trace destruction and instead more minor blistering at some points. Thus I can only assume its ESR.
Now the main issue here is these are 30+ year old capacitors. The internet wasn't in the best condition in 1989 so I'm really struggling to find any mention of most of these caps at all so I need help with what capacitors would make sufficient replacements please.

I'm listing this one for anyone else trying to recap one of these PSUs. This family is still available, with data sheet here:

This family is not available anymore, but this document from Nippon lists the LXY family as a suitable replacement.
