Default Vintage dac recap

Hi,
I have this old dac that I really like. It is probably from the mid 90's. I had the producer make some mods to it and installed Jantzen Alumen Z copling caps. Holy cow that made a huge difference.
I am considering making a few more tweaks. Belleson regulators and changing the older caps for something newer.

But I'm a novice when it comes to this field. Any recomandations for types of caps that will fit? Pretty tight fit. I'm looking for some smooth, full sounding types.

It's from the 80s with the hand tape board layout.

The devices seem datecoded 1996, presumably modded then? What a modfest.

Yikes - be careful in there! I couldn’t find any internal pictures online, but hope most of that work is modifications!

Only useful mod based on your picture would be to replace the main 6k8uf smoothing cap. It also looks like maybe an el-cheapo rectifier is fitted, maybe worth replacing with some Schottkys- other than that the caps that are there are OK IMO. Your photo isn’t complete - is there more stuff above top of picture? And what has been done on the track side? I assume very little given all the soldering on component side
