Ask a question... get some answers - that's how BCN usually works.

Nice find!
I have something similar saved as an image/file on my PC so I can refer to it when I encounter older PSUs. Seems like not many people/places/sites are keeping track of UL numbers anymore... if at all. In fact, even UL's website kind of went dead (or at least it's not search-able by us mere mortals.)

I suppose I don't care much anymore either - I just open PSUs and use my gut feeling to tell if it looks alright or not.

Probably a good thing.
I got baited with my TASK PSU and put in a full 10 mm dia. cap in there. PSU didn't like it.

Yeah, it probably is.
It's even more sad when you see a PSU use leaded solder and the joints are still bad.

I don't blame you.
Small Teapo caps always tend to be problematic after a number of years.
