I'm working on cleaning up a bit of battery
leakage in a MicroVAX 3100 Model 10 and while it's apart I decided to look inside the
PSU (an H7822-00).
It's nice and clean inside with no bulging caps. What it does have is an X2
capacitor, as shown here: https://photos.app.goo.gl/dpdqJ3tuGfsRDR3Y6.
It doesn't appear to be damaged and I can't see the word "RIFA" on it
anywhere but I can't see two of the sides because of other components that get in the
way.
So does anyone know for sure whether it is a RIFA brand or not, or do I have to desolder
it to be sure?
Thanks

It looks like the RIFA caps I've removed from my DEC H7864 P/S. Though mine were
colored more toward the amber you find dead flies fossilized in and had visible cracks in
the case. The RIFA logo/name was on one side with other markings on the other side, on
the top was only the X2 and the value.
You might have to remove it just to be certain that it is a RIFA, but the top lettering
and the overall look point in that direction.
