This is for EL84 of course.
I would always replace this cap on sight, as they have a harder life than certain others.
Not always.
If it's a Rogers amp fitted with Mullard mustards.
I saw someone recently who replace all the mustards in what WAS a nice HG88 with modern yellow things, and made a proper dogs' dinner of it too.
A little knowledge and all that....
