I have a lot of high quality caps here left over from upgrading speaker crossovers. I just spotted some used 2.2uF and 4.7uF WIMA films. I also have brand new Nichicon ES 4.7uF 50v. None of them are axial though (not that it matters, I guess). Since I'm trying to cut back from a massive 250uF, anything should help but which of these would be best to use for this? Or should I go order some "proper" 2.7uF MPP axials?
I would just go with the radial film caps you have on hand. The axials have gotten a bit expensive and harder to find.
This is in the point-to-point wiring, underside of the chassis. I could fit a gigantic cap under there if I wanted.
Since the Wima is a radial film, whichever one I decided on will most likely get installed upside-down, with the top of the box hot-glued to the chassis.

I've swapped in the 4.7uF film caps and OUCH there was an enormous turn-on pop that wasn't there before. Also a much smaller pop came through at regular intervals that reminded me of a needle hitting a scratch on an LP.
Unless you guys have any advice on that turn-on kapow, I'm going to find some new 250-350uF BP electrolytic caps and be done with this part of the story.
