Hi Rich12:
it is likely that the 8 uF 350 volt paper cap you reference is an electrolytic. If it is wrapped in a cardboard tube, this may be leading you to believe that it is a paper cap. As old-tv-nut says, a picture would be the best way to clear this up.
What we mean by paper is the dielectric material that separates the metal plates of the capacitor. In a tubular cap, the plates (usually some form of foil) are wrapped together, then sealed in ceramic, wax or plastic. The cap could have a plastic outside covering, and still be paper dielectric, and therefore needing to be replaced.
the value of the cap combined with its working voltage is the giveaway. You are correct in your observation that the poly replacement caps do not come in 8 uF values.
Make sense?
