Thanks for the info! The audiophile connection isn't surprising
considering their general nostalgia for archaic technology. Let me guess
-- the wax-coated ones are surely best because of the soft sound they
impart. But I see that paper *is* still a viable dielectric for
capacitors requiring the best self-healing properties. A quick scan of
the web seems to indicate that's their remaining market. I see that
plastic dielectrics are being touted for good self-healing properties,
and at least one vendor uses a combination paper-polypropylene
dielectric. So it looks like paper might be getting slowly pushed out.
But there's no doubt they're still being made and used, all right.

I've just been lucky and not had to deal directly with components for AC
mains RF suppression, except potted units.

Does anybody actually make paper dielectric capacitors any more? I
thought they'd been gone for a couple of decades now.

Sure. For whatever reason, some audiophiles still want them:

Paper caps show up in other places:
