Other questions now come to mind. Why are paper caps usually tubular but
mylar or poly are rolled but on a very flat oval cross section? I've been
told to stay away from the green and brown dipped caps that come from
asian
areas as they can be a source of problems.

Plastic film caps can be rolled into a round tube. Bob's Antique Radios &
Supplies has them:

These are much like the old Sprague Yellow Jackets. Similiar or identical
caps are at Antique Electronic Supply.

As far as I know, the flat oval style is only used for radial lead
capacitors. I suppose there's an advantage in trading width for height in
PC board construction.
