Axial film-and-foils are very hard to find, apart from very expensive 
specialty caps.  Almost all run-of-the-mill axials are metallized 
film -- you would be better off leaving the paper caps in it.

Sure they do.  Sprague was acquired by Vishay (one of the most 
respected names in electronic components), so they are now sometimes 
called Vishay or Vishay-Sprague.

But why use film caps for bypass applications, anyway?  Disk ceramics 
are superior in every way.  You only need film caps for audio and IF 
coupling, audio filtering, and the AGC filters.

Best regards,

Don
