Up for sale here is this set of 2 used American Radionic Inc by DuPont mylar vintage wax capacitors.  These are marked .02 uf 200v and test a bit under .02 uf.  The ones you get may not test at exactly the values in the pictures, but they should test around .015-.017 uf.  These are really nice caps and would be great in a guitar.  Please see my pictures for details.

US shipping and handling is $4, and international is $12, no matter what quantity you buy.  I accept Paypal.  If you have any questions, please ask.

I have a number of other vintage capacitors, collectibles, Magic cards, and vintage electronics listed--feel free to take a look!
