cap question

[Reverend bluE]

okay, I finally found a VCO design that I like (read:  I can find the parts
for it.)

It is the Maxx2 Master VCO  (VCO-4B)
http://www.mindspring.com/~vco/maxx2/page_007.html

the only problem that I have is the word "POLY" printed in red on the
schematics under the 2N4392 trans.  It would appear that this word refers to
the Cap that it is printed by.  "POLY .002"  

does this mean I need a Polyester Cap?  I find them, but the tolerance is
poor (+-20%)  the other Polys I find are the Metalized Polypropylene Film
ones, but these are physically big (32mm), and it would be the most expensive
part of the circuit (just about)...

beyond that, I can't find a .002uf CAP anywhere.  it jumps from 1 to 2.2uf.
So what is the deal here?  

I guess I have two questions.  The one about the word "POLY" and one about
.002uf CAPs.  yeah.  I think that's all.

thanks for your time.
