capacitor questions

[linixsas]

hi
i have a litle problem. ceramic capacitors i have are far from being in spec so can i use polieser capacitors instead of ceramics is there some difference. i'm kind a new in electronics but as i understand ceramic caps are used to reduce the cost. and i have some poliester caps just laying around so can i use them ? i would use ceramic only for c7 c9 c10 c11 c19 c22. i also noteced that in the schematic theres 1 0.015uf capacitor but in placement oc it shows that there should be 2 but on most finished projects i've seen the holes are left empty should it be so?

thanks for any help

Polyester are fine. Ceramic capacitors are generally worse than foil capacitors. If you can fit them, why not!?
