Problem with capacitors

[Kaue92]

Hey dmitri, i've started to build megadrum about three months ago and I'm not able to find a few capacitors. I'm from Brazil and I can't find the 22pf 200v, 100nf 50v and 470nf 50v capacitors at all, only with higher voltages, that's the only thing lacking so I'm stuck with it.. can u help me with that?
Thanks!
