bassdrive/fulldrive Q(yet another capacitor question)

[blackbirdneo]

sorry i had to post a new topic because i cant seem to find the answer using the search function.
i have completed all the parts needed for making a fooltone fooldrive clone except the 1uF NP capacitor. can i use mylar(since the only available capacitors in my country are mylars, ceramic, elecrolyitc and tantalums) ones or should i make a NP capacitor using elecrolytics(how do i do this by the way)? thnx in advance.
