first build so just checking...(bsiabII)

[liam012]

i have my parts all ready but i just need to check a few things:
1) for c1 instead of 250pf ceramic disc i have 250pf silver mica - ok?
2) for the 2 1uf caps (c3a + c9) i have non polar electrolytics (1uf NP) instead of film - ok?
3) for c5 it says a 470pf mica or polyester - what i have is 470pf bit i dont think its a mica as it doesnt say sm and its light yellow - it says:acld15 - d471f - 0438..... kind of looks like a mica except yellow - will it do?
4) aluminium electrlytic - how do i know its aluminium? i have a black and wite Ferer vent radial 100uf cap  for c11 but dont know if its aluminium? how do youtell

sorry if i am being pedantic butr its my first build and and am unsure of the required attention to deytail..

1) Fine the type really only affects subtle sound differences, but won't mess up the circtuit.
2) This should be fine, again mostly just like above
3) As long as its 470pf you are fine.

Capacitors can be interchanged as long as they are the same value, the type just can alter tone, (not always better or worse, just personal preference). The only problem would be putting a polarized electrolytic in place of a NP one. But the other way around works fine (NP for POLAR).

Good luck and have fun!
