i included the product descriptions because i thought it might help. please tell me if these parts are ok before i begin this project. the thing that i am unsure about is the npn transistor, because the parts list says 2N5088, but i cant find those.

thanks!

See if you can get a lower voltage  .1uF cap. Higher voltages will be larger in size. It may not be too big, but you never know. (It should be ok).

See if you can find: 2N3094, 2N2222

I used Cornell-Dubilier (CDE) DME type poly caps which were pretty small (0.1uf is 10mm wide) even though they were rated for 250V. The Vishay Orange Drops on the otherhand were pretty huge, easily twice as big as the CDEs. The CDEs cross reference Panasonic ECQE types (which I think are the ones available through smallbear).

For the transistor, I prefered the results using MPSA18.

i cant find any other transistors in town, so what would the effect of a different transistor have?  size is not an issue to me, so will the higher voltage still work?  size is not important for my first project

You can order transistors from the STORE link above as well.

i cant order anythign online, i dont have a credit card. i was wondering if there were any other transistors that would work so i can actually do this project. i wanna buy locally

Go to your local parts store and give them these numbers:

2N3904 or 2N2222 and ask for a substitute part.

That's what I used to do.
