I think a picture will be necessary.

Can you post to alt.binaries.schematics.electronic ?

Hello Matt

thanks very much for the first link it very useful

now do i read the colours from the bottom up or the top down.

Also this cap only has three colour bands does that matter?

The circuit only runs on 25v dc

Really hard to say without a picture of the cap. Is it ceramic, mylar,
tantalum, electrolytic, etc.?

Try this; it is a URL to an instruction of how to identify a cap:

Maybe it will help....
