Well I am definitely no expert on this, but no one else has answered you
besides me so:
If your instructions say "come off the negative pole of a capacitor" then I
would assume an Electrolytic since ceramics dont have neg/positive leads.
Pick a electrolytic that has a voltage rating above that of the voltages at
the circuit.
So if +15v is going thru the circuit at that point, perhaps a 25v rating on
the cap.
SOMEBODY STOP ME IF I AM WRONG ON THIS!

the instructions i have are pretty straightforward. basically, you come off
the negative pole of a capacitor on the board to the positive center of an
input jack, with a .47 mf cap inline. the type of cap was not specified and
i am too much a novice to know if it matters, but cautious enough to ask
before plugging in the soldering iron. the electrolytic, being polarity
sensitive, does this mean the flow of electrons is directional?  as in,
flowing only one way? i'm thinking that the type of cap probably doesn't
matter, except if i use the electrolytic it would need to be properly
oriented(which would be - coming from the input -  negative to positive?). i
know i'm in the presence of masters here, so please bear with these, uh,
questions from the back row, so to speak...

thanks(again),
shayne
