which capacitor to use?
QUOTE (db ice 3 @ 7 Mar 2011, 20:52) <{POST_SNAPBACK}>my Fleischmann dcc system seems to output about 20v to the tracks so maybe the 25v capacitor is the one ill fit. i dont know of these digirails lighting boards have any kind of "charging circuit" - they have the connections for the capacitor so im hoping perhaps that they do.
