Dear
@paulcreed : As I said you can't go wrong with. Btw, in my external XOs I wired everything point to point/hard wired, it makes a difference for the better.
My 100% pure silver ribbon inductors came from Alpha-Core and are second to none ( I know this because I tested several inductors before those ones. ) in this critical XO quality performance function levels.
Here the Jantzen distributors options:

due that I can't find out in my country Jantzen accepted that I buy it directly from them.
Regards and enjoy the MUSIC NOT DISTORTIONS,
