The stock 1400 Array low pass network is very expensive (compared to the quality of components) so I'm not going to buy one just for a pattern. And charge-coupling them without using any N.P.E.'s at all is very expensive so I went with the usual combination of N.P.E.'s and metalized polypropylenes.
The stock high pass networks are, on the other hand, a bargain in that all the inductors and resistors are 100% viable and reusable for charge-coupling.
BTW - Like Greg, I've switched over to using diodes instead of 9 volt batteries in all my charge coupling endeavors.
