OK, so it is now November... and I just finished these things, but I thought I'd share anyway.
During the Summer I was asked to build a pair of 3155 networks for a fellow Forum Member. He decided that he would prefer outboard networks so I built some cases that I thought would be in keeping with the design of the 4355.
The design of this particular circuit was adapted by Giskard and based on the original 3155 as designed by Greg Timbers at JBL. The exact DCR of the coils was critical for optimal performance. The Mills resistors are 1% as were the values for the inductors and capacitors which were individually measured.
This design like the original is not charge coupled, but it was built using metallized polypropylene capacitors that were bypassed with AudioCap Theta Film and Foil caps.
Here is a shot of the board.
