LinkM,

I appreciate your idea to inline the inductors and naturally shrink-tube saves the day for so many inline solutions like this.

I did strike upon the idea of soldering the caps to the traces under the board because the board is on standoffs anyway.

By the way in my searching the net for use of inductors and caps for noise filtering, I discovered some LC filter arrays in a single IC type package with 4 per chip, by TDK (series MEA) but it looked like they were narrowly designed and spec'd. for telecom use. Not understanding enough about LC filters I didn't know if the product series could have helped my situation. It was a very slick idea though having 4 filters on the chip. If that worked, it would be nice to put that on the main board in any new design I might come up with in the future.

Thanks for all your help.
