Hi All

I deal with a lot of line filters at work.  All the ones I have ever seen
are exactly the same electrically going from "in to out" as opposed to "out
to in".  The terminals may be different on each end, but they are
electrically the same either way...

I also checked a bunch of standard line filters I use here and they are
symetrical too.  The only TC filter I know of the is "out to in" critical
is my NST ouput filter (see how I am :-)) at:
