[R-390] Line Filter Replacement

[Barry]

The subject of leaky line filters has come up on this list several times
over the years.  Most of us are aware of the danger of the "hot" chassis
they present, how they will trip GFIs, etc.  The radio can be run on an
isoloation transformer, but a good transformer can be expensive.

One solution is to replace the filter with a modern line filter that doesn't
have the current leakage problems of the original filters, but finding a
replacement that will fit without modifying the chassis seems to be
impossible.

While it's not as elegant as I'd really like, I think I have a solution.

As you can see, the modern filter fits neatly into the custom-machined
housing, and the modification is completely reversable.

I didn't like having to splice the neitral wire on the right-hand side, but
it would have required me to pull some of the wire out of the harness to
make it reach the new filter and I didn't want to do that.  If you know
where I can get some of the old-fashioned solder posts (the round type with
#6-32 internal threads), please let me know.  I found one place, but they
are very expensive and I can't seem to get the guy to respond to my emails.
