[R-390] line filter for EAC R390A

Dick,

A lot of the filter was 1940 military thinking. 
These receivers were run off generators and third world power sources.
The filters were to help to cut out some of the whine and pop of theses 
sources.

The filters also help on days with local thunder showers. The noise does 
not mess with the line voltage much but the lighting strikes do put some pops 
on the power source lines.
