Fw: [R-390] R-390A AC FILTER

Couldn't figure out a clean way to modify the original filter ....so

That's what I just completed on this R-390A: 1) found a sealed, metal
enclosed filter rated at 3A, about the same size as the original, which 
has an integrated IEC connector, 2) relocated the bathtub capacitor to
make room, 3) made an aluminum adapter plate to match up the 4 holes 
in the R-390A (old filter and relocated bathtub capacitor) to the new
filter, 4) since the receptacle is now recessed, shaved a little plastic 
off the cord end to allow complete insertion.

Works great, no additional holes, reversible, no more tripped GFI,
no more "tingle".

I wonder if anyone has any opinions on using one of those IEC-type
connectors 
on the back of an R-390A radio for a line-cord input? I have one R-390A
that 
someone had modified this way and really like it. A typical IEC 3-prong
plug 
will fit through the original mounting hole so the IEC connector can be 
mounted flush on the inside of the back panel without having to enlarge
the 
hole. This takes care of grounding the set also when the connector is 
properly bonded to the chassis. I know at least one mail-order house that
has 
the IEC input connectors with a Line-Filter built-in with a 3-AMP rating
for 
about 2-3 bucks each. It is really nice to be able to unplug the line
cord 
when moving or working on the set and not have the cord getting in the
way. 
Properly done the mod looks very nice. 73 Todd Roberts WD4NGG.
