Just an update on where I am in replacing the AC line filter on this 
Amelco R-390a.  Lot's of good suggestions from the group.  Had a couple 
of offers of replacements - one from a list member, and one from Fair 
Radio.  Fair has them for $20.

However I decided to go with Bob, N0DGN's suggestion of using a IEC 
computer type filter with the cord socket built-in.  I searched my shop 
and found one that had a Sprague label on it.  It looked in good shape, 
so I made a little sheet metal adapter for it because I wanted to use 
the receiver's original hole layout.  It fit perfectly.

Now the receiver is back to life, at least on a variac.  I need to check 
that capacitor in the IF deck that feeds the mechanical filters, but 
can't find my bristol wrenches.  I have some ordered, so am waiting on 
them before I do much else.

Thanks for all the good advice.
