But replacing the two line to ground capacitors C27 .02 mfd, 600v and
C26, 400v.1 mfd (it says mfo on the schematic, but that must be a
misprint). I figure these are the line to ground capacitors, since they
are the only two on the schematic going from both lines to ground.

I plan to replace
C26 & C27 with Y2 safety capacitors. But cannot seem to find any at 400
and 600 volts. The ones I can find are just 250 volts.
I must be missing something about the solution.

I really don't want to put in an isolation transformer.

Any help you can give me on replacing C26 and C27 will be most
appreciated.

Also I have about 45 feet of space in my two story home's attic. Any
recommendations on a good DX antenna?

If those 250 volt replacement caps are sold as "safety caps", they
should be excellent. They are rated to handle any normal surges from
the AC power line.

If your antenna must be inside the attic, just run a wire all the way
from one end to the other and bring one end down to your S-38.

Others may suggest a type of loop antenna. Thousands of S-38's have
been used sucessfully with single wire antennas.

Good DXing.
