[Hallicrafters] SX-117 disaster

[T David Cohen]

Jeff,

I've got a junk SX-117 -- let me know what needs to be replaced and maybe I
can help.

Good luck!

Thanks to all the fast responses.  I've drowned my grief a bit, and I did
some disassembly.  The Antenna coil surely does look like it got toasted.
I've included an image on my webserver:

In looking at it, it looks as if the coil form actually deformed
(inside) so that the slug won't move past a certain point.  I don't see any
damage to rotary switches or other components.  The 6DC6s test OK, but I
don't have any replacements in my stock to try a different one.

Anyone have any advice on the coil (or a spare you can part with?)
