The photo shows one coil, which should give you an idea as to the
general size and construction of the coil.

More photos.

Oh-oh. My Heathkit coils do not have ferrite or iron slugs. The Eico
710 coils apparently do. The coil on the left is obviously broken.

Free manual for the Eico 710:

I'm too lazy to find a DejaVu decompressor, but I expect there are
some instructions and diagrams of the coils in the manual.
