To Maynard and Don: I have gone over the schematics of the S-85 and
S-40B and after staring at them for quite a while now can't make sense
of it. I am missing something, what? The two are pretty much identical.
Both are confusing because, for one thing, the coils are not in the
order of the bands. I am just not seeing something or have become cross
eyed. I will keep at it because I just need to know.
The two low frequency bands appear not to use transformers or else
the primary is coupled from the other coils. Eventually, the penny will
drop and I will get it.

Providing only two primary windings in the S-40B as opposed to 4 such
windings in the S-40A may have saved money, but it might also have made
the receiver more useful to at least some owners.
