Note that the S-40A uses an entirely different arrangement of coils and
capacitors and has no equivalent to C62 in the S-40B.

So why is the S-40B equipped with C62? Maybe switch S1B in the S-85
exhibits a higher capacitance between the two rotary segments than does
S1B in the S-40B, making C62 unnecessary to achieve the desired coupling
capacitance in the S-85.

Although the parts numbers are the same, maybe Hallicrafters used a
different switch vendor for the S-85.

Knowing this would matter only if someone were restoring a receiver and
expected a part number for one type to represent the same exact part for
another type. And maybe that's the case. But I haven't thought about
that until now.
