I have both the Sam's and Hallicrafters service information for my S-40A,
and the dial cord diagram on each was wrong for my radio. I had to cross
the dial cord at the bandspread cap to get the tuning knob, the bandspread
dial and tuning knob to get into agreement. I say it was incorrect for my
radio, because it looked like the diagram would have been correct if the
bandspread dial were calibrated in the opposite direction. Anyway, I can be
more specific if the original poster runs into the same problem.
=============================================

I had to cross the cords in my S-40A too. The instructions in the
manual were wrong for my radio. In my S-40A, the bandspread capacitor
plates turn clockwise to increase capacity, in my S-40B the plates
turn counterclockwise for increasing capacity. So the S-40A and S-40B
are reversed! I don't have a S-40 so I don't know where it fits in.
Just string the cord so the bandspread capacitor increases capacity as
the dial moves from 0 towards 100.

If the BS dial just reads 0--100, you can string it either way.
On my SX-11 (a real antique!), the dial reads 100 at *minimum* capacitance, the
top of the band. My Super-Pro 400 seems to be the same way.

True, the antique 3-dial BC sets used 100 for fully meshed capacitors, and 0
for wide open. So, whatever floats your boat (anchor).

Since the SX-25 has calibrated bandspread bands, I know that one was backwards!

The bandspread dial also reads "set to zero for normal tuning" twice. There
are also some arrows indicating which way zero is.

OK. So that tells you which way is the right way, for that radio.
Hallicrafters seemed to change their minds a few times. I just checked, and
the SX-42 is indeed 0 at the top of each band, but the SX-25 is 100 at the top.
