I heard about this earlier, when I first encountered problems with band
4 and I took this peculiarity into account when I did the alignments.

Just in case you haven't checked it.... Be sure the the bandspread cap rotor
plates are fully out while doing the alignment.

I bought an S-40B on ebay a couple years ago. I'm almost inspired to go to
work on it.

Good luck
