[Heathkit] SB-313, Lack of Sensitivity

[W8BYA]

New member here.  I have an SB-313 that I put together as a punk in the late 70's, and since day one, it has always had reduced sensitivity on one of the bands, I think it's the 25m band (maybe 31m).  I will be taking it off the shelf and firing it up this weekend to confirm the band.  All the other bands are hot as can be but that one band was always significantly "quieter" than all the others.  I have been through the alignment a dozen times over the last 40 years and thought I did a pretty good job verifying that the right parts were put in the right places.  Was just wondering if anyone with that receiver ever noticed the same issue or maybe even has a good place to start looking.  Tnx.
