Ok I have an important update.
I found three grommets from a defunct record player that with one washer each was able to be used to replace the rubber grommets for the tuning cap. I did realign the RF section after doing that.
With my particular Philco 118 using 1800pF in place of the 3000pF cap gets the dial as close to being properly calibrated as possible.
I was able to pick up some hams on the 7MHz ham band so the sensitivity seems to be there.
For now I will leave it as is.
What I need to do is see how good the sensitivity is using the original 3000pF cap.
Also if the dial is off by the same amount on most of the Philco 118s maybe someone could figure out how much it is off and create a new dial scale with the necessary corrections made to it. That way the dial will be correct and no one else will have to go through thinking their radio has a problem when it is simply just that the dial scale is off.
What I wonder is was the dial scale off like that on SW when the radios were new? To me it would seem like Philco wouldn't allow that sort of mistake to make it to production.
