Okay, mystery cap removed.

Now, since you own a 90 with dual 45 outputs (and I don't), you are saying that your 90 did not have the "mystery" cap in it? I just wanted to confirm that point. It actually made sense to me that there would be a plate bypass cap along the B+ line which feeds the plates of the RF, 1st det. and IF tubes. But if it isn't there, then it shouldn't be on the schematic...
