Have some odd variations from schematic

I picked up an airline 94BR-1535a and have recapped it. I also replaced missing tubes. AM works fine but FM is just static. I started digging deeper and noticed a couple of irregularities. T7 has a small cap bridging one side and what looks like a dog bone resistor bridging the other side. Can't find this on the diagram. Anyway, the resistor tests open. Was this some repair or factory adjustment? Also, from T9, there's a 3.3m resistor where c22 is supposed to be. Did someone mistake a color coded cap for a resistor? I've reinstated c22 and AM seems to work better. I've also ordered new FM tube 6au6 for kicks.
