Hopefully you can see it well enough here, otherwise pm me and I can email a full size scan.

Hey, you're on to something... I found an "extra" capacitor (same value) and a couple resistors wired to the vertical output tube socket on my set. Not being in the schematic I removed them, but I took pictures of them and sketched the schematic of the extra parts before removal. I saved the parts, in case this may have been some form of field fix that came out after my manuals were written...
As an aside, I've heard quite a few interesting stories about the guy who used to service this TV for my grandparents. My mom recalled that when he would come over, that supposedly was the only time my grandmother would make fudge...
My uncle also remembered when he bought his first Hi-Fi setup. George (our repairman) came by to look at it and clipped out a few parts, telling my uncle, "There. That will sound much better. Those parts are more for wattage than fidelity." Sure enough, the set was still plenty loud, but the sound was more true.
