The schematic below from an 84 shows a CT (5) on the filament windings of the power transformer to the CT (8) of the 80 plate windings.
The transformer is a 32-7180, also used in a 37-84, which looks like the same chassis, doesn't have that CT. I took the transformer apart, and there is no evidence of there ever being a CT on those windings.
And if you compare the 1934 84 to the 1937 84, the only difference is that CT, AND the .015 cap #32 is not there.
