I don't have that exact schematic at my fingertips, but looking through a Tekfax I have here at home (my Sams are at my work location) yields differences - On one chassis, (12BC50) there is a 470 ohm 1/2W resistor tied to pin 3 and 11 on the 6LB6 on one end and to a yoke plug interlock on the other. Through the interlock, it ultimately goes to a 390V source.
On yet another set, the same two pins of the 6LB6 are tied to a 3.3K 7W resistor, and then to a 270V source.
If it was a 470 ohm 1/2W (yellow violet brown color code), it would darken the yellow band to orange....
Hope this helps,
