Your voltage table shows 138V on V9 (pin 6) screen and 58V on V9 (pin 5) plate. A difference of 80V, most would be dropped across the 8.2K R36, that gives a plate current of nearly 10 ma. which could be. The listed drop should be 15V, but that can be effected by the contrast control. If L9 or L10 has a higher resistance then some of the voltage drop will across them and the current would be lower.
Don't worry about R35, the lower coil resistance will make that value unimportant in comparison.
Things could also be wired wrong.
