thats a bit on the low side, but you need to find out what the cathodes are, those are directly coupled to the video out tube. You want approx 100v difference in the cathodes to G1 voltage (cathode should be higher).
the greater the difference the more cut off the tube will be (darker). It does not take a lot of change to go from dark to bright.
