NE2 bulbs need 75-90v db supply to run. If your to use them use NE2H
as they are brighter.

 Actually in my PDP-8/x the use of white LEDs seems like
it will be a win. 

Almost...  White leds are biased toward blue white and incandesent lamps
were white biased toward red.  Also with incandesant the color of the lens
cap was a factor.  for examaple it could be red, amber, green even blue.
