This is the best idea for turning your all tube rig into a sort of hybrid with obvious pros' and few cons' that I know of. You get to keep the correct appearance and you will not have to worry about getting a (the right) resistor to go where the heater used to be. Not such a big deal in a parallel arrangement type heater string, but in a series circuit all voltages dropped MUST add up the the source voltage or there will be a problem. I'm not sure what tolerance there is in a real world situation, but mathematically, by the use of Ohm's Law it is spot on.
