Another option is to disconnect the plate and cathode leads from the socket and add terminal strips for the 1N4007 (I like the 7s better) diodes so the above chassis appearance remains the same and you still have a glowing rectifier tube.

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.
