It looks to me like the tube in the back has it's 0.68ohm resistor being fed from the 0.68ohm resistor on the first tube. Both 0.68ohm resistors should be fed from the blue wire which I assume comes from the transformer. So move that red wire from the front tube socket to the terminal strip where the front 0.68ohm is tieed to.
That said it should still work they way you have it, one tube however will have less heater power.
Did you test the 0.68ohm resistors?
The soldering of the two blue wires and the terminal strip could use some cleanup. It looks like a short waiting to happen.
