Thanks for the picture. However, T sent a PSU file of this to me yesterday, and the resistor values were different. Your 5 ohm was given as 1 ohm, and the 3 ohm was a 2 ohm. Putting the above values (5 and 3) in PSU, I get a voltage across the load (tube's heater) of 8.5V. If, however, 2 and 1 ohm resistors are put in, the voltage across the tube's heater is right at 12.6V.
