Hey- I built this circuit last winter and spent quite a bit of time tweeking it for the 45 tube but with a 3k primary. I currently use the 2A3 circuit you posted. I haven't decided what 5k primary to go with for the 45.
Looking at my notes here are some of my values for the 45 tube:
no R3.
R4= 6500
R5= 90.9k
R7= 25k
I= 31mA
Plate Diss= 8.4W
T2= 383-0-383V.
