Those are all acceptable values. The heater voltage (5.56vDC) is a bit low, and it might be worthwhile to reduce the 1.2 ohm resistor (T6 to T9). You can install a parallel resistor of 3.3 or 3.9 ohms, 1 watt minimum rating, and see if that does not get the voltage closer to 6.0 volts. You can do this with clipleads and a selection of resistors until you are sure you have the desired voltage. The voltage should be in the range 5.7 to 6.3 volts; I intended 6.0 volts +/-0.3v in the initial design. Increasing the heater voltage will bring the plate voltage down slightly.
Finally I put a 3.3ohm resistor as you recomended and the heater voltage goes to 5.98V, I hope this will be enough.Next step is to connect the Seduction and try to see if it is ok...Thanks for suggestions to all.
