Thinks Mike...I will likely patch in a resistor to provide the 6.3 v so the lamp will actually work. If I understand it correctly the heater string should draw 0.3 amps (based on tube data) so a 6.3 v drop with 0.3 amps would require a 21 ohm resistor. Sound right? A #46 bulb will draw 0.25 amps at 6v
