The resistor method works well save the heat generated. My approach now is to install some diodes and rectify the winding for DC.
Do you think you have enough current capacity on that particular secondary transformer section to install a simple bridge and filter capacitor to generate 2.8VDC? Maybe you can also install a light bulb in series with the input tube filaments to create a voltage divider? But then there are the issues with polluting the AC 6.3V with rectifier noise maybe, etc.
