There is a simple fix for the heater string. Someone here will have the formula, unfortunately, I am not one of them.

It involves the replacement of the resistance part of the line cord with a capacitor that will drop the mains from 240 down to 65V@50Hz.

As far has the HT (B+), you will have to computer the total current draw from the rectifier tube and add a resistor of the proper ohm value and power. This would have to go on the anode side of the rectifier, since those are not designed to operate from a 250V mains.
