That's an interesting circuit! They also seem to use the other heater section to do something with V1B grid, presumably to sweep (wobble) the output frequency in sync with the scope trace drive. Perhaps the two heater voltages have to be in opposite phase to put LF at the left end of the sweep? Maybe someone whose circuit analysis is less rusty than mine could illuminate here?

If you can find a TX with two separate 6.3V windings, they could always be connected in this fashion by using the start of one connected to the finish of the other as the centre tap.

If my guess is right and you could live with a reversed wobbulator display, I should think you could use just the one winding.

A 150mA HT secondary sounds rather generous- that valve set shouldn't take much more than about 60mA HT altogether.
