I'd be bypassing the rectifiers and tie power to the regulator outputs if I end up using an external dc source/s. While it wouldn't break anything to pass DC in through the AC input, the circuit wouldn't work that way. This circuit uses bipolar rails and there are only a hot and neutral pin on that ac input.
There is no voltage doubler circuit inside. The ac is rectified, filtered and regulated. It is only missing sufficient filter capacitance to be adequate in my estimation but there is no room in the box for what it needs. Anything from somewhere around plus and minus 5 to 18VDC would make this circuit function well enough I'm guessing.
