I have what looks like a ‘current doubler’ from Voodoo lab, and connecting this to a center positive cord. (See photo) First, is this the correct, safe way to power this unit from the Ojai?

Yes, as long as this is a current doubler cable this is the exact configuration needed to power the H90.

I can set the output on the Ojai to either 12V or 9V. Whats the minimum amperage necessary for either setting? If I can get the necessary amperage from either voltage, which voltage is recommended?

800mA @ 9V
600 mA @ 12V

I would go the 12V route because you’d be well within the tolerances of the H90 at that voltage.
