Thanks for that.

Any chance we could share the schematic on the Vortex Website?

Well, I checked out LM2390 and that appears to pretty robust.

don't know about 78xx, tho' :-)
Is that a kind of generic code?
...and what about diode specs?

Would be great if we could confidently give a range of psu's, including DC.
