finally came across an article by VK3HZ that describes how to make a
microwave oven inverter PS work, as a stand alone supply.
the link is:

It's only regulated from the primary side. And you can make it put out
anything from 2000 to 4000 VDC. but at 1300 watts.

So all I have to do is load down the primary to fake out the regulator
into seeing 1300 watts, Or run class A.

The output or the input still has to be filtered

There's an opto coupler that has to see a 110hz square wave, according
to VK3HZ, that'll keep the supply running full tilt as long as there
is power supplied to the inverter.
