I love the mail bag.
I have built a Microcontroller based regulator for incandescent bulbs in the 1-2 kW range. I want to send you one for your mailbag. I just have to get around to sending it.
A link to it, and development can be found

So I figure you might like one to test, fiddle, blow up. I've only been able to test at 50V (battery) input and 15V/30A RMS output.
