It regulates at 4.07 volts and .0131 amps for the two LEDs. It doesn't even change within +.001 volt/+790 volts and only +.0001 amps/+790 volts. It varies from 10 volts-800 volts.

How it works?

Why under 10 volts is the output so unstable? Couldn't it remain stable down to 4.7 v

@wyoelk, do some reading on how transistors work. And then maybe linear regulators. Mostly because of the voltage drop at the junctions of BJTs, this regulator is going to need about 2V of overhead. That is, too get 4.07V at the output, you'll need a little more than a 6V input. The simplest one-transistor linear regulator will only need about .8V of overhead, but most need around 1.5V, sometimes more.

Thanks, I didn't realize they needed that much overhead in a regulator, you always help out
