Kinda.

I finished assembly of the low freq power amp. This is a ~40Khz, reduced voltage version of what I want for the final supply.

And it works, but the disable line is backwards, it turns on both the drive transistors which shorts out the supply, oops. otherwise, less giving it a full load test, its working.

If your wondering, the big green resistor is a part of a snubber circuit.

The control circuit works well (less the disable, which, for now, I may just label 'self destruct') I have to back off the max drive duty as a slight delay in the transistors turning off causes them to buck heads just a bit.

I'll work on connecting it to the regulator board and the current sense to see if I can get a power suppply out of it.
