Power LDO-regulator finished, finally :o)

I've finally finished and tested my Low-Drop-Out voltage regulator, intended for my Pass Class A amp.
Drop-out voltage at 1A is less than 400mV, and at 4A, it's less than 500mV.
Dynamic test, with a pulsed currentdraw at 10kHz, low level: 10mA, high level: 4,5A, showed no signs of instability. Outputvoltage only sagging @25mV when shifting from low to high level.

Can't wait to use it.

Yes, I have access to an electronic load :)
