D200 have O/C protect, rail voltage is /-75V max. and output power 200W on 8 ohms load. I will share schematic and pcb after test.
I don't know if anybody has mentioned this already, but why not just use a IRS2092? Is basically have all built in - analogue audio preamp, pwm gen, mosfet driver, protection and more. B&W use it in their high end HT sub's.
Here is the link to the PDF: http://www.irf.com/product-info/datasheets/data/irs2092.pdf
They have a few reference designs on their website, complete with PCB files

With +/-30 vdc use 1k/2W instead 2k2/2W, IRF640 instead IRFB4227 and TIP122 instead BD241C.

IR2110 is easy available and not expensive. With 74AC00 power on mute and O/C protect is add. With BD241C no need for extra 12V bias suply...
thanks to sir apex
thanks sir apex
nothing else change need ?
if i change irf mosfet then it is not too need the gate resistor ?
i have tip 31 not tip122.
is this good ?
i have T106-2 too.
thanks sir apex

You can use TIP31 but replace 10k resistor with 3k3 (conected to base TIP31 and 12V zener). D200 run at 450kHz.
Been waiting for a Diy friendly ClassD, I can't wait till January when I'll get some time to build it
Regards
There is many diy frendly build in thread http://www.diyaudio.com/forums/class-d/166214-ucd-25-watts-1200-watts-using-2-mosfets-302.html , this is my version of SODA
Regards
Change O/C options with diferent value of 0R1/5W resistor, for example use 0.05R/5W for 12A.
i dont have 74hc00 , irf640 , tl081 , cap 224-250v , res 510 ohm 1% now.
i buy that tomro.
very thanks sir apex

An externally hosted image should be here but it was not working when we last tested it.
