Default K6- Switching power supply

I wonder if any one worked and succeeded into the K6 switching power supply,

www-a-and-t-labs.com


I built this supply from scratch, but the mosfets burns at 3 amp draw .
I dont know why!?


I connected my amplifier, put some music at high volume 4 Ohm load.

30 seconds playing. watching the multimeter, at 3 amps , the fuses blown, check mosfets, they are gone!!

they get very hot at low current draw.


Any comments?

There are several bad reports on this particular power supply. Do a search and you can follow the threads.
