Pyramid PS-14KX problem

I was using my pyramid for 10 minutes yesterday when it went into protection mode. Now when I turn it on and the green normal lights up, but the minute I plug something in and draw current, it will go into protection mode again. I put my hand on the two 3055's and they are not hot. I took the cover off and there is no burning or smell. the minute i unplug from the unit it will go back to normal, then when I turn the unit off, the green normal light stays on for 3 to 4 seconds and then fades. Any suggestions? I also tested with my amp meter on several areas and it seems to be getting power through them where I tested.
