Well this is what happened. I have had this amp for about a year and its worked fine but i thought i would be different and i changed the shift phase knob on it from the end it was on to the other end b/c i thought it would allow for the subsonic filter to shut off for lower resonance but i was wrong. I believe it ended up blowing 2 cubes in my amp and now i need to get i repaired but i dont know where or how and even if i can repair it. It was a great amp and id like to keep it. Is there anyone out there that can help or might even know what i did really to make it blow? Help would be very appreciated. Thanks in advance.

Clipping the phase switch would not cause it to blow unless something were internally wrong in the amp itself. As for a repair, contact Sergey at K&B audio. He can fix pretty much anything unless the board is damaged beyond repair.
