Default PowerAcoustic 3000db

I have been working on this amp ;for several days I have rebuilt entire driver card, removed all output fets and the powersupply is in working order. My problem is that the 220ohm resistor locasted in position c191 keeps burning. The amp turns on and doesn't go into protection,;the resisitor just keeps burning. I have verified that I have on shorted junction at the fet outputs. And the 4580ic in the driver card is socketed with it in the circuit or out the 220ohm still burns. I have no schems. Any and all help would be wonderful.
