Default Polk Audio psw300 schematic?

Hi,

I'm servicing this sub in which the amplifier has failed (and cooked the woofer, or the other way around...)
Beside the shorted dual output/power transistor I found also a 1w(?) resistor that is burned and reads open.
Its color stripes are completely darkened so I can't identify the value. It is labeled R16 on the PCB.

I can't find any reference schematics for this amp on line so would be most thankful if any one could help me identify this R16.

Thanks in advance,
N.Webber
