It may not be necessary, and the 10W resistors tend to be larger and may fit more neatly on the other side of the board, but if you're ordering parts, I'd order one or two replacements even just to have on hand Or if you are handy, play the amp for a while (let it get hot as ususal), then turn it off, drain the voltage on the caps, and measure the resitors resistance in circuit while still warm but without voltage on it...see how close it is to spec. That may be a good indicator on how important it may be. Then again, it is another place, on a PCB amp, that if the old component falters, you'll get arcing and such...you *could* just replace it.
