If the resistors go to the gates of the power supply FETs, the FETs are probably shorted. Measure the resistance between the gate and the drain (no power applied to the amp). It should be at least several thousand ohms.
If you can take high res photos, send them to my email address:

You have to check what could cause these resistors to be burnt. It might be because of caps or IC. Unfortunately, I don't have this type of circuit board. If you cannot find it, try with the same value of resistors that are placed close to these fault resisters.

You have something in short circuit in power supply pattern, so filter coils are burnt. It may be voltage regulator, or regulating transistor, electrolytic capacitor or even shorted diode at pwr. input serving to protect in case of inverse polarity applied. Check all for short. Was it reverse polarity or overvoltage occured?
