I don't see any evidence of water damage. Were the resistors burned or corroded?

Were the original resistors burned (black/brown coloring on body of resistor or board) or just corroded (gray, green or orange)?

Black. That's what I wanted to know. They were burned.

With the amp powered up, what is the DC voltage on each of the 3 legs of the transistors that are connected to the resistors that you replaced. Place the black meter probe on the amplifier's ground terminal. Place the red meter probe on the point where you need to measure the voltage.

If all of the transistors for those 6 resistors have essentially the same voltage, you only need to post the voltage for the 3 legs of one transistor.
