Good day guys, does anyone know the correct values for the two gate resistors on this board Mtx Thunder 204? the originals were replaced with two 68ohms value based on previous repairs and the board is burnt so I'm unable to give component label info. The power fets are two 75339P fets. I've added a pic of the board.

This isn't a definitive answer but...
68 ohms is likely OK. Some of the larger amps driving 4 FETs use 61.9 ohm resistors.
The amps with the driver transformers are less critical than amps with a direct drive circuit.
