Actually, if you want to pursue this further, we should be able to calculate the correct resistance values, and it might work out that only the larger three (component side of board) resistors need changing.

To do this, we need to know what resistance values the three tiny ones (copper side of board) have, and similarly for the three larger (component side) resistors. And measure the voltage input into the larger resistors from the chip that controls them.

It might work out nicely, or not.

Edit: Background: each pair of resistors for each transistor, form a simple voltage-divider circuit, scaling the output from the control chip into a voltage appropriate for controlling the transistor. The voltage we need is whatever is appropriate to achieve the correct Gate-Source differential for the transistor. We don't know that value (no datasheet), but we can figure it out from the measurements above and those already posted earlier.
