I just received an RX14 main board from Mato and am curious about the 4 resistors on the bottom of the board. I have looked at several RX14 boards on the forum and none of them have these resitors. Anyone else have a main board like this with these resitors and know why they are there here is a picture of the resistors

Got one from UK recently and came also with those 4 resistors. Must be factory installed, then.

Them 4 resisters look like the once's that were on the front of the rx-14 in the same spot but on the top .

thanks

my board still has the resistors on top as well

could be to help lower the resistance in that area .

thanks

Are they all ganged to the same spot? They look kinda like pull-up/down resistors. These would be used to ensure that the FETs' gates are biased correctly, and prevent them from floating, which can damage the FETs. Perhaps this explains some of the spontaneous RX14 board blowups?

Thanks for the info
