Hi everyone. I have an Aopen AX6BC motherboard that I'd like to revive.
I've identified 3 missing components on the motherboard and I was wondering if anyone here has this mobo and if possible could provide the values.
I have donor boards so I'm sure I'll find what I need.
The missing components are:
R309
R310
C250

I have marked the location on the motherboard where they're located.
If no one has the exact values, I'm willing to take best educated guess on them.
Many thanks.
