I just assembled a mini^3 and I think it failed both quiescent current check and rail splitter check.
The current I measured was ~18mA instead of ~25mA. I checked the soldering and it seems alright so I moved on.
But the rail splitter check definitely failed. The V+ V- gave ~8.7V while V- IG gave ~8.3V.
I have not turned it on yet. Can anyone give me some suggestion here?
