Hello, I've built a Mini 3 portable amp but it does not pass the rail splitter check. To measure the voltages I connect a charged 9V battery and place the black probe on V- and the red probe on V+ just as the AMB webpage describes. I get 8Volts, ok so far. The problem comes when I measure voltage between V- and IG, then I get 4 volts BUT it drops to 0.13 Volts in a minute or so. This is not a normal behaviour, is it? Quiescent current is 25 mA, so I assume opamps are ok.
