my cmoy in a mint tin is working great, except for one little quirk: when i use power from the dc jack, the sound is gone. when i wiggle it around, it comes back. i pulled out my trusty voltmeter and found that when the sound is there, one rail measures 8.3V and the other 7.6V (is this normal, btw? seems pretty unbalanced to me...). however, when the sound goes out, the virtual ground apparently is collapsed, and all 16V was concentrated on one rail. how did this happen, and how do i fix this? how come wiggling the jack/plug around helped?
