Now I need to figure out what polarity the charger jack has. I'm hoping it's the standard tip is positive?


Center-positive (bother to check the Mini³ website?)

See the Parts list section for the wallwart. Also if you read the schematic it should be apparent which polarity is used for what.

Replaced my opamps with a new ARDZ from Digi-key and OPA690 from amb, all good now. Had to try a few times at reflowing U5 pin 7 to get normal DC offset in the left channel. Man, this thing sounds nice.
