Just finalized my build, when i power up using a rig that connects to the card (using a card edge connector) I have the following issue: No CP4500 connected I have +- 15.6v , even with none of the opamps or line drivers inserted, only the voltage regulators, the voltages become unbalanced, the negative rail goes to almoat -20vdc and the positive goes to 9vdc. I have tripple checked all of it.
