power supply to separate box

[TiCatFan]

I have completed building the power supply. Decided to power it up and check out the voltages. Used the power limiting safety socket, rechecked after on bypass. I think it all checks out good except for the AUX supply. I get +12 and -20. Everything seems balanced till it comes out the voltage regulators. Should I replace the 7912 or does this indicate other possible problems. If I had a 7912 kicking around I would just replace it, but I don't. Thanks ....
