Finished it and after finding out I had both voltage regulators (7815, 7915)reversed I need to see why it does not work.

1. Since I had the VRs reversed should I expect damage to them or any downstream components. They got hot when reversed and still get hot when inserted properly.
2. The AC power source measures about 12 volts and not 9.
3. When measuring voltages, since I'm not a circuits expert, should the meter be set on AC or DC voltage? The board has +/- 15v testpoints. AC or DC?
Thanks!
