The trace on the backside of the board needs to be cut. When this mod is completed I was able to plug in a reverse power supply without damaging the unit. Normally the power adapter is center pin positive 9vdc 500ma. |

This first photo shows the location and orientation of the diode. I used a 1N4003 diode because that's what I had. Any 1N4001 or similar will work. I can help if anyone wants to perform this mod. narfman96 at yahoo dot com. |
