Hi Sam,

It seems that buzzer pair is wired for the 6th pickup key on the 2nd row as the lamp comes on when it buzzes. This happens on the 2nd amp connector. I'm hoping that I can move the buzzer pair on the second amp connector so I can get it to work or figure out what connector number on the main board so I can connect the buzzer.

Is it normal for the line lamp to stay lit when you hang up the receiver until you push the clear button by the amber key?
