Anyone that has a qbert, if your machine has the sound board with the piggyback pcb on the sound board I would like to know the part number on the knocker coil.
According to gottlieb literature, the late build machines used the piggyback board which ran on lower voltages. I need to find out if they changed the knocker coil so it operated correctly. If I can get a part number of the coil it would be a huge help.
Here is a picture of the sound board that has the piggyback amp board installed.
