Lets see a pic of the power selection plug.
Other possibility is that the back of the board has the resistor hack done to raise the 5V.
BTW... You are in great hands with the help DA and PM have given you.

Something really simple is being overlooked. I don’t know what it is.
Correct transformer?
Correct power selection plugs?
Meter malfunction?

Quoted from Arcade:power selection plugs
I reviewed prior posts in this thread and found the pic of the "butterfly" configuration of your power select plug, which is correct.
There has to be a reason that the AC voltage is coming in higher than spec. As DumbAss calculated, when a bridge rectifier converts AC to DC, DC voltage = AC input * 1.414 minus the voltage drop across the diodes.

Nicely done all.
After correcting the pin locations, measure again before connecting to the power/driver board.
We don't want to damage the wiring, or worse, the transformer.
I've seen J101 installed one pin off, which creates a dead short on the transformer secondary. Melting, and eventually smoke ensues.

Make sure that all of the connectors that are supposed to be there at J116/J117/J118 are there and that the 5/12/G wires that are supposed to be there are solid. Seems like an odd suggestion, I know. Let's be sure anyway.

You are getting to the point where it might be advisable to send the MOU and driver bird to a pro.

Quoted from Arcade:Game seems to boot up with only a single tone.
This part is normal. The sound board makes a single "bong" upon successful boot.
