I’ve had a *ton* of requests for copies of the Pub Time Darts manual and schematics that were sent to me by Merit. They do not support the game any longer, but they sent me a free set of the documentation. They also emailed a nice description on how to modify the boards to not need their special power board. Here is a copy of our email conversation:
My Email Request:
I have a Merit Pub Time Darts machine that is missing the power supply that supplies 14 and 9 Volts. Do you have one available? I’ve checked all of my other sources and have not found any parts for it. The model I have is the normal one without the CRT display, but it has the cricket kit installed.
The power supply for your game is no longer available. It is possible to replace the power supply with a switching power supply. It will require some modifications to the logic board. You will need a switching power supply rated at +5 volts @ 11 amps, +12 volts @ 2 amps. The current rating can be higher. You will connect the +12 volt output to the +14 volt wires in the harness. The +5 volt regulator on the logic board should be removed and the +5 volt output from the power supply will be connected to the +5 volt pad the regulator was soldered to.
This should supply the proper voltages to have your game work again.

Hope that conversation helps you. Of course, try this at your own risk. It helped me! The schematics show a section on the right of page one where the modification is to be made.
