Just a quick update on this restoration. Motors arrived and installed. Testing the game I noticed that the +12V that the topper draws is affecting the Pinsound board with a Rottendog Power Supply. After a LOT of testing with this unique configuration, we have found that it is easier to draw the 12V from the 18V flasher circuit off the Power Supply. So the 12VDC is not affected by the Pinsound board. The booster is available on the Pinsound site ;
