I pulled all the atlas electronics from a Hi nose GP35 and transferred the PS3 electronics and 2 rail trucks from a spare MTH GP35 into the Atlas. So far going very well..i was very surprised the MTH premier trucks fit the cast Atlas chassis.
Here is my ?. The PS3 2 inch 4 ohm 4 watt speaker will not fit the oval 8 ohm 1 watt atlas speaker in the fuel tank. Any harm in using the existing Atlas speaker with PS3?
