Does anyone know what motherboard would be a good substitute for the 691-PCB1-03B motherboard? Lionel does not list this part number at all, I guess because it was made in 1999. It is from a Phantom II engine, 6-11859. Mine contains a manufacturing defect where two of the three 24 pin headers are soldered in place such that they tilt the RS Audio and RS Power boards upward and the boards hit the top of the shell before it is fully seated.
Thanks! George
