Greetings all. I need assistance identifying a MTH O Gauge Lionel Corp Tinplate 263E PS3 engine circuit board. The MTH train number is 11-6070-1 (or similar, not sure if it’s the 2013 or 2018 edition). The circuit board in question is in the engine and drives the motor (or at least pass through), smoke unit, and lights. The MTH website doesn’t have a parts list. The MTH 2015 or 2017 Tinplate Parts Guide doesn’t list any PS3 parts. From previous repairs I suspect this may actually be a HO part. I need the MTH part number so I can order a replacement and finish this repair.
Background: I received this repair with a complaint of no movement or lights in the engine. The engine shell was already removed and the smoke unit had some work on it. I quickly saw that one of the chips on the engine board lost the magic smoke (hole burned in it). On power up the sound plays and the PS3 board responds to the DCS remote so I strongly believe the tender PS3 board is good. After removing the engine board I discovered U38 (unknown chip) was burned. On the reverse U109 (unknown chip) and Q169 (unknown transistor) was also burned.
Bonus question: I also need a replacement roller for the tender. I’m sure I can find part number myself but haven’t got that far.
Attached are photos showing the train and engine board I need a replacement for. Let me know if you need additional information for an ID.
