REPAIRING LIONEL'S RS-1 SOLID-STATE TRANSFORMER, P/N 12780...

[Anonymous]

Does anyone have any experience repairing the circuit card assembly in the Lionel RS-1 transformer? This transformer was produced 1990-1993. Lionel Trains, Inc. says they have no technical information other than the owner's manual.
Specifically, I'd like to find the schematic, wiring diagram, parts list, or exploded parts diagram.
Thanks for reading this.
