I removed the factory sound boards from an LGB 2019s mogul when I converted to onboard battery. Boards were fully functional at the time of removal (today). If someone has a 2019s mogul or similar with the early sound that has failed, $25 plus shipping to your door. I will include the internal headlight control board that goes inside the mogul’s boiler as well, the trigger module that mounts on the front tender truck and the double stacked circuit boards from inside the tender. I reused the flickering fire box board. (PENDING SALE) Mike
