I recently bought an MTH 0-8-0 steam engine with tender (#30-1112LP), Chicago Northwestern line. The engine is in great shape, runs smoothly forward, neutral and back, smokes like it's new. However, the tender sound hardware has been modified and produces no sound. There's no volume control potentiometer, there's no 9V battery clip to power the board. There's a board and speaker there, yes, but it's not doing anything. No horn, whistle, or bell sounds, no engine sounds and no rail or yard sounds. So I'm looking for an MTH tender for sale by itself if anyone has one. Maybe I can just take my CNW shell and switch it with the shell of another tender. Or recommendations where I can buy a new hardware set to replace whatever has been removed. I don't need a sound upgrade, but just want to get sound restored to it. thanks all.
