I have an Atlas O scale Conrail ALCo C-630 #6770 and the smoke unit is burned up. The thermistor is completely destroyed the resistor/heating element is burned and charred. Also, the PCB itself has had some of the coating burned off. Does anyone know where I can purchase a replacement board and wicking? Sadly TAS, the manufacture is out of buisness. Will the Atlas part # 6947 Smoke Unit work? It says for smoke unit repair and retrofits. I am willing to look into purchasing a loco with simi internals at train shows, so are there any models that have the close internals to my model? Do the C-425/425s have the same unit? Thanks in advance for any help.

Hi there. Most folks on this forum are in HO or smaller scales, so don't be surprized by the radio silence. I don't own a loco like yours, but if I were you, I would contact Atlas and ask. You may also try posting the question on the Atlas Rescue Forum, and the MR Classic Toy train Forum. Good luck!
