I sold this but it came back with no sound and shorting out the track. I found a melted power wire between the two rollers. Classic for a derailment. I think it probably had that when I had it, but in my limited running, it never shorted out to the frame.
I replaced the wire and I restored the sound with an Aux 1, #6 but the horn sounds a little raspy. I can quill it at the start of the whistle control and cause it to sound strong but if I just pull the control down, it gets and stays very raspy. The other sounds seem normal, talking and engine sounds including the shut down sounds.
I hesitate to spend $90 to try another sound card...so I'm wondering if there are any other possible causes.
