I've got some Railking units I've pull out of storage for the first time in a decade or so to run on my Christmas layout. I have 3 Railking units that are horn/whistle only. Two of the three are quite loud, and just how I remember them. My SW9, however, is quiet and tinny. It's slightly louder when in neutral than when it's running. I took it apart and inspected the speaker, which looked fine. I didn't see any volume control on any of these horn/whistle only units. I rarely ran my SW9 in the past, so I don't know if it's always been like that, but it sure seems like it was just as loud as the others at one time.
I did inspect the capacitors, but non looked compromised from the outside. I know there were a number of issues with capacitors used in all kinds of electronics from the early 00's, and I guess it's possible one or more has had an internal failure. However, other than volume, the engine runs fine and DCRU work just fine as well.
Any other ideas on what it could be?
