ACE,
Did you ever get to root cause? If not, where is the little guy now?
Can one even buy a CW-40 anymore?
I ask because I'm in the market for two things
1. low-cost transformers for accessories on my layout (Conventionally controlled with blocking and automation via relays)
2. a busted CW-40 or CW-80 for a special project I've had in my head for a while. All I need is the 120-18 step down transformer out of one. I know I can get this type of transformer elsewhere, but I don't want to pay lighting showroom prices!
