I have a Massoth 2-6-0 mogul sound decoder I got for an engine I nolonger have. I would like to sell/swap it for an Alco sound system for my Aristo FA-1. Doesnt have to be the newest stuff from Phoenix, an older one from Dallee or Phoenix would be fine, even the self contained LGB sound in a black box would work, euro diesel or american diesel. Asking $125 cash or swap. Thanks. Mike
