I don't have a Tsunami-equiped Shay but before I bought my non-sound 3-truck-er I do remember reading a bit about problems with the sound shutting down over about 18V. One of the solutions was to fit series of diodes in the power feed to the decoder to reduce the voltage it sees compared to the actual track voltage.

Maybe try a google search on the subject?

Agree with all what has been said - the factory-equipped sound that comes with the Bachmann 3-Truck Shay does not like voltages of 18volts and shuts down when this happens.

I went the whole hog and had the innards of mine ripped out and replaced by a Massoth decoder and Pheonix sound system - expensive but well worth the effort.....

Don't suppose you kept the original Tsunami board did you Keith?
