In this video I cover the conversion process of a HO MTH DM&IR Yellowstone from its factory installed PS3 decoder system to a Soundtraxx Blunami BLU2200 decoder.
With this conversion, you do lose the smoke feature as Soundtraxx cannot operate a synchronized smoke unit. This a major downfall for converting steam engines to Soundtraxx as they are now the only decoder company that cannot operate a smoke unit. But hopefully one day they will make one that can run the smoke unit. Otherwise this conversion is 100% worth it.
The items that were used in this conversation were a BLU2200 Steam-2, Current Keeper 2, DBX-9000 harness, 1k ohm resistors, and various LEDs.
This conversion was done for my local Railroad Museum I volunteer at, the Northern Minnesota Railroad Heritage Association. Most of the parts were bought by the museum and I volunteered my time and a couple LEDs and resistors to do the conversion.
