Hello All
Here is a conundrum for you. The 2 DCC decoders listed in the title above are 5 amp large scale decoders with integrated sound. I have used both of them and they work well. They are identical in appearance and I would bet that the circuitry is the same. The 1818 makes diesel sounds and 1819 makes steam sounds. You can readily get the 1818, but the 1819 is unavailable and I would like to find a couple. I have no idea why the manufacturer discontinued them. Seems kind of strange.
