Managed to locate another tech recommended by Yamaha-I have 2 non-working and one working DTXtreme iis, very happy with how the DTXtreme sounds now that I finally have one that works. I also now disconnected my older DTX 2.0 module I had been using for quite awhile. I am debating selling it with a few extra TP 65 pads I have. But will be hard to part with. If I can get the other 2 repaired, I will post the DTX 2.0 for sale on eBay (maybe!) Why Yamaha discontinued the DTXtreme modules is beyond me, Like their QY modules, these still are very powerful music-making tools and after studying all the other modules, these still seem to be a better bet to me. The nice thing about all the Yamahas is that they have kept for the most part, the same concepts for settings, programming etc. as on my original DTX 2.0, very helpful.
