NOOOOOOOOOOOOO!!!!!!!!!!!! Don't let Wadia anywhere near it!!!!! Bring it to Steve at Great Northern. He just fixed my 850 so fast, it was on its way back to me by the time I called to check on its status! Wadia had my 830 for months, while they were deciding whether or not to stay in business. When I finally did get a hold of Wadia, I mentioned I had an 850, and they said if anything ever went wrong with the transport, they had no parts and wouldn't fix it. A year later, when the transport started making funny sounds, I called Steve, and he had the parts, no problem. Very fair price, too. (I don't remember what Wadia charged me to replace a humming transformer in my 830, but I do remember thinking it was an awful lot for a simple job, and I had to "negotiate" with them.) I can't say enough good things about Steve. He even listens to cool music (he wandered into a room I was in at CES with his own CDs).
