My tt was working fine until now. Now, it just plays for a couple of minutes, and then it slows down like someone pulled the power on it and stops! And it won't restart until I turn the power completely off and on again. This has never happened before until now. How the hell do I fix, assuming it can be fixed? If this thing dies... !

oh, that sounds horrible what kind of turntable is it? Is it modified in any way?

I would go to the nearest guitar center, if you have one, I live in canada so I just go to this store called Moog, anyways go there bring your decks and ask them if they can try it out and see whats the problem.... I doubt you cant fix it yourself but i'm just saying if you have no idea what the problem is go and see ..
