Where did you come up with this spec.
Thorens site says, "The measured values for wow and flutter, rumble and
signal-to-noise ratio are actually so low and insignificant that we decided not
to publish them."

My troll detector has a slight buzz.
Fear not.
I don't know why they would put that statement on that page. That same
verbage for spec' is used on their top line models though.
This is the spec/manual;

I noticed the next step up (TD190?) is rated +/- .07% or so.
Anyway, first thing I'd do is check the belt, make sure there isn't a twist in
it.
Then check the auto stop mechanism. Make sure it isn't hanging up and
dragging.
I did that again.
Now, .12% equals 4 cents(?), can I hear it? I didn't know so I had to
try it. If my Lex pitch shift is what it says it is, yes. -not too
hard to hear up around 1k. That's a bad sign in both ways as on one
hand I suspect this thing is doing worse than that (a defect), and if
they got it down to spec would it even cut it then.
