I hope I have not screwed up on purchasing this Thorens
TD170. It's rated =/- .12% DIN but I can hear the pitch
instability. At this point I'm trying to sort out if the problem is
simply a defect and warranty issue -or par' for this
thing. Wayne Smith


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.

Anyway, first thing I'd do is check the belt, make sure
there isn't a twist in it.

Actually, there is no such thing as a regular turntable belt with a twist in
it. It would have to have two twists.

Then check the auto stop mechanism. Make sure it isn't
hanging up and dragging.

The actual auto-stop mechanism is effectively disconnected from the tone arm
until the tone arm is near the center of its travel. I've never ever seen a
auto-stop mechanism cause flutter or wow while playing the outer grooves of
a LP.
