Question about Thorens TD158 Turntable
The Thorens TD 145, and some other Thorens models, use an electronic circuit connected to an inductor on the bottom of the tonearm shaft to lift the tonearm and cut power to the drive motor.
This inductor/circuit senses the increased velocity of the stylus when it accelerates toward the center in the wider takeout grooves at the end of an LP.
First, there are several mechanical switch and inductor clearance adjustments to be made. Then there are some more complex potentiometer adjustments that control voltage differentials.
My auto stop does not work. What's the best place to start?
I'm pretty electronically capable, but need guidance when it comes to knowing exactly what parts to check, and what VOM settings to use as I check them.
Leo J. Nesuahecner The bottom of the tone arm shaft has a white plastic cup with a single screw in it. You need to remove a large square plastic cover also with a single screw to access the cup. This cup has a magnet in it. As the arm rotates to the end of the record this magnet trips a switch that pops the solenoid under the start stop lever. By loosening the screw on the white cup you can rotate the cup so the magnet hits it's switch sooner or later . It is touchy so prepare to to spend time fiddling with it. There is a small pointer on the cup you can use to grab with your fingernail to rotate the cup counter or clockwise. Hardest part is standing the table on end and operating all functions with the left hand and rotating the cup to various positions. Remember to gently tighten the screw after each adjustment or it will move when the tone arm is moved.

Where did you find the Thorens manual?
Is it the mkII one or simply for the TD-145?
