I'm not very knowledgeable about Thorens TTs. With Vintage turntables, spindle bearing and tonearm bearings condition can be key. Spindle bearing should be silent. Tonearm model affects performance and value. That's a very good model TT. Just make sure tonearm floats when counterweight is balanced and anti skate is off. No sticky spots vertically or horizontally. See some Utube videos. Theres a Thorens thread within the turntables thread. Assume may have to replace the Black stylus
Officially, questions of value are supposed to be asked in the Dollars and Sense thread.
Thanks for the tips on turntables. I didn't realize there was a special thread for "questions of value". That's interesting.
