I bought a TD146 in, I believe, 1984 and used it for about 25 years. The TP-11 MkII tonearm was a bit different than I was used to seeing on Thorens tables. Instead of a removable headshell, the tonearm on the 146 had a removable wand (TP-63) with integrated headshell and the anti-skating was adjusted by moving a string-suspended weight, instead of a knob-selected setting.
The 146 had an auto-lift and shut-off mechanism which utilized an optical sensor that sensed the faster arm movement in the lead-out groove. This generally worked well unless the record had been stamped off-center. I had two LP's and quite a few of the large-hole 45 RPM singles that were stamped enough off-center that the arm would lift before the last song was finished.
It's likely that there was an adjustment that could have corrected this but it occurred so seldom that I lived with it.
