I’d imagine there is no technical issue with doing it live. The manual says you can make adjustments but it doesn’t say that construction is bad enough that the pots break in normal use. Unless you were ham-fisted, it is unfair to make you pay for the repair. I use a strobe disk and LED product you can find online.
Problem with Thorens TD-203 speed adjustment screws
My Thorens TD-203 was rotating around 2% too fast (33.9 RPM) a few months ago, so I tried to adjust the little adjustment screw on the bottom of the table. I wound up getting no speed change but apparently ruining the screw. I just brought it in to the store's service department because it's still under warranty and they said the potentiometer was broken and the motor has to be replaced. I saw some videos that showed the adjustment done "live"--with the platter rotating. I tried to adjust the screw with the power off and by tipping the table up. I later found some messages that said this adjustment is very tricky and breaking the potentiometer is common.
Is there any advice about this other than never attempt a speed adjustment? Do you have to do it in real time or can you turn the screw a little bit and measure RPM after that? I used an RPM app on my phone and that seemed to work OK.
