throwgncpr Posted July 19, 2012 Share Posted July 19, 2012 Really noticed this today with an album I listen to a lot. My Thorens TD-158 is turning slightly slow. I've had it less than a year. Anyone know if there is a way to modify it (this model has no fine-tuning for speed)? Quote Link to comment Share on other sites More sharing options...
rochambo Posted July 20, 2012 Share Posted July 20, 2012 It's not slighty slow. It just has "special needs". Quote Link to comment Share on other sites More sharing options...
throwgncpr Posted July 20, 2012 Author Share Posted July 20, 2012 lol, special needs indeed. I know it's an entry-level turntable, but it otherwise functions great and sounds good. I was hoping that there would be some way to adjust via some screws or something under the platter. Quote Link to comment Share on other sites More sharing options...
throwgncpr Posted July 21, 2012 Author Share Posted July 21, 2012 Well, Thorens put me in touch with someone who provided me with some useful information. There are screws on the bottom of the motor. You need to take out the assembly to access them. 33 1/3 RPM screw is marked with an "L", 45 RPM screw is marked with a "R". Turn screws clockwise to increase speed, counter-clockwise for slower speeds. NOTE: Adjustments are VERY sensitive. Only turn a hair at a time. It took some trial and error to get it right, but she sounds so much better now!! Quote Link to comment Share on other sites More sharing options...

mrnubnub Posted July 23, 2012 Share Posted July 23, 2012 Ooh that really sucks, manual speed regulation? I imagine it must be hell getting the correct speeds Quote Link to comment Share on other sites More sharing options...

Who's idea was it to place crucial controls (which can usually be found in a user-friendly fader at the top of almost any other turntable) under the housing of the chassis?

gabpower Posted August 2, 2012 Share Posted August 2, 2012 Thanks for sharing with pictures. I had an old turntable with speed problems (too fast). It turned out that it was the belt that got loose. Replaced it and speed was better. Quote Link to comment Share on other sites More sharing options...
joshua Posted August 13, 2012 Share Posted August 13, 2012 yeah 90% of the time it has to do with the belt. Quote Link to comment Share on other sites More sharing options...
