So your pitch slider feels like it's full of sand? Time to fix it. This instructable will demonstrate how to replace a worn out pitch slider on a Technics SL-1200/1210 turntable. It will also show how to adjust +6% pitch value if it has drifted or if the new slider has different properties than the original one. I've also added a new shading cloth as the one in my 1210 turned to dust when it was touched.
The most important thing is to remember to DISCONNECT THE TURNTABLE FROM MAINS POWER at all times before the platter is removed! This is both for your own safety and the fact that the motor can be damaged if it's accidentally turned on while the platter is removed.
I bought my new pitch slider from a shop on ebay.co.uk for around GBP 13 and the shading cloth was GBP 2.50 from the same place.
This will probably take an hour or so depending on how handy you are with the soldering iron and desoldering wick.
The information in this Instructable is information I've picked up from several different text based instructions on the net (Technics SL-1200Mk2/SL-1210Mk2 FAQ from hyperreal.org and several more I have not saved). I thought it would be a good idea to document it with pictures for you guys as I was replacing a slider anyhow.
Please note that you do this on your own risk. I've done all steps here several times without any problems. If you damage your turntable or get shocked or similar I am not responsible. If you don't think you are competent enough or your turntable is still under warranty, let a professional do this.
Step 1: Removing the platter
Disconnect the turntable from mains power before doing anything further.
Remove your pickup from the tone arm to prevent any damage to it.
Remove the slipmat and you will uncover the platter which you will see two holes in. Place your thumbs in these holes, grabbing the platter from the underside with the tips of your thumbs. Push with the other fingers on the outside of the platter. The platter will move a bit upwards and then you will think it's stuck, pull some more with your thumbs and the platter will then snap loose. Place the platter in a safe place where it will not be damaged or fall to the floor.
