  We have specifically designed it so that it is fully adjustable to use on platters with no mat to platters with 5 mm thick mats. It also does not scuff the record label as it is tightened up.

The Record Clamp can be used to safely lift the bearing and platter off the spindle without fear of the platter and bearing dropping and smashing the jewel.

  

Operating guide: - 

Please read the following instructions carefully before fitting the Record Clamp, we can not accept any liability for any damage caused to the turntable or associated equipment. If you have any queries about fitting the Record Clamp then please contact us before fitting it.

  1. Before you place the Clamping Knob on the turn table, slacken the small grub screw in the side of the Setting Ring with the Allen Key supplied.
  2. Then screw the Setting Ring down towards the base of the Clamping Knob.  
  3. Place the Clamping Knob over your vinyl record on the turntable platter, and screw the knurled Knob (this is the one with the white plastic insert in its base) into the top of the brass bearing by three or four full turns.
  4. Then, hold the base of the Clamping Knob gently and screw the Setting Ring up to the knurled Knob until it touches the white insert of the knurled Knob. 
  5. Next, unscrew the knurled knob 1/2 a turn.
  6. Again, turn the Setting Ring up so that it touches the knurled Knob again.
  7. Now tighten the small grub screw in the Setting Ring (just 'nip' the grub screw up, it should not be too tight).
  8. Finally, the knurled Knob can now be tightened down onto the Setting Ring so that the white plastic insert is pressing onto the Setting Ring, and as it does this it will clamp the vinyl disc to the platter (again, do not over tighten, it only needs to be nipped up). 
  9. Your Clamping Knob should now be set correctly, and the next time you use it, the Setting Ring should not need to be adjusted. All you should have to do is screw the knurled Knob down and it will clamp the vinyl to the platter.

If your Clamping Knob does not screw far enough into the brass spigot that the vinyl disc locates on, then send the Clamping Knob and the upper part of the PT bearing to us at True Point (UK) Ltd and we will drill and re-thread the brass spigot deeper. This will ensure the Clamping Knob works correctly with your turntable setup. We will do this free of charge. Unfortunately this may be necessary because we have found that the depth of the M3 tapped hole in the brass spigot does vary.

Also, if your PT bearing's brass spigot does not have an M3 tapped hole, send it to us and we will machine it to the correct depth for you free of charge.

 To remove the Clamping Knob

 1.      Gently hold the base of the Clamping knob lightly to stop the platter spinning, then unscrew the knob until the base lifts off label (see photo 3).

2.      Then steady the platter whilst unscrewing the knob completely.

3.      Carefully lift off the Clamping Knob.

We are also developing adjustable turntable feet with Sorbothane pads. The feet will will be similar in appearance to the clamping knob. More details coming soon.

Lookout for our 'Uni-Pivot' Tonearm, coming soon.
