Unlock the Pod Piston
The VTA can be unlocked with two set screws on the side – use only the stainless (Silver in Colour) locking screws to lock and unlock with the T handle provided. Turn each of the two sets screw counter clock wise ½ turn to unlock the pod. Please exercise caution and do not adjust the center lock Allen screw it locked in place and damage will occur.
Turn the glider knob clockwise to move higher, .015 per 360 degree turn in height which equals .086 degrees. Only move the tuning screw the polished stainless large knob) when unlocked and you can leave it unlock while playing and true on the fly adjustment without a hitch. Listen and adjust it is truly simple and safe to use while playing your valued LP’s; you will find the perfect height.
Please take some time and read Grahams Engineering TT Weights Tone Arm Sheet and Manuals in the Factory Box from Graham Engineering for rough VTA setting of the arm height.
The total adjustment in the Glider is .200 inches (5mm) which is equal to 1.145 degrees (10 inch arm) in Stylus rack angle (SRA) adjustment
One turn is equal to .086 Degrees in SRA, providing extreme control, never before realized in this type of SRA control. You can super tune the VTA while comfortably listening to the music until you find that sweet spot.
The pod is designed to move in the vertical position with .0015 piston clearance for the large 3.0 inches plus in diameter piston and cylinder. Aersoshell grease packing for cylinder wall damping and the base of the cylinder has 3/8 Aersoshell grease damping) to cylinder clearance but for absolute parallel position both screws MUST be tightened otherwise there will be a .010 angle error in the tone arm to base parallelism.
Tips on Using the Glider Pod
Move the handle at least one turn; this is only a small stylus movement although very precise. The angle of the style is preset to the best listening position and may be between 91.5 +/- .5 degree once set up at your home due to the levelling process.
The Glider Pod should provide the needed adjustments to provide the perfect position.
You may leave the T handle in place and lock and unlock one screw only near the end of the tuning session, leave the other silver Allen locking screw unlocked
The final position will not be dramatically affected when you complete the adjustments and lock the second screw
This is the best way to get to the final listening position. At the end lock both and listen, check the Azimuth at this point also
If you must adjust the 3 vertical height ½-20 location holes it is much easier to remove one of the plugs to allow air to enter. This is an airtight fit and this provides control of movement but also makes it tricky to overcome the vacuum when tuning the rough setting positions
The Digital Height control system withh 200x USB camera system is being developed now, stay tuned.
