Goka Azimuth&VTA Alignment Block

Why we have to use Azimuth & VTA Alignment Block?

The diamond tip must be set orthogonally to vinyl for accurate performance. The body of the
cartridge is built orthogonally when the upper lines of the angle are parallel to the surface of the
vinyl. From this angle setting, azimuth is the front line horizontality of the cartridge and vertical
tracking angle (VTA) is the side line horizontality of the cartridge. Our Nasotec Azimuth & VTA
Alignment block is the best tool for easy adjustment.

How to use 
Check the balance of turntable first.
1. Put the Azimuth & VTA Alignment Block at platter parallel in front of your turntable.
Check if the level is placed at the center. If it is not, raise footers at the opposite
side of the position where the bubble is higher at level until it is balanced.
2. Put the Azimuth & VTA Alignment Block at platter parallel to the side of your turntable.
Check if the the level is placed at the center. If it is not, raise footers at the opposite
side of the position where the bubble is higher at level until it is balanced.
3. Check steps one and two until the turntable is fully balanced.

Preparations for azimuth & VTA alignments
1. Put a flat vinyl on your platter. If your record is wrapped, use our record Clamp or
Record Weight to make it really flat. Otherwise, you can use a thin paper for easy balance.

Setting of correct azimuth
1. Put the block at the center of the record in the direction of the spindle horizontally using the
level.
2. Swing and place the headshell in front of the block.
3. Lower your headshell on the record by using the lifter.
4. Check the front line of the cartridge if it is parallel to the line of the block.
5. If both lines are parallel, the azimuth is ok. However, if it is not parallel, loosen the screw of the
arm connector slightly and adjust by turning headshell to the right or left.
6. This must be handled with care.

Setting of correct VTA(Vertical Tracking Angle)
1.Swing and place the handshell inside of the tracks.
2.Put the block in the exreior side of the recrd in the direction of the tangent of the groove horizontally using the level.
3.Swing and place the headshell behind the block.
4.Lower the cartridge by using the lifter.
5.Check the side line of the cartridge(or headshell)if it is parallel to the line of the block.
6.If both lines are parallel,VTA is ok.However,if it is not,loosen the arm height adjustment device and adjust the arm upward and downward.
