KUZMA »4POINT« TONEARM
  
This differs from other arms by incorporating several unique features. The zero play bearing is configurated on 4 points. There is very precise VTA adjustment and, despite a longer effective length of 280 mm ( 11 inches), fits our  standard mounting distance of 212mm ( 9 inches).
The heart of the new construction is a unique 4 point bearing. The first set of two points  ( similar to a unipivot  bearing)  allows vertical  movement. The second set of two points allows horizontal movement. All four points have minimal friction and zero play in all playing directions thus ensuring the cartridge platform and the cartridge itself  move with  very low friction and minimal vibration across the record .
The whole construction is mounted on a rigid VTA tower which allows VTA adjustment while playing, without any loss of rigidity, yet with up to 0.01 mm of precision with zero play.
The main tube is constructed and machined from solid  aluminium as in  our tangentical Air line arm.
Two separate troughs damp  vertical and horizontal resonances and can be finely adjusted independently. The  troughs can be removed from the tonearm.
The main counterweight balances the tonearm  and has a  second small counterweight with which the  tracking force can be finely  adjusted.  
Azimuth can be adjusted in small repeatable increments with zero play, by means of an Allen key.
A feature of the tonearm is a unique detachable headshell. The electrical connection is via standard pins but the headshell can be simply removed by unscrewing with an Allen key. The headshell is fixed with  a hexagonal locking system giving the same rigidity as with a fixed headshell.
Internal wiring is of superior special  alloy silver wires.  One set of 4 wires runs from the cartridge pins to the termination box and further along  into a 1.4 m long tonearm cable with silver Eichmann bullet connectors in one unbroken length. The second set of 4 wires runs from the same cartridge pins to the termination box to female Cardas RCA connectors thus allowing  use of any RCA  plugged tonearm cable from termination box to phono preamp input. This gives  so called biwiring on this tonearm and a lot of flexibility with  choice of no compromise cables.
