  • Page 5: Unpacking And Basic Setup

    1. Unpacking Open the box carefully and remove top covers. The tube with vertical bearing points is packed separately (tube assembly) on the top of the box. Please do handle with care and when put aside, ensure that nothing is touching the bearing points. Bear in mind how you will handle tube with output cable.
  • Page 6 With 1.5 mm Allen key, release the height ring ( Fig. 3.) which is on the fixing pillar below the VTA arm tower. Now it will drop down and touch the armbase. Fix the ring again and release the VTA arm tower.

    3. Setting up the tonearm Connecting tonearm: Check the horizontal movement of the tube to ensure that the headshell will reach the inner grooves (approximately to the edge of record label), but will not travel to the centre of the record. Also check the arm wire loop and connect the tonearm cable into the phono sockets of the preamp.
  • Page 8 Balancing of the tonearm: Fix cartridge pins. Add extra counterweights to the lower threaded carrier as per chart below, until the tonearm is roughly balanced. Fig. 9. Knowing the approximate mass of the cartridge( add aprox 1 gr for screws and 1 gr for fingerlift), enables choice of the correct configuration of different counterweights.

  • Page 9: Adjustment Of Tracking Force

    zero is very difficult. Adjust it to be roughly balanced and increase tracking force with upper smaller counterweight. If this is too loose, hold the front part of the counterweight and rotate the rear part until there is a tighter fit, or lock it into position on the threaded carrier. Opposite rotation will make the smaller counterweight looser.

    Fig. 10. VTA tower side-rough scale 7. Adjustment of azimuth To make azimuth adjustments, release the two screws locking the mechanism at the centre top of the main tonearm tube, with Allen key 2mm. Under the main tube is a tiny rod with a hexagonal screw. Insert the Allen key 2 mm into the screw (it may feel loose), rotate it slightly and it will alter the azimuth.

  • Page 11: Adjustment Of Bias

    Fig. 11A Bias distance “X” For maximum tracking, it is advisable to set the bias by use of an appropriate test record, ie. those with tracking bands. Please do not use test records with blank space where the tip of the needle sits on the surface rather than in the groove.

    Adding damping oil: First insert silicone damping oil into the troughs. Let the liquid settle, before adding more. Stop filling, when you reach the silver lines about 3mm below the edge of the troughs. Removing trough: Removing trough using Allen keys 1.5 mm (vertical- Fig .13) and 2.5 mm (horizontal- Fig.14). Release fixing screw and pull away trough.

    2B: Cartridge is not reaching inner grooves: check that position of the tonearm is correct with protractor for distance 344 mm and spindle to armbase distance is 291 mm. 3. Headshell cannot be removed- check that the screw is released enough with Allen key. Kuzma Ltd Hotemaze 17A SI-4205 PREDDVOR...
