KUZMA STABI REF PS 2 TURNTABLE (without arm ) S/N……..
KUZMA LTD INSTRUCTION MANUAL FOR STABI Ref 2 turntable The Stabi Reference 2 turntable is a very precisely engineered piece of equipment. However the construction is robust and requires minimal maintenance for optimal performance. It differes from Stabi Ref only in the use of different power supply called PS REF 2.
General description Stabi Reference turntable is a suspended subchassis turntable. The main chassis, subchassis and platter are of an acrylic and aluminium sandwich construction which dampens all resonance of the turntable. The subchassis is isolated from the environment by four springs which are damped with silicon oil in sealed reservoirs. The suspension is easily adjusted via four knobs on the turntable top. The whole turntable stands on three large spikes. The bearing assembly is of an inverted type.
Unpackaging Contents: Stabi Ref is packed in a single main box. Inner box: platter, subplatter, PVC bottle with bearing oil, belt, armboard, motor controller, power cord and motor cable, Allen key 4 mm with 4 pcs screws for armboard, instruction manual, clamp with 2 washers. At the bottom of main box: Subchassis with bearing shaft and base chassis with motors. Removing parts: Prepare the surface where you will set up the turntable. Open the box at the top (see vertical arrows).
Base chassis Top subchassis: There are suspension adjustment knobs on four corners of the subchassis and in the middle is the shaft with a fixed ruby ball. Check the Note on page 4 regarding settling time for damping oil in the base chassis. Carefully position the subchassis above the base chassis and gently lower it onto the base chassis, ensuring that the motor pulleys fit into the holes in the subchassis. The gap between both chassis should be between 10 to 15 mm.
Platter: Position the platter on the subplatter, holding the platter with both hands at the sides. Due to the small gap between the lower edge of the platter and the top of the subchassis, do not hold the platter underneath. Hold it firmly, so it will not slip. Setting up the turntable Suspension adjustment: Adding or subtracting mass from the subchassis will affect its height above the base chassis. Height adjustment is by rotation of the black knobs on the top.
PS REF 2: Front panel General description: The AC motor controller unit generates a dual sine wave output to control rotation and speed of two AC synchronous motors. The signal is generated by a sophisticated computer based program. This allows for smooth generation of the sine wave with very fine choice of speed. Each speed can be selected, finely adjusted independently and then stored in the memory. The PS is factory preset. Connect the motor cable to the motor output.
Mounting armboard and tonearm: Be sure that you have an armboard with the correct pre-cut. Mount armbase on the armboard and then mount armboard on the turntable with four Allen keys. Fix firmly. The armboard can be fixed in both directions, so be sure you mount it correctly orientated. If necessary a second cut can be made on the armboard, but this is made of aluminium. Mount the arm as instructed in the tonearm instruction manual.
It is advisable to put a washer under the LP (thin for thick records and thick for thin records) before screwing the clamp down. Observe the outer edge of the LP. To start with this edge will be above the mat but will slowly lower too touch the mat. Hold the LP so that it does not rotate. If the clamp is screwed to much, the outer edge will begin to rise. Pressure should then be released by slightly unscrewing the clamp until the outer edge is touching the mat again.
Problems Platter not rotating: Motor controller unit- check if the red LED is on -green displays shows 33 or 45, if not re-plug MCU - check connection cables from MCU to motor Consult dealer or qualified electrician. Very slow start: Only one motor receives output from PS: MCU. Remove the platter and belt and check that the motor pulleys are rotating. If only one motor pulley rotates, disconnect the mains and connecting cables and check if there is a failure of the MCU.
Silver spike Transportation For short distances dismantle the platter, remove belt and disconnect all cables. Block the tonearm's tube and then the turntable with the subplatter can be transported as it is, providing that it will not be tilted more then 15 degrees, which could cause oil leakage. If the subchassis might possibly be tilted more than this angle you should remove the bearing oil and it is advisable to protect the ruby ball. Removal of the subchassis automatically seals the oil wells.
