Clinamen - Lenco turntable level 4 & Level 5 description

 

DESCRIPTION


As you have already read, Clinamenaudio firmly believes in the superiority of idler-wheel turntables. When it is implemented properly and with engineering know-how the heights of musicality and emotion that can be achieved with these devices are simply unreachable with a ‘belt’ transmission. The belt is an elasticated element and the coupling transmission always brings micro slips and irregularities. Even the modulations of the groove in the vinyl lead to small variations in speed. Our brain can perceive these phenomena no matter how small. The words that spring to mind after listening to a good bull-wheel turntable are: sense of rhythm, involvement and dynamics.

We, at Clinamenaudio, are committed to the idea of idler-wheel transmission and we have recognized the brilliance of the LENCO design. It is the only idler-wheel turntable where the pulley engages perpendicularly to the platter. Furthermore it has the possibility to continuously vary the speed, letting the pulley slide along the axis of the conic section motor. Nothing is simpler and more brilliant.

 

Thus we decided to offer two turntables which use the design of the LENCO’s transmission as a starting point. Physically the only things they have in common with the turntable is the motor and the  tonearm that supports the bull-wheel. The rest is Clinamen custom.

Many people have legitimately asked us: why not replace the motor, too? Because the rotor of the Lenco motor has a very high moment of inertia (a good 300 g•cmq) which is a value hardly achievable by a brushless motor; we consider this parameter very important indeed.

Let’s analyze in detail the problems that afflict the original Lenco turntables. We can list them as such:

 

Frame: the Lenco frame is unfortunately made from cheap printed 2mm metal plate. As well as being resonant, this is not sufficiently rigid, especially in the area of the spindle. Indeed there are differential flexures that compromise the reproduction quality.

Tonearm: the tonearm of the Lenco, despite having historical and collectors value, is unfortunately not suitable to guarantee a suitable tracking of your pick up. Barely damped, non-rigid, short and with too much play.

 

Plinth: the plinths supplied with the Lencos are simple frames of particleboard with veneer. Again, we are quite far from the necessary care that a no compromise bull-wheel device needs. In our turntables we use plinths made of a block of beech plywood.

 

Spindle: first of all we think that the original Lenco pivot is discreetly quality, but improvable. The housing of the thrust bearing sphere of the Lenco pivot is barely sufficient to support the weight of the heavy original platter of 3.3Kg. WE STRONGLY ADVISE AGAINST stacking platters. In the great majority of spindle we have inspected we have found that the plate under the steel thrust bearing sphere was deformed. Can you imagine what would happen with double the axial load! Furthermore the original spindle has often too much play with the brass bearing due to wear and tear. Another problem of the original spindle is the flexing of the hub. These concurrent issues cause imprecision in the reading and instability of the acoustic scene.

Platter: In a view of top quality the decent Lenco platter can be replaced by something heavier, more balanced, damped and most of all with greater momentum of the motion quantity. We can obtain this by increasing the diameter of the platter and concentrating the mass on the periphery. Furthermore by increasing the thickness of the platter it is possible to eliminate the ‘scraping’ noise caused by the pulley interacting with the original thin platter.

 

So we propose two turntables, differentiated on two levels : L4 and L5.  Here there is a Clinamenaudio plinth made of a block of beech plywood, Clinamen custom spindle and platter, top of the range tonearms supplied (Rega Audiomods six in the level 4 and Thomas Schick 12” in the level 5). The L5 has a bigger plinth designed to mount two tonearms. Also for L5 we have provided for the option ♯ (diesis), which supplies the same products but with better ‘accessories’.

It is important for us to supply turntables with our accessories and designated tonearms because we think that in an analogic device everything works in synergy to reach the desired goal; by supplying each part of the turntable we can guarantee the result.

 



Level 4 (L4) 

 

With our level 4 we have the Clinamen solid plinth with 5 x 18mm layers, total thickness of 90mm. Spindle and platter are our own Clinamen custom products. For the description of spindle and platter follow the link or read below in the description of Level 5.

 The plinth hosts one tonearm only, the new beautiful Rega Audiomods series 6, 10.5 inch long, interfaced to the plinth through our 20mm thick slate board. The phono cable is an 1877 Phono.

The main features of the L4 turntables are:


  • Clinamenaudio Plinth 90mm thick Beech plywood, matte lacquering in a color of choice or transparent matte.
  • Plinth dimension: 540 x 400x 90 mm
  • Tonearm Rega Audiomods Series 6
  • Slate tonearm board
  • System of stainless steel mirror polished Clinamenaudio BTF3 plates
  • 3mm thick cork mat
  • Set of 4 ERGAL anodized coupling feet
  • 12 mm oversize Clinamen custom spindle
  • Clinamen custom platter, diameter 320 mm made from ERGAL, 5, 4 Kg weight,  choice of color black or gold.
  • Pentapolar cable 1877 Phone
  • Price of the turntable 6,400 Euros
  • + 130 Euros for polished lacquering of the plinth
  • 5 mm Plexiglas dust cover 220 Euros

Level 5 (L5) 

 

 

This is the top range of our idler-wheel turntables designed around the Lenco transmission system. In the L5 the plinth beech plywood is made of 5 layers made from a block with a total thickness of 84 mm and a weight of 17 Kg. The diagram dimensions are quite imposing, 480x570mm because the plinth is able to support two tonearms, a 12” and a 9”.

The L5 is sold as standard with a 12” Thomas Schick tonearm mounted on a slate arm board. It is an excellent tonearm at unrivalled value for money. Its best features are simplicity, fluidity of joints and extremely low building tolerances. Its mid-high range perfectly matches the natural path of the Clinamen Sound, making it possible to use MC cartridges with medium compliance which we prefer.

The tonearm is equipped with our limited edition headshell made from cocobolo tone wood which we think is more musical compared to the original graphite headshell supplied by Schick.

 



 

We also supply a second slate board with REGA boring (222mm distance for pivot-spindle). Other 9” tonearms can be mounted and Clinamenaudio can supply the relevant board on request.

What makes this Clinamen L5 idler-wheel turntable unique, though, is the use of a new dedicated platter and spindle. They are top of the range quality. The new platter we produce is made from ERGAL obtained by milling in order to have the centesimal control over geometrical dimensions. Its diameter is 320mm.

The platter weighs 5,4 Kg, around 2 Kg more than the original. The advantages of this platter, as well as the obvious one of the greater mass, are: 


  • Much bigger diameter than standard – this means that the mass distributed on the periphery greatly increases the momentum of the quantity of motion (shuttlecock effect) supplying the platter with huge rotation constancy, much higher than what we’d hypothesize due to the mass increase.
  • Greater thickness of the platter – this implies a greater insensitivity to the vibrations perceived but most of all to those generated by the rotation of the underlying bull-wheel (practically zero scraping effect).

 

 

The spindle is completely custom made; it is our own design and implementation. For its description please refer to the dedicated article. In brief we can tell you here that its diameter is 12mm against the original 9mm. The length is also greater to offer better resistance to flection. The pivot made from CORRAX stainless steel undergoes a thermal treatment to increase the surface hardness up to its core (against Martensitic quenching that works on the superficial layer). In its final end the pivot carries a carbide bit (tungsten carbide englobed in a metallic matrix) with anti-friction TiN coating, which interfaces it with the sphere supporting the axial load. The thrust Pad is made from copper with an oil drain pan.
