Lenco L 55/S (1976):

The Lenco L55/S is not only the only turntable built in Italy, but also the only turntable with pulley transmission (Idler wheel) on the market that can be called ''high-fidelity''. For the first time it was introduced in 1976, featuring an S-shaped arm and the new plinth design. The exceptionality of this old design is demonstrated by the fact that, although the basic structure of the machine has remained the same, the performance of the Italian models is of an excellent level.
The pulley transmission system adopted by Lenco is very particular: by moving the pulley parallel to the motor axis, it is possible to continuously adjust the rotation speed of the plinth between 30 and 87 rpm. Three or two reference guides allow the user to position without hesitation the speed adjustment command at 33, 45 and 78 rpm. The position of the guides can be easily adjusted and a small stroboscopic disc is supplied as an accessory. The platter is exceptionally heavy and characterized by a very high ''moment of inertia''; this feature means that in case of an instantaneous power failure there is no significant speed fluctuation with the consequent ''meow'' type. Under normal operating conditions the Wow and Flutter is very low; 0.08% (unweighted value), 0.005% (weighed value).
It is a product characterized by an incredible robustness and reliability, with a lid of good workmanship.
