TECHNICS SP10 MKII DIRECT DRIVE TURNTABLE WITH A WOOD PLINTH AND SH-10E SEPARATED POWER SUPPLY.
WORKING 100% PERFECT...
The SP10 MkII (with a SH-10E PS) was introduced around 1976 with a great step forward if compared to the MkI series and other Direct Drive turntables.
The functioning of the MKII was quite different, now the motor was turning at a given speed which was steered by a set frequency which was generated by a quartz crystal. Hence the turntable's performance is not affected by any altering in the frequency of the mains nor any voltage fluctuation.
A fluctuation in speed is instantly corrected by the motor itself without the use of a tachometer or a playback head which reads the magnetic imprints on the inside of the platter (a method Denon used in their DD turntables).
This meant a mere perfect performance as far as speed accuracy, wow and flutter are concerned.
In order to avoid fluctuations from temperature and those caused by mechanical parts no speed adjustment facility (variable pitch) was incorporated.
This was a drawback for people with perfect pitch and for those music lovers who wanted to play a variety of old shellac records which are not always cut at 78 RPM.
A new and unique feature of the SP 10 MkII was the incorporation of a mechanical and electronic brake not encountered on other DD turntables, not even the SP10MKI. It reminded of the direct start of the EMT turntables and the clutch of the Thorens TD-124 and it made the SP-10 Mk2 a true Studio Turntable. Many radio stations installed the Mk2 for playing 33.33 and 45 rpm discs for the broadcast of music programs.
By increasing the capabilities of the motor and designing refined and complex electronics to regulate the motor's rotation (for smoothing out the shocks when moving from one pole to the next) the SP10mk2 attained its practically incomparable specifications.
(Technics applied this principle -except for the breaking feature- lateron in the newer, less costly MKII versions of SL1300, SL1500 and SL1800. And these SL 1310, SL 1510, SL 1810, etc. got a new styling in the MkII versions. Although these turntables in the lower echelon were a step ahead of the earlier SL110, SL120 and SL-150, they could not match the sound quality of some high quality, heavy, belt drive turntables with a floating chassis or the Thorens TD-125 Mk2 for example.
Instead of the soft mat which was used on the earliest SP10 (SL1000) and SL110, now a hard mat adorned the heavy platter. The hardness is not without significance for the sound performance which is an essential feature of the SP10MkII.
The platter of the SP-10 MkII weighs 2.9 kg / 6.4 lb. to prevent a turntable platter from sounding like a bell, the inside has to be covered with a sound absorbing material. This can be a layer of a resin like substance as with the early Melco turntables or - as in the case of the Technics SP 10 mkii - with a relatively thick bituminous sheet. not in the middle part which is connected to the motor section.
The turntable has a starting torque of 6 kg/cm-2 (5.2 lb.inch-2). the moment of inertia is 380 kg/cm-2 (130 lbs.inch-2) a starting time of 0.25 sec. to reach the nominal speed.
