DIATONE DP-82B
49,800yen(November, 1969 release)

Description
 
It is the player system which added improvement to DP-81B and was put on the market.

The hysteresis synchronous motor of 4 pole 16 coil capacitor starting is adopted as a motor.
Moreover, it was considered as the belt drive system by the polyurethane endless belt which carried out precision polish of both sides, and the stable play is realized.

The 31cm thing which gave precision processing is adopted as a turntable.

The absent-resonance static balance type pipe arm is adopted, and the plug-in head shell system of the Europe type needle pressure Direct-reading type is adopted.
The lateral balancer and the inside force canceller are carried. Moreover, the unnecessary "Direct-reading type needle pressure impression system" of a needle pressure gauge is adopted as adjustment of needle pressure.

The cartridge is equipped standardly with IM type cartridge of the high compliance type which adopted the maintenance mechanism of the establishment meter.
