The position of the stator is raised or lowered by adding or removing washers below the leather washer. In the ty

The damper spring must fit without binding or chattering, in the slot in the stator. The stator must be free to deflect in either direction between the limits of the da

The damper spring must exert equal force in restoring the stator to its mid -position when the stator is deflected manually in either direction. Tone Compensat

11、ion Because of the widely varying frequency characteristics of various types of audio amplifiers with which the Player may be used, it may be desirable in some cases to make refinements in the pickup circuit of the Player to compensate for the characteristics of the amplifier. The following circuits

12、 show means of making such refinements. In Figure 3, R1 controls the low -frequency response; larger values of R1 give increased lows: For maximum low -frequency re- sponse, remove R1. R2 controls pickup output, srnaller values of R2 giving increased output. Cl controls high -frequency response; to

13、increase highs, increase Cl. CRYSTAL PICKUP Cl -62MMf. I0,000 VOL: CONTROL Where a decrease in high -frequency response may be desired (for example, as an aid in reducing needle scratch on worn records), the circuit in Figure 4 is applicable. In this circuit, C2 acts as loading on the pickup and is

14、also a controlling factor on the high - frequency response. Smaller values of C2 give more pickup output and also more highs. R3 gives a sharper high -frequency reduction; increasing R3 decreases highs. The suggested values shown in Figures 3 and 4 should serve as a basis from which slight alteratio
