10、22-1 Record Damage: Records containing heavy bass response in the region from 50 to 80 cycles may be subject to damage from groove or wall breakdown asa result of mechanical -acoustic feedback into the pickup unit. Subsequent playing of records so damaged results in abnormal distortion during the lo

11、w frequency passages. This condition can berectifiedbyremovingordisplacing the mechanical and electricalresonances, and the undesired mechanical coupling that contribute eithersingly,or which may be accumulative. The following operations should be carried out to effect the necessary remedy : (a)Inst

(b) Check lateral movement, of tone arm and adjustits associated parts to prevent any tendency to bind. The tone arm, rear lateral bearing

13、, the twist of the pickup cable where itpassesthroughthisbearing,andthe adjustment of the friction finger should be especially noted. (c) The pickup unit should be examined and adjusted toassurethatitiscorrectly centered, that the attachment of centering spring to the armature is secure, and that th

14、e clamping of the spring to the magnet assembly is solid. (d) The motor mounting springs should have the proper flexibility.To be certain that theseare correct,use StockNo.4562 which includes the following: TO ADJUST RISE AND SWING OF TONE ARM -WITH MANUAL INDEX LEVER IN12 POSITION AND ROLLER ON MAI
