  • JVC QL-F6, 5. Replacement Procedures 5-( 1) Stylus Stylus replacement (See Fig. 2) Replacement of the stylus can be easily made by simply inserting the stylus plug (A) into the jack (B) of the cartridge. Service life of the stylus employed for this unit (DT- Zl EB) is generally as follow; varying, depend- ing on the record condition (dirty record groove etc. Stereo LP record (30 cm) . . . Approx. 300 - 500 hours Stylus are disposable items. Therefore, it is recommended to buy a supply of styli when you buy the unit. When purchasing them , specify the DT-Zl EB (JVC standard). 5-(2) Headshell Removal and mounting of the headshell (See Fig. 3) Turn the connector nut in the direction of " A
