How Record Players Work
Learn how record players work!
While CD players and cassette decks are more common, there are those who still use turntables. As a record plays, tiny variations in the walls of it grooves wiggle the needle (stylus). This motion is converted to an electrical signal by the cartridge and then the signal is amplified by the receiver and sent to the speakers.
Turntables can either be belt-driven, direct driven or may be driven by a idler wheel. Also, because the stylus wears with use, your turntable may experience a loss of performance and the needle must be replaced. From time to time, clean the needle with a soft brush and always use an antistatic brush on your records.
a.. Pull the stylus out gently.
b.. Clip the new stylus into its place.
To disassemble a turntable:
a.. Unplug the unit and lift off cover. Rotate the platter to access pulley through hole, then lift belt off.
b.. Pry the C-clip off the spindle. Be sure to keep one finger on the clip to prevent it from flying off (protect your eyes!).
c.. Lift platter from spindle to expose some of the serviceable parts. The belt can now be removed from the platter.To access remaining parts, secure the tone arm, install the dust cover and turn unit over. Remove bottom panel screws and lift panel off.
Replacing the belt
a.. Unplug the turntable. Remove the mat and reach a gloved fingertip into platter the access hole. Lift belt off of the motor pulley; then lift off the platter.
b.. Slip the belt off the underside of the platter. Clean the belt rim and motor pulley with a swab or replace the belt if damaged or worn.
Lubricating the turntable
a.. Apply white lithium grease to the bushing atop the platter gear. If the platter has a ball type bearing, remove, clean and grease it.
b.. Lubricate the tone arm bearing with lightweight synthetic lubricant by using just a drop or two. If you don't have a special oiler, apply a drop of lubricant with a toothpick.
