Jensen JTA-230 Motor Replacement

はじめに

A record player can play music due to a variety of mechanisms. The contact of the stylus against a rotating record creates vibrations, these are converted into electrical signals which are then converted into sound. This all goes back to the motor. Without the motor, the record can't turn. Therefor replacement is necessary if the motor breaks. The Jensen 230 record player carries a 9/12 V DC motor. It is located inside the record player. Removal of the motor is fairly simple, however, some some further soldering work is necessary to replace the motor entirely.
