No sound, no recording:C619, C620, C621, C622 & C624 -> Renew 1000uF-10V
Permanent magnet on the capstan may come off, especially after transportation. Leads to fast grinding noises! All DD Drive drives AR350
tremble in the sound: lubricant of the winding plate axles flakes out! Re-lubricate with graphite grease
The sound is fading: the spring of the pressure roller is giving way. Pos. No. 120-1/ ET. No. RUW140ZC -> no longer available
Due to age, the plastic elements in the drive are increasingly brittle and break, the sprockets from the rewinding motor burst and slide off => irreparable
