Remarks

Occurring errors:

  • No sound, no recording:C619, C620, C621, C622 & C624 -> replace 1000uF-10V.
  • Permanent magnet on capstan can come loose, especially after transport. Leads to fast grinding noises! All DD Drive AR350
  • Trembling in the sound: Lubricant of the winding plate axles flocculates! Re-lubricate with graphite grease
  • Sound leaks: Pressure roller spring gives way. Item no. 120-1/ ET. No. RUW140ZC -> no longer available
  • Due to age, the plastic elements in the running gear become increasingly brittle and break, the pinions of the rewinding motor burst open and slip off => irreparable

For your attention Due to the age, the plastic elements in the drive become increasingly brittle and break, the pinions of the rewinding motor burst open and slip off => irreparable
