permanent magnet on the Capstan dissolves, particularly for Transport. Leads to fast grinding noises! All DD Drive drives AR350
Cog wheel of the winding disc drive can break/ tear! Pos. No. 130/ ET. Nr. RDG0034 -> No longer available!
Trembling 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!

Direct drive: The drive drive is without belt. A permanent magnet is attached to the capstan oscillating mass, which is driven by an electromagnetic field. Nevertheless, there is a belt - for the motorized cassette compartment. It is commercially available.
