Remarks[edit]
- The drive is without belt. There is a permanent magnet attached to the capstan flywheel, which is driven by an electromagnetic field.
- RS-BX727 -> this unit has an IR receiver. The RS-BX727 was released in October 1992 and replaced the RS-BX707.
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
- Gear wheel of the winding disk drive can break/ crack! Item no. 130/ ET. No. RDG0034 -> no longer available
- Trembling in the sound: Lubricant of the winding plate axles flocculates! Re-lubricate with graphite grease
- Clay leaks: Spring of pressure roller gives way. Item no. 120-1/ ET. No. RUW140ZC -> no longer available
For your consideration
- Due to age, the plastic elements in the drive become increasingly brittle and break, the pinions of the rewind motor burst open and slip off => irreparable.
