'''Technical change'''<br />
+
== Bilder ==
Because it happened with some devices that the tape was damaged, a change in the winding motor control was recommended!<br />
 
Change:<br />
 
Ten diode D504 MTZJ5R6CTA is changed to MTZJ5R1BTA!<br />
 
<br />
 
  
'''Errors encountered:'''<br />
 
* No sound, no recording: C619, C620, C621, C622 &amp; C624 -&gt; renew 1000uF-10V.<br />
 
* Permanent magnet on capstan comes loose, especially after transport. Leads to fast grinding noises! All DD Drive AR350<br />
 
* Gear wheel of the winding disk drive can break/ crack! Item no. 130/ ET. No. RDG0034 -&gt; No longer available!<br />
 
* Trembling in the sound:<br /> Lubricant of the winding plate axles flocculates! Re-lubricate with graphite grease<br />
 
* Tone leaks:Spring of pressure roller gives way. Item no. 120-1/ ET. No. RUW140ZC -&gt; no longer available!
 
  
== Remarks ==
 
* Direct Drive: The drive is without belt. A permanent magnet is attached to the capstan flywheel, which is driven by an electromagnetic field. Nevertheless there is a belt - for the motorized cassette compartment. It is available in stores.
