Special features

The "PXS" capacitors in the signal path have now reached the end of their life cycle, which is noticeable by bass loss, channel inequality and undifferentiated sound. Since these capacitors are also installed in the power supply, failures due to short circuits or hum disturbances due to loss of the screen action may also occur in the medium term. However, the originally very good sound quality can be restored by an expert revision.

Improved sound quality should be achieved through high-quality PXS-Capacitors
microphone input

permanent magnet on the Capstan can be solved, especially for 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 slip => irreparable
