There was a conversion from dual-capstan to single-capstan at the source for the CT-2307A because many devices had problems with band loop formation .

For this purpose, the left GA roll has been removed by Quelle Customer Service.

The left rubber pressure roller is no longer available from the factory on the model CT 2337, i.e. the change has already been made from the factory and not subsequently by the Quelle customer service.

The mounting point or the mounting/retaining mandrel of the left GA pressure lever of the CT-2337 has been changed from a snap ring to a mounting by nut ex works, as well as the band pressure guide and fork and return spring !

In addition, the potentiometer board of headphone amplifier on the CT2337 has been changed.

There are often rewinding and rewinding problems - The cause is often a defective idler... (A prov.Repair is possible through a hardware store O-ring)

The device was offered for 599/699 DM.

Known problems:

- Rewinding and rewinding no longer works due to worn idlers.

- Synchronization problems with height fluctuations (usually at the end of the band).

The drive has a similar design to that of the Telefunken RC-200 deck. However, the RC-200 is a single capstan drive without backband control. Many parts from this deck are identical in construction and can be exchanged crosswise.
