Notes

• The system RFT-Kompakt was developed in the context of a competition initiative in honor of the 25th anniversary of the GDR and represents the first compact system of the GDR.

The individual components of the SC 1700 are technically identical with Ziphona Opal 216 (record player), Ziphona Tuner 920 as well as the Ziphona HSV 920 (amplifier).

• The system RFT-Kompakt was presented to the public for the first time at the Leipzig Autumn Fair 1974.
