AEG Magnetophon K9 specifications

Category : Tape machines

The device K9 is very similar to the K8. The most striking difference is the angular buttons on this device. Original ly as a further construction, this device was also only for a belt speed of 76 cm / sec. designed. However, the device has a pole-changeable syncron motor with 4 and 8 poles and was able to drive two different belt speeds: 76.2 cm / s and 38.1 cm / s and was then named K9u.

The sound head mechanically corresponded to the K8.

The corresponding amplifiers V66u (recording amplifier / recording amplifier) and V67u (playback amplifier) were included in the scope of delivery. Alternatively, the device was also available in stereo version, i.e. as a two-channel device with 2 x 2 amplifiers each.

As a version for students and broadcasters under the designation T9a, the device was manufactured with an 8 or 16-pole motor, respectively, which made belt speeds of 38 cm/s and 19 cm/s possible.

In the course of the restructuring after the war, the responsibility for this device also changed: it completely changed from AEG to the Group subsidiary TELEFUNKEN, the production moved to newly purchased buildings in Wedel near Hamburg. The successor device received the designation M10, M for magnetophone.
