Pianet N

Here's the entry for the Pianet N in a Hohner catalogue from April 1973.

I translated the text, although I'm not sure of the accuracy of some of the more technical terms.

HOHNER - Pianet N 

A polyphonic keyboard instrument with a sound similar to a piano, excellent accompaniment for singing associations and music groups. 

The tone reproduction occurs through connection to a good radio set or amplifying equipment.  For especially demanding performance with reference to note volume, above all in large rooms, we recommend as amplifying devices the effective HOHNER-Orgaphon-Amplifier or the Hanging-Amplifier.  Connecting jack for headphones "silent playing"; for this we recommend headphones with low ohmage.

61 piano keys of normal width, range: F1-f³ = five octaves; tone generators out of stainless steel with capacitive pickups, vibrato, connection jacks for amplifier, small and large signal sensitivity; wooden macoré housing, black legs, easily screw off, easily transportable, mains connection switchable 110-130, or 210-250 V alternating current, power consumption about 10 W, built-in mains outlet for the connection of the Hanging-Amplifier or an-other amplifier.

And for the sake of completeness, here's the separate entry for the amplifier:

Combined with the Hanging-Amplifier, the HOHNER Pianet N becomes an independent musical instrument.

The Hanging-Amplifier has an output of about 12 Watts and is hung on rubber pads that are screwed onto the instrument.  High- and low-regulation.  2 excellent broadband loudspeaker.  Phono-connection, mains connection switchable 110 or 220 Volt alternating current, power consumption about 40 Watts.
