Symphonic 65

Because the Symphonic 65 is pictured with the Clavinet D6 in the April 1973 Hohner Catalogue I've been translating, that's the first instrument I turned my attention to after translating the entries for the Universal-Pedal and what I consider the "core" instruments:  Pianet, Clavinet, and Electra-Piano.  (The Cembalet doesn't appear in the catalogue, so I suspect it was out of production by this point.)

Here's the entry itself:

My translation is below.  As with the other entries, I'm not sure of the accuracy of some of the technical terms (especially "Einschwingvibrato," which I translated as "transient vibrato").  The phrase "stufenlos regelbar" occurs a number of times.  "Stufenlos" is literally "step-less," but I translated it as "smoothly."
