Designed and manufactured by Ing. Franz Leben of Dachau, the Heimstudio (home studio) was built exclusively for the German Quelle mail-order department store. Quelle was founded on October 26th, 1927 and by 1936 had over a million mail-order customers – this had grown to 2 million by the outbreak of War in 1939 . In 1949, they opened their first department store in Fürth, Germany..
This machine utilised the Truvox 90 deck with piano key operation, positive lock reel carriers,
4 digit counter, hinged editing panel, three tape speeds and three motor drive with Papst capstan motor.
The controls were exceedingly simple, five piano key
buttons controlled stop, forward wind, rewind and play, the latter being
interlinked with a record safety button.
