The tape is placed inside a cassette and
has a playing time of one hour.
Later on, larger cassettes were released, with a playing

At the end of the 1950s, the company
introduced the first stereo cassettes
Tefi also makes radios after the war,
such as the small Tefi Zwerg and combinations of radio,
record player and Tefifon player. Television sets are
also part of the delivery program.
The Tefifon system seems to be successful, but the
increasing competition from the ever-evolving market of
gramophone records and tape recording devices puts an
end to the Tefifon system in the early 1960s and Tefi as
a manufacturer. In 1965 Neckermann takes over the
company and the products are sold in a closing sale. |
