"Tapegrammophone", is a suitable name for this thing. It comes from a furniture that also
had a radio. Unfortnately this furniture had a too close contact with a bulldozer on a
scrap yard. The furniture could not be saved, only the Tefi unit was not too broken.
A casette can hold up to 4 hours of music, the tape is endless, it is transported by some rubber rolls, and
a grammophone pickup reads the tape that has a track like a grammophone disc.
A discomfort is the long lead-in, that is even equipped with a waiting signal (sound example).
The Tefi system never got widespread.
