Monophonic portable single recorder for mains/battery operation
Although such devices were up-to-date twenty years ago, this single recorder is still currently being manufactured (as of 2012) . It is mainly sold on the Eastern European market, but is also available in Germany via shipping.
The recording and playback quality are rather below average, but the device is very robust. In particular, the lifting / pressing mechanism for the sound head and the pressing roller, unlike in comparable devices, is not exclusively mechanically coupled to the Play button, but is gently supported by the drive motor during the starting process. As a result, both the mechanism and the tape are treated gently, even with rough handling of the play and cue buttons.
The author is aware of several devices that - despite "hard use" in the children's room - still work perfectly even after almost 20 years.
