Radioconstructor `` Start-7217 '' (Generator for erasing and magnetizing a tape recorder).
Radio and electrical constructors, sets.Magnetic recording and playbackThe radio designer "Start-7217" (Generator for erasing and magnetizing a tape recorder) has been producing the Kamenets-Podolsk plant "Electropribor" since 1988. The radio constructor `` Start-7217 '' is intended for children of senior school age and radio amateurs of any qualifications. The proposed radio constructor allows you to assemble a generator that generates erasure and bias current for a magnetic tape during recording. The generator can be used in the manufacture and modernization of tape recorders of various classes. At the same time, if the tape drive mechanism of the tape recorder allows, the parameters are not worse than the 1st class. The frequency of the erasing and magnetizing current is 100 kHz. Erasing current 100 mA. Harmonic distortion 0.5%. Supply voltage (bipolar source) 12 V. Current consumption 35 mA. Board dimensions 130x80x40 mm. Weight 120 g.
