Stereo tape recorder constructor.
Radio and electrical constructors, sets.Magnetic recording and playbackSince 1982, the designer stereo tape recorder has been produced by the Astrakhan machine-building plant "Progress". The knstruktor consists of three complete blocks, made on a printed circuit board with dimensions of 125x90 mm. This is an amplifier for playback, recording, a unit for signal level indicators, an RF generator of erasure and bias currents, a rectifier and a power supply stabilizer. The constructor includes wires, variable and fixed resistors. The kit is intended for modernization of reel-to-reel tape recorders. Using the kit, you can turn a mono tape recorder into a stereo or improve the parameters of a stereo tape recorder, since the characteristics of the kit correspond to the 1st class of complexity. The playback amplifier has a frequency range of 30 ... 20,000 Hz at a speed of 19.05 cm / s and 30 ... 16,000 Hz at a speed of 9.53 cm / s. SOI 0.2%. The signal-to-noise ratio at the line output is -52 dB.
