Rare Soviet/Russian Korvet GZM-128 mm cartridge.
Cartridge "KORVET" GZM-128 - stereo, the first group of GOST 18631-87 in, highly sensitive to the moving magnet, needle holders with beryllium and diamond mnogoradiusnoy (many faces) needle. The head is designed to convert mechanical recording of records into electrical signals. Features: Wide range of playback frequencies, high noise immunity and longer life. At the head of the needle used such as "parkas".(many faces) and crystallographic orientation of the working surface of the tip relative to solid edges of the diamond crystal significantly reduces wear and tear of records, and also the needle. The head is protected from interference from permalloy shield and counter-turning coils on each channel. Box head in order to reduce resonant vibrations of the moving system is installed damper. To protect the needle and moving the system from accidental damage visor made head turning. Dust from the needle is removed with a brush dipped in alcohol, moving it along the body and head to the tip in the lengthwise direction. The head comes prepared for the four-wire connection. For the five-wire connection should remove the jumper. Effective frequency range, the limited level of -5 dB, the lower the frequency of 10 Hz, the upper frequency of no less than 25 000 Hz.Sensitivity of the channel at 1000 Hz, mV * cm * sec. 1,2 ± 0,3. Channel separation, however, at frequencies of 1000 Hz 28 dB, 10000 Hz, 18 dB. Channel imbalance in sensitivity at frequencies of 1000 Hz, less than 1 dB. The horizontal dynamic flexibility of the moving system, mm * H-1, at least 20. Inductance mH 360 ± 60. Resistance, 1000 ± 200 ohms. Rated load impedance kOhm 47. Rated load capacitance, pF 150. Nominal static clamping force, 10 mN. Overall dimensions: length 41,0 ± 0,5 17,7 ± 0,2 width height 19,5 ± 0,5. The mass of 4,7 ± 0,3, the
