Electric turntable 'Phoenix-006-stereo'.
Electric record players and electrophones on semiconductorsDomesticThe "Phoenix-006-stereo" electric player from 1981 to 1987 was included in the production of the Lviv Telegraph Equipment Plant. The top-class stereo electric turntable "Phoenix-006-stereo" is designed for high-quality reproduction of mechanical recording from records of all formats. The technical description of the EP is not yet available, but there is a note about the model of the author of the photographs Alexander Maistrenko from Zaporozhye: The tonearm of the electric player is S-shaped. Shear force compensator - spring. There is a useful and rare function of adjusting the tonearm in height within 7 mm. In the vertical plane, the tonearm is suspended on 2 precision ball bearings. Horizontal - on one. They are spacing adjusted, pressed in and flared, so there is no backlash. In the tonearm, 4 wires of 7 wires of 0.07 mm of the "litz wire" type are used as signal wires. The same wire is used to ground the arm tube. Automatic EP mechanical. The auto-stop is made on a reed switch with a sensor in the form of a permanent magnet on the pivoting arm of the tonearm. An AC motor with a gear reduction gear is responsible for the movement of the tonearm. The connection of the engine with the control levers of the tonearm is through a drum with a connecting rod mechanism. On the drum there are protrusions that switch the limit switches, carrying out one or another kind of work of the electric drive. Direct drive motor, eight-pole with 4-lead Hall sensor. To operate the engine, a generator board on an op-amp and transistors is used. The octopole drives the rotor part with a permanent magnet. The rotor is supported by a high-strength steel insert on a fluoroplastic (caprolon?) Heel, which provides a coefficient of friction lower than that of a metal-metal pair. In the radial plane, the rotor is mounted on a sleeve bearing. The quality of the fit is so high that if you insert the rotor without a magnet into the bearing vertically and release it, it does not fall, but slowly descends. The motor with tonearm is mounted on a 40 mm chipboard plate with steel counterweight. The plate is attached to the body at 3 points on shock absorbers, which provides good vibration isolation from the body. The shock absorbers are adjustable in height, which makes it possible to install the plate with the tonearm and the motor in parallel in the horizontal plane, by means of simple adjustments. Disc weight 1.5 kg. The weight of the rotor part with the magnet and the disc is 3.8 kg, which has a good effect on the stability of the revolutions. The upper part of the EP is made of die-cast aluminum alloy and painted with matt paint with a thickness of about 1 mm. The weight of the device is 14.7 kg. In general, the production culture of the apparatus is very high. In my opinion, the EP is superior in level to Electronics B1-01. The device is quite rare. On all rack components I know, the numbers did not exceed 1000. On my motor number 666, chassis 786. The numbers 020 are present at the beginning of the numbers of all the devices I know and represent the factory code. My EP is 1986.
