Commentary
Stereo record player with MM type cartridge.
A 4-pole synchronous motor is used. The motor is equipped with an oil supply pipe, and oil can be supplied from the oil inlet on the player board.
The pickup part uses a static balance type. The cartridge uses a moving magnet cartridge that uses a diamond needle.
The needle pressure is adjusted by changing the cartridge by rotating the counter weight at the rear end of the arm to the left and right.
The output of the pickup is taken out by a shield cord with a standard pin plug.
The shield cord and cartridge lead wire are connected using a 5-pin plug on the player board and an outlet.
An elevation mechanism has been adopted in which the pickup is moved up and down by the lever operation without accidentally damaging the record board or needle tip when operating the pickup.
Equipped with speed switching mechanism, 3 speeds can be switched.
In position 0, the power supply of the motor is turned off by the linked switch, and at the same time, the idler is separated from the turntable and motor pulley.
A 30 cm aluminum turntable is used for the turntable, and up / down deviation of the turntable is ± 0.05 mm or less.
The player board is made from 1.6 mm thick iron plate.
The wooden stand is fixed to the player board for protection during transportation and can be used as it is.
