They are direct-current power supply unit and the tube preamplifier which
dedicated the control amplifier part to another case.
The large capacity power supply
transformer and the power supply unit which dedicated the filament constant
voltage circuit, the rectifier circuit, and the filter circuit are used as
separation and another case from the main part of amplifier. This is stopping
the bad influence to the circuit unit of a main part of AC hum noise by the high
voltage, filament voltage, etc.
A total of every four 6DJ8 [ one ] is
used for a RIAA amplifier part and a line amplifier part for every channel.
Moreover, the constant voltage circuit consists of 6JC6A 5651 for reference
voltages, and for error amplifier, and 6CG5 for series regulators.

Since the optimal load of a use cartridge is obtained, the
load change of the original micro jack system is enabled. This installs a micro
jack in a RIAA circuit, only inserts the lead of fixed resistance, and while the
spring with a built-in micro jack is realized with the system held lightly and
exchanges leads simply, it can choose the optimal load to a use cartridge.
As for the vacuum pipe of the audio stage, all adjustments including
bias adjustment are carried out before shipment. For this reason, the 6DJ8 [
same ] adjusts bias separately even if, respectively, and the color exception is
There was also a black model besides a silver model.
