Commentary
This is an authentic stereo set that can also be used as furniture.
Receiver section
The amplifier section uses a composite tube 6BM8 push-pull configuration and wide-band output transformer.
The head amplifier uses a combination of a new silicon transistor and a vacuum tube 12AX7 to achieve sound quality with less hum and noise.
A switching matrix circuit is used for the multi-circuit of the FM tuner section.
The output terminal of the center channel amplifier is mounted.
You can enjoy 3D stereo playback by connecting a mono amplifier and a bass speaker to this jack.
It is equipped with a noise filter that removes scratch noise from records, a loudness control circuit, an FM-AFC that stabilizes FM broadcasts, an SCA filter that shuts out interference from SCA broadcasts, and a tape monitor circuit.
It is also equipped with a headphone jack, ferrite antenna for AM and FM stereo indicator.
Player part
It is equipped with a player with an auto mechanism that adopts a newly designed mechanism.
Synchronous phono motor and 30 cm turntable are used for the mechanism part.
Equipped with auto return and auto cut mechanism.
A newly designed static balanced pipe arm with built-in bearing is used for the tone arm.
In addition, a 4-pole, 4-coil MM type cartridge is mounted in the cartridge part.
Speaker part
The speaker section is equipped with a 2-way speaker system.
It has a 25 cm cone woofer in the low range and a 7.5 cm cone tweeter in the high range.
Other
The cabinet has a walnut finish and is designed to allow for separate left and right speakers and center box.
The center box is designed with a vertical amplifier section, and has a structure with a shutter door.
