SANSUI APS-430
¥ 159,800 (1 unit, around 1970?)
Commentary
This is a stereo set with high sound quality by introducing a combination lattice design and Sansui's amplifier technology.
Receiver section
The output section uses a three pole output tube and a high-capacity, wide-band output transformer.
The head amplifier uses a silicon transistor and vacuum tube DC ignition system to reduce hum and expand the dynamic range.
A low-impedance cathode-follower recording terminal is used to prevent wiring from lowering the high-frequency range.
In addition, tone control of the cathode follower drive provides sound quality from low to high range.
Player part
The player uses a 4-pole synchronous motor.
The cartridge uses MC type.
Speaker part
It is a 3-way configuration equipped with a 25 cm cone woofer, 12 cm cone squaker and horn type tweeter using a powerful magnetic circuit. The network section is equipped with a full-scale 12dB/oct network.
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.
