SANSUI SAX-200
¥ 44,700 (released in 1964)
Commentary
AM/FM multi-stereo amplifier with built-in FM multi-circuit.
The SAX-100 and SAX-200 were the first in the SAX series until around the early 70 s.
The output tube adopts a push-pull configuration of high-efficiency composite tube (3-pole, 5-pole tube) 6BM8.
The power stage has a voltage negative feedback (V-NFB) of more than 16 dB, reducing the internal impedance to approximately 1/8.
Equipped with FM multi-stereo circuit.
Switching matrix method is adopted for the circuit method.
Equipped with a head amplifier that uses four transistors.
We have chosen ultra-precision transistors especially for industrial measuring instruments, and are working to achieve an endless range of products.
Equipped with special terminals for condenser and tweeter.
It is equipped with circuits such as rumble filter, scratch filter, loudness control, friction tone control, FM multiplex, FM-AFC, and tape monitor.
In addition, an FM multiFM multi-indicator for tuning indication.
It uses a mechanism that the colorful scale rises when the power is turned on.
