TRIO ST-1100X
¥ 235,000 (around 1966)
Commentary
High-end stereo component for FM multi-broadcasting.
The ST 1100 x is composed mainly of Trio's top-of-the-line FM multi-stereo tri-amp.
Receiver section
The FM tuner section is equipped with a high-sensitivity FM multi-stereo tuner using New Vista, triple varicon and double limiter.
The AM tuner section also contains an AM tuner with high frequency amplification that is comparable to the sensitivity of a communication type receiver.
Player part
The player uses a direct needle pressure reading pipe arm and a hysteresis synchronous motor.
The MC type stereo cartridge V-45 is used for the cartridge.
Speaker part
3-way 4-speaker configuration is adopted.
A 30 cm cone type woofer is installed in the low range.
The mid-range is equipped with a 10-cm cone scoker, and the high-range is equipped with two horn tweeters.
