A masterpiece of old audio
I started working part-time in earnest, 1962, from the second year of middle school.
Summer vacation, winter vacation, almost, I have gone,
there is memory.
With the money I earned, I bought some audio products.
It was exactly the origin and mania (otaku) group.
First I bought Sansui's amplifier and trio (now Kenwood)
Tuner, cheap record player and speaker.
I feel that it was second hand goods.
(It was expensive and could not be bought new)
Besides the tuner and the amp, it was cheap.
At that time, "Audio Big Three" (San Tril Pi) is famous.
Initials of Sansui, Trio, Pioneer
Speakers are Onkyo, Sansui, Yamaha, DENON
Mitsubishi: DIATONE was famous.

Tuner, Trio (now KENWOOD), Pioneer is famous.
The Integrated Amplifier (Volume Amplifier),
Sansui, Pioneer, DENON was famous.
The tape deck was famous for Sony, Teac, AKAI.
The open reel tape deck I was using is the picture below.
38 cm (Sanpachi) tape deck for 4 channel stereo
1973, List price: 214000 yen.
The player was famous for DENON, Technics (Panasonic).
The picture below is JapanColumbia's 4 channel Integrated Amplifier.
Next, I was stuck with speakers.
I liked the crystal clear sound of the Victor speaker.
I like the tone, then the sound spreads well, multiway (3 WAY)
It became captive of the speaker. Woofer (bass),
Squawker (middle sound), tweeter (treble), with an amplifier,
independently,
You can change the volume. Eventually,
I reached Sansui's SP 2005. In the picture below,
I used it. It is SP 2005, 3 way 5 speaker system.
It was perfect for playing the orchestra's presence. These days,
Sansui certainly used JBL's speaker unit.
Therefore, I watched JBL products at Akihabara.
That's a wonderful word.
I thought that I wanted JBL, but that dream was too expensive,
I could not buy it again. It is frustrating.
I wanted the most, JBL 4345 and JBL - D 4400 - Paragon.

In addition, the multi-way has evolved to a more advanced 4-channel stereo
It will addict. There are multiway speakers around, left and right,
It controls the front and rear left and right speakers, furthermore low, medium, high tone
It was a revolutionary thing to control volume.
Discrete method 4 channel stereo: CD 4
It can only be played on a CD-4 dedicated disc (record disc).
There was a feeling of surround because the channel separation was reasonable. CD 4 is a method developed by JVC in 1970.
More, moreover, I saw an old dream.
From now on, the dream will continue from audio to microcontroller (name as initially released).
Old memories
I am planning to write personal computers as well.
Please expect and please wait.
