DIATONE DT-4100
29,800yen(around the 1971 time)

Description
 
It is a stereo cassette deck of a four two truck system.

The low distorted solid-state amplifier which uses 12 low noise transistors focusing on 2SC871 is carried.

The electronic governor motor is adopted as a motor so that it can use in both a 50Hz area and a 60Hz area.

And a motor stops automatically and a cassette jumps out at the same time it carries the stopper and a tape finishes.

The level meter which became independent to each right and left, and the slide volume of Recording-play combination are adopted.

The all push button system is adopted.

The tape counter is carried and a recording part is known.

The stop lever is carried.

Cassette rise equipment is carried and a cassette can be taken out only by pulling a lever.

The prevention equipment from incorrect recording is carried.

The headset jack, a 6.3phi microphone jack, a DIN jack, etc. are carried.
