AKAI 3000D
¥ 46,500 (around the late 1960 s?)
Commentary
3-head stereo tape deck.
Since recording and playback are performed by separate heads, the playback sound can be monitored while recording.
A computer-style form into a card silicon transistor preamplifier is incorporated to reduce hissing.
S/N has been improved by adopting a shield head.
The 2-lever system has been designed to ensure reliable operation and robustness.
Equipped with automatic shut-off, temporary stop lever, tape cleaner, equalizer for each tape speed, DIN jack and headphone jack.
Equipped with 3-digit tape counter with reset button and 2 VU meters.
Equipped with a universal power supply voltage switching device, it can be freely changed between AC100V ~ 240 V.
