AKAI AA-5000/AA-5000S
¥ 42,000 (around 1967)
Commentary
A solid-state pre-main amplifier using transistors.
A silicon power transistor is used at the final stage of the power amplifier section.
In addition, an EPC circuit is mounted as a protection circuit to protect the power transistor in case of an accident such as output terminal short circuit.
OTL system is adopted.
A built-in equalizer for the tape head allows direct playback from the head.
Equipped with DIN jack and stereo headphone jack.
Equipped with stand-alone high / low filters and tone control.
* The difference between AA-5000 and AA-5000S is unknown.
