Lo-D HA-200
35,000yen(around the 1974 time)

The Integrated Amplifier which uses the LTP transistor which pursued the Low-noise-izing, supplied the Hitachi semiconductor technology, and was developed.

The pure complimentary output circuit is adopted.

When bads arise, the circuit breaker which protects a circuitry and a loudspeaker is carried.

Mic amplifier is built in and mixing with other audio sources is possible.
