Lo-D HCA-6500
29,000yen(around the 1979 time)

Control amplifier developed aiming at the low-distortion low noise.

The low-noise FET transistor was adopted as the first rank of an equalizer circuitry, IC for equalizers was adopted as the 2nd step, and the high property is realized.

It has the interrupt control logic-DC stream composition for tone-quality pursuit.

Tapes dubbing is also possible, enjoying a play of other sources.
