Marantz SR-1100 49,800yen(around the 1980 time)

FM / AM-stereo receiver which thought facility and smartness as important and with which the slim design was carried out.

The power amplifier block of the Low-TIM design by DC amplifier stream composition is adopted as an amplifier part.

In the tuner part, the dual gate MOS FET excellent in the normal-mode-rejection performance was carried in front end, and the outstanding receiving performance is gained.
Moreover, the tuning pointer and pilot cancellar of light emitting diode adoption which are easy to find the optimal aligning point are carried.

Functionalities, such as a loudness, a high light filter, a mic mixing circuitry, FM muting switch, and a LED indicator, are carried.
