The

ROTEL RX-150A
29,800yen(around the 1973 time)

Description
 
The stereo receiver which asked for the performance on 1 class with low cost.

High-sensitivity FET is adopted as FM front end.

The interconnection change of two speaker systems is possible.

The tapes value monitor is carried.

4ch speaker matrix is built in.
