Aiwa Mini Series 30
The "Mini Series 30" was a set of stereo components sold by Aiwa, beginning in 1980. There were two different packages you could buy: The M-301 system (first photo), which has a separate power amp (SA-P30, 2x35 watts) and pre-amp (SA-C30), or the M-302 system (second photo), which has one integrated amp (SA-A30, 2x20 watts). Both systems used the ST-R30 tuner and the SD-L30 cassette tape deck.
Other optional accessories: AP-D35 or AP-D50 turntable, oak cabinet RK-G3, and bookshelf speakers SC-E1 or SC-G33.
