Sharp GF-5757

The GF-5757 was a midsize boombox from Sharp. Most likely from somewhere between 1983-1986. The service manual says it has 12 CM woofers and "horn tweeters" (which I assume are piezos). Its output power is 2x3W RMS. It was available in two colors - silver or gold. Also, some had black grills while others had silver grills. Model codes included GF-5757H, GF-5757HB, GF-5757HG, and GF-5757E.

There were also two other Sharp models that used the same body shell: GF-6565 and GF-454.
