  • Super 8 sound amplifier voltage.

    New here. Have a question. I have two Super8 sound, one Sankyo Sound 501, and one Chinon SP330, I'm trying to get going again, more about that later, but first why does the amp run on 29v and 30v when the chip inside is only for 12v. Ta7205P in the Sankyo, and TA7228P in the Chinon. Data sheet says it's made for car stereo. Does anyone know why. Thanks. Many more questions to come.
