谢谢楼上的朋友!不纠结接隔离牛了,下面是美国功放设计者对我问题的回复。直接接古河滤波器算了。
It can be 115 or 230V and this is selected by a wire or wires that are soldered to the board.
Won't effect sound at all. The way the incoming AC voltage is handled changes, but the output from the power transformer to the circuit is identical regardless of AC line voltage (assuming voltage selection is wired properly).
Matt.
