2013年11月25日 · There should be little issue as a drop in replacement. Whether you will actually hear a difference is not known. Most people would not likely hear much difference unless the old chip was failing slowly and quite far along, especially in an electronic piano only because of all the other noise sources around you.

2013年12月26日 · 一块坏了一边声道的stk4171v： 不知道是不是原状货，拿去用x光透视拍照，还好不是塑封管拼装的。 解剖来看看，顺便量了一下电阻，功率管的be间电阻用数字表测量是188欧姆。 内部电路，好想知道r1的电阻是多大，估测下前级电流，可惜眼花缭乱不知道哪个是。
