Measurements of Taobao DIY PowerAmp Based on RuiKaiYing S30 Board

这台功放又是另一个好事的送测者提供的,根据外包装层层叠叠的快递单子来看似乎经过了不止一两手。由于本身机壳上面没有任何品牌标识我只能将其归类为TaobaoDIY功放。征得同意拆机后发现,这是一个安森美对管功放,功放板是瑞凯盈的S30

怎么说呢,这个壳子还是值两三百块钱的。只要不打开机壳,光看外部的话其实还可以。我一直好奇这玩意多少钱,送测者说一千多……那我就不怎么理解了。不管它,直接测量:

结论,基于这个电路的安森美对管功放的一致性还是挺强的,和之前测过的差别不大
