拜亚动力A2的拆解、维修、美容
我怎么总是发些奇奇怪怪的东西。。。前段时间从闲鱼收了个99新美亚A2，到手后发现顶盖上的logo造型透窗内侧有污渍，强迫症发作，拧下底部四颗螺丝后拆开机器。。。结果根本擦不掉。
擦不掉就擦不掉吧，用六角扳手一颗颗把螺丝拧回去时。。。悲剧发生。
A2整体是个三明治结构，底板+中框+顶盖。顶盖上粘了四个长螺套，与穿过脚钉、底板的螺丝结合，把中框夹紧。这耳放到我手里时，有颗螺套跟顶盖的粘接处已经比较脆了。。。捏着六角扳手一用力，就脱胶了。（见图一）
没办法，淘宝搜索“焊接胶”，买了ergo的1309（速干胶水此处不适用）。用刀片刮除螺套、顶盖上的残留胶水后，调胶、施胶、保压24小时，上螺丝，完美。
因为顶盖是钢化玻璃材质，上紧螺丝后其四角会有些弯曲变形。解决方法就是撕掉顶盖四边上粘的黑色泡棉，让它直接落在金属中框上。。。
最后是美容环节。。。淘宝搜“家具翻新贴纸”，找了款“加西铁杉2”纹理的，到手后仔细看看还挺像那么回事儿。裁了一块贴上去，用笔刀紧贴顶盖划一圈儿，再用安全剃须刀片精修下，拧螺丝装回去。。。最终效果很清新很小资。

污渍去不掉是挺烦人的，试过用刀片刮吗。你这感觉改的挺好的，楼主有点东西哈，支持一下 顺便贴个headfonia对A2的评价吧。。。
“The Violectric V200, which I just sold, is completely different sounding. The A2 has more clarity and detail with a bigger sound stage. The V200 is full bodied on the other hand, with more bass and warmth. Basically it's the same as the V281 when using the Single Ended out.”
“That being said, the A2 is awesome sounding and you really should audition it if you're looking for a new solid state headphone amplifier that also has a line-out (not pre-amp as I said before). The A2 hasn't been getting a lot of attention in our special headphone world and I don't think that's correct. It's a really great transparent amplifier with a top class sound and it should be talked about more.” boxerlc 发表于 2019-6-5 19:55

我也会觉得蛋疼哈哈，下回试试刀片刮，如果是表面污渍，而不是玻璃本身缺陷的话，应该能弄下来 好手艺！:lol
