哦，听威马说是NAD比较老的唱臂。真不靓声啊？rega2手上海要卖2500！！太贵了：（可参看http://207.228.230.231/info/NAD_5120.pdf以及http://digilander.libero.it/bellocaddo/turntablesgalleryHP.htm
5020 5120 This was a very cheap turntable, made in Czechoslovakia, and yet it had a reputation for good sound quality. It could be had with two arm versions: one quite conventional, the other without a real arm tube, but with a long narrow piece of printed circuit board connecting the headshell to the bearings (seen here). Both arms could employ viscous damping (SME and Graham have this too :-), and the platter actually existed of a thin metal plate supporting a very thick and heavy rubber mat.
谢谢ERIC鼓励，我要向各位前辈多多讨教，大家一定要帮我搞好哦，不然就丢大咯：）哈哈
