这个6sn7是好东西. Sylvania 40年代铁座6sn7w,声音一流,在美国产所有品牌和年代的6sn7类管中属于最高水平了,综合素质并不输Mullard ecc33和ECC82,由于相当稀少,市场价格比较混乱. 国内二手叫1千多到两千多一对的都有. 全新的在国外400-500USD都有
图上这两只应是二手的,一个8成新,一个9成新, 参数相差10%,勉强算配对吧. 个人觉得价格在1000-1500比较合适.
需要注意的是6sn7W不一定能代替6sn7GTA/GTB, 他们的最大屏压不同,这个要问问Spark的工程师了,如果屏压不高于200V就可以用6sn7W.
关于6sn7w看看老外的评价:
very smooth and balanced, clean presentation, fantastic detail, very tight-clear bass and
superb accuracy, nice 3D soundstage, all have black rectangle shaped plates with internal metal support rod)
(#1 top rated US made 6SN7 in VTV magazine)
"When I put the 6SN7W into my preamp the other night, my
mouth literally hung open -- the difference in sound
was night and day -- a film composer buddy of mine
stopped by -- we put on a couple of his soundtracks --
his comment was that he'd never heard his music
reproduced in such a natural manner --"
