如果老兄不用这西电油蜡喇叭线, 才能发挥这对12au7的真正实力.

过几天换换喇叭线试一下。谢谢DF兄指点

为了让DF兄可以更加准确的为三越产品的用家推荐合适的管子，避免上次因为管子在不同机器位置上的使用差异，我准备提供一台M34给DF兄试听和使用。

需要试听和使用的时间长短由DF兄决定，半年一年都可以，而且，来回的运费由我负责。

机器就是正常销售的M34，换古董瓷管电容，并配送原配的电容，和大家手上的机器是一样的。

不知DF兄意下如何？

老赵真是好人！

.......

老赵用M34来毒我了, 哈哈.

在Sanyue论坛交流古董管,本来是个爱好,这么一来老赵是叫我负点责任了哦.

看来为了Sanyue用户玩好M34,老赵真可谓费尽心思了.

谢谢老赵的信任,我尽力就是了.

老赵  赶快发机了 能包机更快  大伙等着代兄出成果呢！

呵呵，毒你只是顺带喽，主要是因为古董管子，不可以预料的状况很多，并不是主观故意，却还是容易判断失误，用了一个共同的平台，可以有效的避免失误。

再就是，有你的好管子，M34可以如虎添翼，大家交流，还可以研究一下，如何让稍稍平庸的管子在M34大放异彩？我这里，各种各样的好电容大把，知道大家喜欢的方向，调整不是问题，呵呵

再就是，古董管子，很复杂，找到好声音和质量的管子，并不是一件容易的事情，三越又不经销古董管子，肯定会有三越机器的客户需要DF兄指导甚至代购管子，有了同一或者近似的平台，有状况就可以事先知道，就少了往返折腾的时间了，大家可以玩的更加开心一些。

当然，如果请DF兄代购管子，就不能按照材料网的出货价格，毕竟，在材料网买东西需要花时间和精力的，知识、信息以及风险都要考虑到，应该适度的加一些价格，算是正常的回报，我觉得，在材料网正常价格的基础上，加价30%以内是合理的，运费不放在内，DF兄按照正常二手交易规定给于几天的质量保证，代买的商品，声音不合意，质量没有问题，肯定就是不方便退货的。

当然，大家也可以守株待兔的在材料网等待，有心仪的品种自己拿下，拿不定的时候，可以在这里咨询。

DF兄也请给大家一个指导意见，大家自己四处搜寻，有国外的朋友可以代购就更加方便了，呵呵

DF兄觉得可否？ 大家有什么其它的意见？

这个主意不错，支持！

我毕竟不是做管子生意的,在这里以交流和推荐为主, 大家可以到Taobao,ebay,材料网等地方自己寻找,找到后,我还可以帮大家鉴定一下真伪和成色. 

尽量别让我带购,假如有10个朋友找我代购的话,恐怕我就整天在找管子,不用上班了,呵呵

对于三越品牌机器的客户，为了避免意外，也让DF兄省一些精力，需要的话，管子都发到我这里， 我试听检查以后再发给客户。

好吧,那就先这么办吧.

欢迎DF兄回来。

DF：请问RCA JAN-CRC-6SN7GT VT231 与RCA5692哪个更好些？
我现在拿到一对ken rad vt231碳屏，是我听过的6sn7最好声的了，插上就不想拿下来，温暖、润泽、厚实。但一直想入上面的两个，据说更好，尤其是5692。麻烦介绍一下。谢谢！

5692是超低噪音,高抗震,长寿命设计的6SN7, 如果你追求低麦克风效应,大动态,快速度,背景宁静,长寿命,5692是很好的选择,以50年代RCA 红座白字5692最为出名.

40年代的VT231 从听感上讲并不输给 5692, 韵味甚至更好,只是并非高长寿命抗震设计罢了.后期的VT231=6SN7GT则差一些.


关于6SN7下面是老美的评价,供参考,我就不翻译了,呵呵
____________________________________________

Tung-Sol Round Plates, VT-231 or 6SN7 - Clean, fast, the best in everything, wide bandwidth, great resolution. If you can’t find the Music, it’s not the tube’s fault.

RCA VT-231, black plates, rich harmonic structure, beautiful timbre and voicing, wide soundstage

6SN7W or WGT Sylvania black plates – Tied for second and came in first if your system sounds a little laid back, especially some single ended amplifiers – Excellent low level detail resolution, very immediate sounding with a lot of Slam. There are three types of these tubes, two large bottle types, one has a metal ring and one smaller bottle with  smaller plate structure. The smaller one has better low level detail and the larger ones have more slam.

Raytheon VT-231, black flat plates - like the Tungsol a little sweeter, nice balance of detail and timbre

Ken-Rad VT-231, flat black plates - Great Bass, drive, sweet midrange, good bandwidth althought micrphonic tendencies on preamps.

Sylvania VT-231, black plates, wide bandwidth, well balanced, excellent sound stage and air.

Sylvania 1952 JAN-CHS-6SN7GT bottom getter: construction identical to the earlier VT231 but sonics are not, exceeds the VT231 in every respect, real bad boys excell in every area, big tight bass, warm detailed mids, extended smooth highs, very open

National Union VT-231 - good drive and great midrange, softer bass and a touch euphonic

Tung-Sol 6SN7WGT, Black Plate, brown base – Sounds similar to the Tung-Sol VT-231, not as clean

Tung-Sol 6SN7WGT, Black Plate, brown base – Very good bandwidth, bass, detail and soundstage,

CBS/HYTRON 6SN7GT, Black Plate, quiet and musical, the best of the non-military tubes

Ken-Rad6SN7GT, black base, bass a little tubby, but clean with great ambiance and air

Sylvania Green Label 6SN7GT, first top getter on the list, non-fatiguing, smooth, with good detail resolution and bandwidth, plus its easy to find and afford.

RCA Black Plate 6SN7GT, still a side getter, rich harmonic structure and maybe a little too sweet.

Sylvania Green Label 6SN7GTB, rich harmonic structure, good midrange, decent soundstage

General Electric Black Plate 6SN7GTA, the great driver tube? Fast, wide bandwidth, smooth sound at the expense of the of low level detail. Along with the Sylvania 6SN7GTB, a great “fourth” tube in Atma-Sphere amps.

Sylvania Green Label 6SN7WGT, Top Getter, “silver top” , very clean with great detail resolution and speed. Bass can be a little tubby and midrange a little congested.

6SN7WGTA, Sylvania black base green label, clean and fast with great drive, good bass

CBS-Hytron 5692, fast, good dynamics, lot of air and great timbre

RCA Red Base 5692, very warm sweet sound, great on voices and jazz

RCA 6SN7GTB, rich midrange, warm sound, likes being combined with other 6SN7 types, likes the Atma-Spheres

G.E 6SN7GTB, Gray plates, work horse, lacks refinement, a good tube

The VT-231 was the military purchasing and inventory control number up until about 1945 or so. The tubes were often also marked with the JAN-xxx prefix as well. It seems that the VT-231 number was dropped around the time the WWII effort was winding down.
But there was a lot of variation even before 1945. I have Raytheons made in 1943 which have only VT-231 marked on them, and the same vintage only marked JAN-CRP-6SN7GT.

Raytheon is CRP, Sylvania CHS, RCA CRC, CBS-Hytron JHY, Tungsol CTL, KenRad CKR.

It's also worth knowing that there is a common misconception about those VT-231 numbered tubes. It's nothing more than a number. If you find a 6SN7GT of the same vintage, it will be identical to the VT-231 numbered version. I have here Sylvania 6SN7GT from 1945 identical to the VT-231 numbered tube, and Raytheon 6SN7GT 1944 identical to the 1944 VT-231. Also RCA's, Tungsols, and so on. There is no magical significance to the VT-231 number. But some people think there is, because salesmen have told them so. It's become popular folklore in tube circles.

It's only so because VT-231 branded tubes are so common today, as the military kept thousands in warehouses collecting dust for decades until some bureaucrat figured out there was no equipment that would ever use them. The equivalent commercial branded tube was never kept in warehouses for decades, and in any event, most production of commercial tubes was severely rationed to keep war production up - so there were few produced with the commercial 6SN7GT branding.

还是一句话：相信三越就是少走弯路。支持！

没看明白老外的英文。
ken rad vt231听了几天，最终不想拿下来了，要比天梭NOS及天梭复刻要有味道的多，如果不比RCA5692差的话，就不想换了，本想出掉它买5692的。

反复换管子比较的直接结果——好几个手指被烫出泡！又要换皮了。。。。。。

呵呵，精神可嘉

df兄:欣見此帖重現,三越人有福了,有勞您了.
