一般的真空管壽命多少？
有什麼特別要注意的才不會不小心燒掉嗎？
一般都不會有問題
要注意不要摔到就是了
而壽命其實都滿長的....

小弟周6帶了 WA6SE 回家目前正愉快的使用中...
剛好看到這幾篇感謝各位的分享!
想請教2個小的管子(不知道正確應該叫整流管?信號管?功率管?)是RCA-6CY7....
跟另一個大的管子Sophia Electric 274B(不知道正確應該叫整流管?信號管?功率管?)....
想請教未來換管是否能提升?
提升的型號不知道各位是否方便建議呢...感謝!
前面大大說的WE 274B是否會比目前用的Sophia Electric 274B更好聲呢?
感謝感謝!

兩隻小隻的是訊號管，WA6SE上面應該"刻"的是6DE7(我的是這樣寫)，通用的有6DE7/6EW7/6FD7/6DR7/6CY7..不過台灣都很難買到
再來就是加轉接座玩不同管子，比較夯的有6SN7/VT231、6F8G，聲音一般來說都會贏上列管子
另外，信號管通常對音色的變化影響比較大
大的那支是整流管，可直接接5AR4/5U4G/274B，Sophia Princess 274B已經算不錯的了，再往上Woo的玩家很多人推崇EML 5U4G mesh或EML 284B mesh，價格跟Sophia差不多，當然，也可以接轉接座玩其他整流管...
至於管魔說的WE274B老管，找的到的一隻都要好幾萬，買來也不見得捨得聽....
小弟目前是Tung-sol 6SN7 BGRP加Sophia 274B(EML 5U4G mesh正在路上)，給您參考

因為head-fi上面壓根就沒人用過5AR4或是5U4G的老管.....
最好的5AR4是philips的鐵座...價錢約NT20k....
5U4G最好的應該是GEC U52應可在NT10k以下搞定...Goldlion印字的會比較貴一些.....
....................................................................................................
不說WE273B......5AR4或是5U4G都有點嚇人....畢竟5AR4/5U4G/274B是被炒熱的整流管
很多機器都在用...........................
唯一的方法就是先從便宜的古典管開始試.....例如5AR4的philips or mullard棕座
聽得好再挑戰鐵座.....當然....或許棕座就聽得很滿足了
至於現代管通常是聽2min....嚇到....甚麼鬼......
趕快關機拔下.....
........................................
附帶一題管子買來要趕快上機.....多聽個幾天.....
看有沒有問題........有些用幾天雜音或是甚麼的問題就會跑出來
甚至漏氣............
然後你就可以趕快退貨
不要捨不得用.....過了半年問題才跑出來
你的錢就扔到水溝了

WA6或WA6SE的主人可以參考一下..

OK... For You Tube Gurus...
OK... for all you tube gurus...
Which of the following do you most recommend for the WA6 SE+. I've ranked these in the approximate order of priority (given my research):
6DE7 tubes (better than 6EW7):
Tung Sol (Best)
Raytheon
Amperex
Sylvania
Philco
RCA
GE (Worst)
6EW7 tubes (not as good as 6DE7):
Tung Sol (Best)
Raytheon
Amperex
Sylvania
Philco
Admirial
RCA
GE (Wost)
Rectifier Tubes (other than the Sophia and EML):
5AR4/GZ34 (and related - Beter than 5UG4)
Tung Sol (and related Cetron/Chatham)
Raytheon
Mullard (Mullard and similar UK)
Sylvania
Philco
RCA
GE
Svetlana
5U4G (and related - not as good as 5AR4/GZ34)
Tung Sol (and related Cetron/Chatham - Best)
Raytheon
Mullard (and similar UK)
Sylvania
Philco (perhaps should be ranked higher - based on Jamoto8's experience)
RCA
GE
Svetlana (worst)
Of course this ranking reflects my preference for the rich, solid, tight, dynamic sound of Tung Sol and similar tubes - compared to more diffuse, leaner sounding tubes.
Any help will be appreciated.
Just doing some planning for my new amp.

*******Caution: jack of wooaudio has let it be known that recents units of the wa6SE
have differing parts, and may need a change of the cathode caps to make use of alternative
tubes like the 6FD7 and 6GF7A. make sure your amp has the cathode caps rated at 200v or higher.
some earlier wa6SE units may have cathode caps rated at 100v only. (change to 200v or higher
if you want to make use of the 6FD7 and 6GF7A)
the following rectifiers (input) and dual triodes (output) are compatible and safe to use with
the woo audio wa6 and wa6SE headphone amps. please feel free to add any other tube types
that are confirmed compatible, and are not listed below.
i was concerned about the high "mu" or amplification factor on some of the output tube types but
fortunately i've yet to encounter any distortion in SQ nor increase in floor noise. the increase in
"mu" definitely gives an increase in dynamics and soundstage. it should help those of you who
have a relatively low output power source DAC. likewise, if your DAC or CDplayer source has a
very high power output, you may encounter some noise or distortion with the high "mu" output tubes.
i use the vda2/vac1 DAC which puts out 2.25 vrms and did not encounter any humming.
i've been trying out the output tubes for the past 2 months and would've posted them earlier but
delayed it till i had a chance to receive all of those listed and gave it a good listen. i find them
more than acceptable and preferable to the 6DE7.
after about a half a year of using the 6sn7 on the wa6 and the wa6SE i've come to the conclusion
that the 6sn7 is a superb drive tube with an efficient power section too, at least with class A SET with
a output transformer. it's quite different than the 6de7 which is a fine dissimilar triode in itself. the
6sn7 is an equivalent dual triode that seems to present a larger sound-scape or arena without any
hint of compression nor edginess. the 6sn7 presentation is more refined and has an elegant sound
that will offend the least whereas the 6de7 is very dynamic with a U-shaped freq. characterisics.
for 70's/80's rock the 6de7 is great but with classical and small ensemble jazz the 6sn7's refined
sound hits the spot dead on.
RECTIFIERS ( RECTIFIER ):
*these must be at or below 3.0A
5U4G/ 5U4GA/ 5U4GB/ 5U4WG ( U52, VT-244, 5931 )

53KU
GZ33
GZ37 ( CV378 )
422A
274A ( with adapter )
274B *don't use chinese variance with 4.0A
DUAL TRIODES ( INPUT/OUTPUT ):
(#) = AMPLIFICATION "MU" FACTOR
no adapters are needed and these are
safe for use in wa6 and wa6SE:
6DE7 (17.5) - Fast transients, good for rock, pop
6EW7 (17.5) - Softer sound but slightly larger soundstage, good for some jazz, classical

if you want to make use of the 6FD7 and 6GF7A)
6CY7 (68) - between 6de7 and 6ew7
6DR7 (68) - similar to 6de7 but higher gain
6FD7 (64) - punchy bass, large soundstage, fast transients
*update: with homemade adapters one can make use of the following
dual triodes in the output section. for use in the wa6 and wa6SE.

6DA7/A - similar to 6ew7 but hard to find

6fq7 **** - same as above
6gu7 **** - similar to above
6gf7/A - higher gain with very fast transients
6cs7 - similar to 6ew7, good for string instruments

7n7 (loktal version of 6sn7) - same as 6sn7
ecc31 - higher gain, clear sound, less euphonic
ecc32 - similar to ecc31
6dn7/6em7/6ea7 - similar to 6sn7 but less refined highs and slightly higher gain
6bz7 - similar to 6ew7
6385/2c51/5670 ** - large soundstage, clear highs, slightly higher gain
6900/5687/7119/7044 - punchy bass, fast transients
7308/e188cc - very musical with refined mids and highs, slightly soft transients
6922 /e88cc *** - same as 7308
6DJ8 /ecc88 *** - same as above with different specs.
7DJ8/PCC88 *** - same as above with differing heater req. but works with softer transients.
6N6P *** very natural, open presentation, with slight warmth. equals or betters the 6922.
............. slight mid-bass hump present compared to 6dj8 and it's variants. great for bass lovers
6H30 *** very open presentation and slightly more dynamic than 6N6P
**this is only for wa6, with or without the pdps
(but not a direct substitute for the wa6SE. one way to use them on the wa6SE is to lower the voltage
to 150v at the anode plates and to raise the resistance to grid at pin 2 to at least 50 ohms to avoid clipping due
to the high gain nature of the amp and the tube itself. this is an amazing sounding tube that's comparable to
the 6dj8 family imo. this can be internally in the amp section or in the adapter with use of resistor at pin 1 (anode
of the power section) and pin 2 (grid of power section).)
***(must lower the voltage being supplied to the anode plate to 90v for 6dj8 and 100-130v for 6922/7308
in both wa6 and wa6SE. cathode resistance must be raised to 5.2k from 3.3k for the wa6SE only, to avoid clipping
due to high gain.) the 7dj8 has a 7v heater requirement but the 6.3 seems to sufficient as the sound is great.
the 6N6P and 6H30 can be used directly, with the adapter, without any resistors in the wa6.
low and high voltages to the anode section works equally well with the 6N6P/6H30 type.
applied 22 to 24 mA seems to work well.
**** the 6SN7 works fine on the wa6 but not so good with the 6SE. However, if you raise the cathode
resistance from 3.3K to approx. 4.7k,to avoid clipping, it sounds very very fine. i love this tube. you can
work with the resistance value to voice the amp to your headphone. playing with the cathode capacitance
will further refine the sound to your liking. the 6cg7/6fq7 and 6gu7 is almost as good as some NOS 6sn7.
it seems to be quieter than the 6sn7 in that there are zero mechanical or microphonic noise.
if you use black gate capacitors after the rectifier, make sure it's rated at above 200v. ideally it
should be at 350v.

大的那支是整流管，可直接接5AR4/5U4G/274B，Sophia Princess 274B已經算不錯的了，再往上Woo的玩家很多人推崇EML 5U4G mesh或EML 284B mesh，價格跟Sophia差不多，當然，也可以接轉接座玩其他整流管...
至於管魔說的WE274B老管，找的到的一隻都要好幾萬，買來也不見得捨得聽....
小弟目前是Tung-sol 6SN7 BGRP加Sophia 274B(EML 5U4G mesh正在路上)，給您參考
感謝各位大大的指教!有同樣的WA6E同好能互相研究小弟是第一次買真空管耳擴....
接HD800跟RS1都有很好的感受...為了HD800的耳擴實在傷神不少!!
不知道大大提的6SN7/VT231、6F8G音色變換影響大不知道換了是否適合HD800?這些在台灣好買嗎?(以實體店面來說..網路有點不太安心)
至於2748如果如大大所說還不差就暫時不換了...
謝謝大大指教
?P.S不知道大大的DAC是哪牌?訊源?最近也傷神這2樣說

最近也傷神這2樣說
我不是大大
小弟也是在七月份買了WA6SE才開始研究管子的，半年前小弟簽名檔裡的東西只有PS3...
我的訊源是Vaio Z系列，DAC是大陸貨，所有的東西都是這半年靠網路上的"二手資訊"堆起來的，雖然不是自己的親身經驗，但是看別人的分享多少可以省一點冤枉錢，小弟沒有什麼"換"器材相對的比較經驗，都是爬文後直接跳到可以接受的設備
目前為止除了HD800跟WA6SE本身，最沒C/P值的升級是Nordost Valhalla，最滿意的是Tung-sol BGRP，不過要用6SN7也是要費一番工夫
關於整流管，可以看看以下討論串
EML 5U4G Mesh Plate VS. NOS Tubes VS. Sophia Princess 274B Mesh Plate WA22

如果對WooAudio很有愛，這裡有三百多頁可以爬
Woo Audio Amp Owner Unite

不要一下跳到最後一頁，慢慢從頭看，才不會漏掉好東西

唔 這篇被推上來了
我是覺得你先找你想要提升什麼(如 人聲想更甜點 或者 聲音更凝聚點)
再來決定電源線比較好
我是用wa2 電源線是leemeeA7N,主要還是想再提升點透明感
另外官方有各機子的管整理可以參考

以前有根Woo Audio的Jack通過信
就他表示.. 不論早期晚期的耳擴, 6SE的小管子都不能用6SN7上轉接座...
只有WA6才可以... 其他還有6CY7也是
另外他們家最近推出新的轉接座, 可以上7N7. 就他表示也是比6EW7好的管子
ps, 印象中6DE7好像沒有比6EW7好阿? 阿災
總之我沒有問他為何6SE不能上6SN7就是了

截至目前為止，Wooaudio官網上，現在Wa6可用的真空管轉接座有：
1. 6DE7--->6EM7
2. 6DE7--->7N7
3. 6DE7--->6SN7
而Wa6se目前可用真空管轉接座有：
1. 6DE7--->6EM7
官網評論：
The 6EM7 is the ultimate driver/power tube for the WA6-SE. It has great extension and excellent clarity on all frequency range. You will hear each note with breathing air around it. The sound is smooth and well balanced.
This tube is compatible to the WA6-SE. NOTE: Serial number begins with 0410 is not compatible unless a modification is done. You will need to use a tube adapter becaue the pin layout is different than the 6DE7/6EW7. It is a twin triode tube with high amplification factor. It produces higher output.
另外6DE7--->6SN7轉接座，官網上賣的不適用於Wa6se。
Wa6se若要使用6SN7的話，除了等Wooaudio外，還可找美國Ebay上一位Glenn購買。
提供給各位用家參考！

現在使用Wa6se訊號管轉接座有兩種選擇：
1. Wooaudio官網賣的6DE7--->6EM7轉接座（附管，直接跟官網訂），價錢約3,500。
2. Ebay上一位賣家2359glenn購買6DE7--->6SN7轉接座（不附管，聯絡Glenn），價錢約1,500。
以上這兩種我都使用過，感想如下：
1. 6EM7管子的確比6DE7聲音好上一大截。在台灣6EM7管子價錢便宜，但是選擇不多、評論也少。若要換管調音色的話，只能自己購買嘗試...PS：Wooaudio轉接座超有質感！
2. 若使用6DE7--->6SN7轉接座，6SN7訊號管方面價錢高，但選擇性及相關評論也多。換管調音比較有依據可以參考。
以上兩種訊號管的聲音都比原本的6DE7聲音還來的好。
跟Glenn購買6SN7轉接座前，有跟他討論過電壓問題。
依據他幫head-fi上Wa6se用家製作轉接座的經驗，以及用戶回饋的訊息。
他認為使用6SN7管子的Wa6se，推力會較小，但足以應付大多數耳機！
目前我Wa6se用的訊號管是Sylvania 6SN7WGT，無任何底噪，然而推力的確比使用6DE7或6EM7管來得小。
這一小小缺陷，只需將音量調稍大一點即可！

所以除了6EM7和6SN7型號，其他6EW7等等表現都不如前述兩個型號嗎？
6EM7轉接座含管這樣價格是有考慮，但就如樓上說得，沒什麼心得可以參考，所以一直遲遲沒下手
6SN7原廠轉接就是沒下文，wa6版本出了真羨慕，樓上說那個賣家有看過，但印象看到有人買來有問題(運氣不好？)，所以不敢購入
目前是考慮買6EW7玩看看，但還是跟6EM7一樣沒啥心得。。。
好像台中沒啥人也有這台可以一起家訪交流..........慘
樓上是用A7N接這台管擴嗎？ 想徵都徵不到><
另外想問問Philips 5AR4跟274B比起來有啥差別嗎？老實說比較想換整流管，因為好像聲音變化比較大？

訊號管改用6EM7或6SN7的話，我覺得是有其C/P值。
以Wooaudio的6EM7轉接座（附管）3,500的價格，在音質的提昇方面，我認為購入是非常值得的。
畢竟光一條好點的電源線都不只這個價錢了...但前題是不會手癢或換換症發作...
品嘉那邊已有跟Wooaudio訂購6EM7轉接座了，可以電話詢問看看。
而之前沒一次購入兩種轉接座的話，只用Wooaudio的6EM7，我想大概拍賣所有的6EM7管都會被我掃過一遍
因為價錢上跟6SN7管比起來，真的是便宜太多了...
這應該算是使用6EM7的另種優點！
另外A7N的確是用來接Wa6se，Leemee的線材相對無染的特性，加上A7N通透度（空氣感）很優秀，接管機滿適合的。
因為不會影響到管機原本的音色。
Alex兄您也可試聽看看Lapi特製的管機用電源線，據說效果很不錯！
的確，換整流管的音色表現會比訊號管來的更明顯。
簡單說的話，整流管主導音色大部份走向，而訊號管影響細節的呈現。
打個比喻就像是交響樂團，整流管是指揮家，而訊號管是演奏者。
我沒比較過274B跟Philips 5AR4...
My-hiend有篇真空管討論，有274B、Philips 5AR4、5U4G的評論可以去看看：http://174.120.226.97/~leoyeh1/vbb/showthread.php?t=805
就我的聽感，Philips 5AR4還滿全面性的，不像一些整流管可能在人聲、Jazz、純樂器方面很出色，其它方面卻是普通到不行...
若是各種音樂類型都有接觸的話，我認為Philips 5AR4（Mullard GZ34/5AR4）價格絕對對得起它的聲音！

品嘉那邊已有跟Wooaudio訂購6EM7轉接座？？？
我明天打電話問看看先，謝謝提供消息
另外我想j兄問問那既然你已經買了原廠的轉接座，那對原廠3500附的6EM7管評價如何呢？
我是主要都聽女聲為主，所以整流管274B感覺夠用了(自我感覺良好。。。)

原廠附管是Westinghouse 6EM7，這管收到後我也上網google過，但評論少的可憐
就我本身聽感而言，跟原廠6DE7比較下，6EM7的確比6DE7好很多。
音場明顯大了一圈（用Rs1i的聽感，HD650感覺沒什差）、細節量也有提昇，但韻味倒是跟6DE7差不多。
這部份我認為可以透過換管獲得改善！
拍賣上GE、Sylvania、RCA 6EM7才1,200/pair，比起ALex兄274B整流管的價格，應該只能算是零頭吧
