[#1] 想造全牛交連前級    
想造一部全牛交連前級,牛入牛出,好像未見過有這樣的產品?不知道有沒有範例可供參考?

輸入牛用ISO Tango NN-6,交連打算用ISO Tango NC-20FII,輸出用ISO Tango NP-126

Thomas Maya好像只有牛入牛出前級,沒有用交連牛做級間交連?

Differential 10Y Line Preamplifier - Silver

14 silver wound transformers and coils

directly heated triodes ( ELROG tubes optional)

up to 4 inputs

SE (RCA) and BAL (XLR) in- and outputs

6dB gain

ultra low noice

very low output impedance (<200 Ohm)

transformer volume control, 24 2dB steps

two chassis (external power supply)

謝謝回應!睇晒都係無用交連牛做級間交連,只係用輸出牛做輸出,我唔係要技術討論,因為我唔識,會交俾專家代造唔係自己造,我只出概念,但我未見過有用交連牛做級間交連的前級(後級就有好多),唔咁知可唔可行?或者好唔好聲過用電容交連?

師兄為什麽有咁嘅構想呢?極大部份前级是無需要用推動牛,莫非師兄想用發射膽,做低倍數放大?

因為想試下全牛推不用電容的音色和其他效果有無唔同?發燒友就係咁痴線架喇,十幾年前出席過DIY瞻機網聚,有友師兄用自已撓的output牛前級,只是普通EI牛大大隻,一出低音和普通前級比好似貓叫和老虎吼的分別,原來用電容交連的膽機聽少好多嘢,仲未計斷絕共模干擾的好處,所以想趁現在仲能夠買到好牛試一試,現在好多牛如前Tango(ISO)復產,歐洲都有的唔錯產品,本土製作亦有一定水準,趁有得買就試試,Tango的老師父都七八十歲已經半退休,歐洲有間牛廠老闆話年紀大只接舊客,所以趁仲有機會想試試,好多Tango牛我等咗廿幾年先有得賣,唔可以錯過機會!以下是其中一間歐洲牛廠的通告,好大感觸 :

"I (Tribute Audio Transformers) have served the DIY audio community during the last fifteen years with custom winding all sorts of transformers. Most of the time these activities were fun, not only picking up challenges by trying to improve the products during these years, but also communicating with DIY'ers worldwide and discussing their projects. Being a very time consuming act however, and not willing to compromise quality, it has a downside too: too often lead times got out of hand, causing stress on both sides. Taking my age into account I did not want this situation to continue; I am 64 years now and when I slow down over the years to come I prefer to do it in a more relaxed way. Therefore I dediced to stop DIY custom winding within a couple of months; this means that I will serve my existing DIY customers as much as possible, but new customers have to look elsewhere. Priority will be given to my professional customers; they need reliable lead times. In that new situation there is less diversity in transformers which will make it less time consuming, more relaxed. I wish you all the very best".

我唔係想要無源前級,但有諗過在前級用牛volume,上邊貼間歐洲牛廠都有,但輸入maximum input 6 VRMS at 20 Hz太低了,我廿幾三十年前買嘅DAC輸出都十幾Volt.根本用唔到.

原來LUXMAN CL-1000前級就是用牛入牛出再加牛volume,看來我諗法正確,在高階音響所有電容,電阻都應該被電感取代,連最大功率的喇叭高頻衰減器到最細的前級訊號輸入都不能例外.

楼主可否分享点解想做全牛前級,是為其声音定只為其制作樂趣

每種牛都声音分別好大,牛出有理由但為何要牛入

先講牛入牛出,做個比喻你會容易明白的,城牆無論有幾高幾厚,只要有一個破口,敵人就會攻入嚟屠城,牛入牛出係做平衝傳輸,要由頭到尾都係平衝傳送先至有用.

依師兄呢個思路,如何處理電壓&電流放大,推挽方式,那麽單端功率级又可以點處理?

想請教用過 Finemet牛嘅師兄呢種牛嘅音色係點樣的?十幾年前網聚聽過好多次Amorphous牛,佢高音係好勁但無中音同低音,我接受唔到,但Finemet牛無聽過,的人又吹得好勁,如果好似加強版Permalloy牛咁都ok,但我都唔敢用佢嚟做後級,花咁多錢都係 Hi-B 牛穩陣的,因為一定唔會出怪聲,事緣日本ISO師父年事已高,肯同你做新牛已經好感恩,七八十歲老人家已經無乜魄力再開發新牛,現有嘅NP-126最佳電流只有5ma,有用家建議如要更大電流荷載可以兩牛並聯,但洗咁多錢咁玩法都係一種妥拹唔係咁過癮,除非有證據證明兩隻細牛並聯係好聲過一隻大牛咁又另計,差唔多價錢倒不如玩大的訂造過全套Finemet牛試試好過?

Jimmy兄
就#10你話十幾廿年前DAC輸出有十幾V
想請教是那一台
好像連balance輸出既都無10v輸出咁大
想請教一下去學習下

係有搖控volume的,唔記得型號了,我用嚟當無源前級聽咗成年咁耐.唔記得輸出10V定12V咁,老人痴呆無記性.

我見到有呢度之前有師兄分享英國C Core TVR應該應付到呢的高輸出DAC,所以打算加埋TVR入前級度.

好似係呢隻,但唔肯定係唔係吹呢個verson?因為佢隻隻Model都係咁款,有興趣自己研究下?留意版有Volume顯示燈係俾用家用搖控Volume當前級用,都幾方便.
