穩陣...睇你點為之穩陣
我未試過香港買, 不過我諗在香港會比較"穩陣"地買到你想要的膽,較不易出現"面與內容不符的情況, 不過價錢就吾係好"穩陣", 可能會比人"搵笨",
而外國site 就相反價錢"穩陣", 內容可能"搵笨"

    Hi, Jadis, sorry for late responce.
    I did do some searching on web before I reply you(lukily I found some articles about 6SN7 also wrote by you...haha), according to yor suggestion, you mentioned that I could try replace two of the default 6SN7 by GP CV 181A and try the result of different positions, I am wondering if I replace all four 6SN7 of my Melody Super34 by GP CV 181A, what will happen??

如無記錯, DA50S的12AU7是負責前級訊號放大, 放大後再經12AX7作推動級給功率管, 此時你買的大盾1 ...

    "12AU7 Mullard longplates, square getter, 1950s vintage, Great Britain. VERY RARE.
New Old Stock White Box and original box. Some shield logo types, some are the old white label pre- shield logo version. These are all the older long narrow plate version, with the rare early SQUARE top getter, with the 1950s date code. These are incredible tubes with a fine soundstage, clean top end with a touch of midrange warmth. Rare. Good stock now but fast vanishing!! MATCHED PAIRS, ARE $295.00 PER PAIR."

Fullmusic 6SN7 x 2 pcs
RCA NOS 6SL7 x 2 pcs
主要聽人聲，要厚暖有韻味。。。。

Mcleo 兄,
   我建議你先分開試6SN7目的是想看那個位置對聲音委的變化更大, 再考慮比重位置, 舉例先買兩支 RCA5692/6SN7, 用在不同的位置哪兒較靚聲一點, 例如是中間的兩支, 那麼再買 CV181A 時, 就插進這位置, RCA5692/6SN7 改為用在一左一右位置。當然, 四支 CV181A 會對聲音幫助更大, 音色會甜入心肺 ...
