Hôm rồi dọn, em có tìm thấy 1 cặp 12SX7 đã dùng, nó mờ chữ mà phải soi mãi. Bác nào cảm thấy hứng thú, em gửi tặng ah.
Ecc32 mid mạnh mẽ hơn nổi hơn tungsol hun khói mica tròn, bass ecc32 nhiều hơn và ù hơn tungsol, dải cao thì tungsol hun khói nhỉnh hơn chút,
Em đang dùng 3 quả này Pre brimar gt loại thân cao 4 râu phiến đen Hai quả symlavia đầu bạc tia chớp thân cao Các bác dùng rồi cho em xin ít rewiu với ạ
Tùy cấu trúc dàn máy và loại nhạc mà ta thấy bóng này hay dở ra sao. Theo mình bóng 6SN7 đầu bạc là ngon nhì bảng .Đứng nhất là bóng dành cho tàu ngầm - đã tuyệt chủng. Hiện tại bóng đứng nhất là Sophia Electronic. Mình không dám mua vì bóng này đắt quá .Xài đầu bạc là OK nhất rồi
Vs dàn em nghe thi đầu bạc đế sắt ko hợp. Nghe cảm giác rời rạc.. Dàn e nghe thằng 6sn7gt tungsol vs con cv1988 và ecc32 thi hợp.. Đúng la phải hợp vs dàn máy chứ so sánh vs phân tích đúng vẫn là khập khiễng
Em lấy tạm cặp cùi kenrad hun khói nghe thôi bác, Giá dc cắm thử cặp quả lê của bác nghe ổn là em máu đấy, hình như thấy bác đăng trên fb
Cụ cho em hỏi 6sn7w và 6sn7a của syly có khác gi nhau ko ạ.. E để ý cặp e có cầm la 6sn7a chứ ko phải 6sn7w nhìn 2 cặp này y nhau
Đây bác: LISTENING TO 6SN7s By Charles Kittleson and Eric Barbour’ © 1999 All Rights Reserved. - Mullard CV181 (ST shaped 1952). This is a very well-balanced tube. Great derail and very romatic with zero harshness. It also had very deep bass. An exceptional tube. Rating 97. - Sylvania 6SN7W (metal base ring, top getter early 1940s). An early type with a very smooth, well balanced sound. Presentetion was clean, but there was less gain than others. Fantastic detail, very tight/clean bass with superb accuracy. Rating 97. - Raytheon 6SN7WGT (brown base 1950s). Avery musical tube with excel-lent detail, hugebass, mid were very revealing. This bottle waswell-balanced and very fast. Consider this one a top perforrmer. Rating 96. - Sylvania VT-231 (bottom getter WWII era 6SN7). A well-balanced sound with good imaging and forward mids. Presentation was very smooth and musi-cal, but bass was a little weak. Rating95. - Sylvania 6SN7GT (top getter, black base early tri-plate 1950s). A musical and easy-to-listen to tube with sweer detailed highs. Bass was very good and imaging was excellent. Rating 95. - GE 6SN7GTA (1953) .A tube with nice imaging and romantic, satisfying sound. In addition, it had powerful bass and detailed, accurate mids. Rating 94. - Brimar CV1988 (brown base 1950s). Similar to the B65, but brighter and more detailed sounding. Rating 93. - CBS 5692 (brown base 1959). This one had about average detail, but better bass than the RCA 5692s. Gian was a little low, but it was fast sounding with very sweet mids. Rating 92. - Brimar CV1988 (brown base 1972). An excellent sound stage with a very satisfy-ing and musical presentation. Bass was not as tight as others, but still a top-rated tube. Rating 92. - RCA 5692 (red base 1950s). This tube had low gain and sumewhat weak mids. Detail was very good, bass was fat but indistinct. Transients were excellent. Rating 92. - Tung-Sol VT-231 (very, round black plates, smoked bottle 1954). This tube had lower gain, was sibilant, but was very detaied and had excelent hights. Rating 92. Conclusion.Without a doubt, the best sounding, most musical tubes in this test were the Sylvania 6SN7W (metal base 1940s) and the Brimar CV181 (ST shape 1950s). These tubes were exceptional performers in our listening setup. Unfortunately, they are very rare and can be expensive. A more readily available alternative would be either the GE 6SN7GTA (1950s). or the early Sylvania 6SN7GT (1950s). Later Sylvania 6SN7WGTs were not as “magi-cal” sounding as their earlier versions. Another great sounding tube is the Raytheon 6SN7GTA (1950s vintage).
