- #999 [vt75], 18-10-22 07:25近排有乜新裝靚聲 300B?
- #998 [vt75], 18-10-22 07:24請問用開的 300B 膽是 78mA, 如現換了的新膽是 60mA後,這需要調整偏壓嗎?
-----------------------
換膽一定要校偏壓 - #997 [i-walker], 18-05-26 08:31請問用開的 300B 膽是 78mA, 如現換了的新膽是 60mA後,這需要調整偏壓嗎?
先謝謝! -

- #995 [Timtube], 18-02-28 11:43請問除300B外,音色音質最靚的300B,是哪個?
Easy answer - 300A - #994 [sp11], 18-02-28 11:12請問除300B外,音色音質最靚的300B,是哪個?
——不明白這問題...
茄膽是否比葫蘆樽更好?
曾經問過謀歐洲大品牌的Sales,他表示沒有明顯分別,
只是有人買就有人造。不知是否屬實... - #993 [Hkhifier], 18-02-27 13:10請問除300B外,音色音質最靚的300B,是哪個?茄膽是否比葫蘆樽更好?謝意見,thanks.
- #992 [i-walker], 18-02-26 22:13謝謝 Yeunks 兄報料,等我找找先! ^^
- #991 [yuenks], 18-02-26 21:26i-walker師兄,你可到R-33二手市場search,先排有位師兄出讓一對Cetron 300B
- #990 [i-walker], 18-02-25 10:16小弟想搵一對 80 年代的 NOS Cetron 300B 膽,唔知有冇 c-hing 肯割愛相讓呢?
如有的話,可以在旺角交收驗膽
先謝謝! - #989 [bambino], 18-02-25 09:34#988
when we talk about standard 300B, i would think it's Western Electric 300B since it's WE who invented 300B tube.
Emission Labs has got 3 variants of 300B tube, namely 300B, 300B-mesh & 300B-XLS. As they are all 300B tubes, electrical property should be the same (i.e. same Plate vs Grid characteristic curve). The major difference among them is power handling which determines whether a 300B tube can substitute another.
Using WE300B spec as standard, it can handle Plate Dissipation up to 36W (although typical operating condition is around 22W). EML300 can handle up to 36W max which is same as WE300B. EML300-mesh max plate dissipation is 26W and that of EML300-XLS is 55W. In this sense, EML300 is considered as a typical 300B version. EML300-mesh is a low-power version but built for a different musical taste. EML300-XLS is a high-power version.
Whether a 300B tube is compatible with a power amp is determined by plate power dissipation set in the amp. It's determined by manufacturer when they design the circuit. If this value is lower than the max plate dissipation of the tube, you can safely plug it into the amp. If they are close, tube life will be shorter. Having said that you need to know how to measure plate power dissipation set in the amp. If not, it's safe to use standard version, in this case, it's EML300.
hope it helps

但根據廠方資料300B mesh不是用來直代standard 300B的。請參閱以下網址。
這裡大把師傅,可幫手講解說明,因為我也想了解一下。謝謝??
如師兄對用300B mesh有疑慮,可用standard 300B / 300B xls。

SP11師兄,請問EML-300B 是否可以直代其他300B的呢?
即係用 EML-300B 需要改零件值嗎? - #986 [sp11], 18-02-23 09:12新到的EML 300BMesh開唱了約20小時還未完全開聲,但朋友和我也覺得很有WE 300B的味!從容不逼⋯
而Elrog 300B則更通透,音場更深和闊,全頻來得實牙實齒。 - #985 [Antonylun], 17-10-12 14:34對這對有何評價?
- #984 [munhon], 17-10-12 13:54Hi,
Just had the chance to do a A/B comparison between PSVANE 1:1 replica and Takatsuki. The setup used ALLnic integrated amplifier and DeVore Fidelity Orangutan O/96 loudspeakers.
Takatsuki - Airy, emphasis on lush mid range, very good for vocals, little bass.
PSVANE 1:1 - Good sound stage, balanced tube, tight bass, good for instrumental jazz - #983 [伏喱哩], 17-09-15 13:59各位DIYER高手,
如祗有本級負回輸,輸出沒總回輸。
輸出端牛的0,4,8,16歐姆的0歐姆有需要落地嗎? - #982 [bcyw8328], 17-09-13 19:28各位Ching,(二嫂) K03x最新價錢?請pm.Thanks.
最後修改時間: 2017-09-13 19:29:54 - #981 [bcyw8328], 17-09-10 09:59各位Ching,( 二嫂)k03x及k05x,sacd機,評價如何?請指教,Thanks.
- #980 [sp11], 17-09-08 00:13其實器材都是講求配搭,不論是個別一部膽後還是一套系統。曾經有位師傅講過,線路決定了聲音的取向及質素,而零件是錦上添花,使器材有更佳的發揮。JCV和Cary都不是大牌子,但都是認真設計兼用優秀元件的廠家。
