| [#2] “梦幻之球300B” ??!! some people love it some don't and prefer other tubes, very personal taste. single ended 8W-10W per channel low damping factor, only suitable for high efficiency speakers or small room. if you use it with modern speakers with multi drivers and complex crossover, and you need to turn up the volume to over 70% to listen, then you will likely get disappointed by 300B. also you have to know different amps have different sound from the very same tube! if you really want to try 300B then the amp must be dual mono design, it not have to be monoblocks but at least each channel has it's own power transformer and circuit separated from other channel, this will negate 'crosstalk' and make the soundstage/imaging much better. use of chokes in power supply is a must. bad power supply = bad amp. I have a DIY 300B and planned to build a better one when have time. |

| [#3] “梦幻之球300B” ??!! 關西順位第一名是豐永靖宏的晶體機，輸出晶體是2SA1006B及2SC2336B。第二位是採8隻30KD6做輸出的真空管機，得獎人是原田憲二。沒有第三位，因原田憲二與豐田修二兩人並列第二。非常巧，兩人名字最後都是二，早知如此，取名原田憲一不就順位第一？豐田修二也是搞管機，輸出管是6G8B。---------- ______________________ 其中"豐田修二也是搞管機，輸出管是6G8B", 應為6GB8, 我也有玩, 係出色暨KT88. |

| [#4] “梦幻之球300B” ??!! Even same tube with also high efficient speakers , they will sound different in low hand or high hand player. Some people prefer directly heated triodes when they understand that music is not a competition for loudness. That said, a low watt amp can still punch your heart if applied nicely. |

| [#7] “梦幻之球300B” ??!! 個人玩 300b 推挽及單端機, 覺得最好就係聲音嬌柔, 聽歌仔或戲曲都唔錯. 缺點係:偏朦,慢,欠高音及狠勁沖擊.欠微絲細眼及空氣感 當然唔排除有人玩得好好, 現正尋訪中. 四,五極管有三種接法玩, 可jbl般豪邁奔放,又可tannoy般柔潤幼滑,乃各有特色, 未玩晒都唔知乜結果. 買一對貴價鐵座el34, 都係舊裝西電300b暨幾份一價錢. |

| [#11] “梦幻之球300B” ??!! 三極管絶對唔慢唔------ _____________ 就係聽過好多人咁講, 先覺得自己部機應有改善空間. 在此拋磚引玉, 就係想搵靈丹妙藥. 我幾種膽在同一部機, 同一系統暨表現, 令人疑惑. 或者高價300b膽會將測試結果改寫? |

| [#12] “梦幻之球300B” ??!! 要豪邁奔放或柔潤幼滑單是對300B是做不來,因應此膽的特性採長補短,全套器材配合得好定可做到. |

| [#14] “梦幻之球300B” ??!! 很多朋友都是像上述Ching這樣說,8火机点會夠力水,聽下歌仔就可以,但我用過不小三五極管,最後我都是留下3OOB,它不但高頻通透,其空氣感無人能及,中頻是比較清秀,低音是有線條那種,速度可以快到無倫,其次力水、厚潤主要取決於電源有幾足料,如果再加上不同時期的西電,取其各有不同韻味,是聽過世机種,特別適合horn. 線路簡單,胆又耐用,十年不變,再加上升值,是當今最抵用o |

I've one pair of WE300B 60's (no intention of selling them) bought 10 years ago. They sang perfectly with my Tannoy Silver driven by 864 + 26 direct-coupled directly heated triodes. Only a W.E. condensor cap in the simple monobloc circuit. I have also tried a pair of WE300A and WE 50's industrial 300B , the 70's and new WE retro and some other Russian, Chinese, Europes. We all knows the sound. Besides, I have AVVT. They're best to my ears other than the WE. I now listen to the smaller power type #10 (1 watt) and bi-amp with type #45 (1.5watt) without passive crossover on speaker system. I found these nothing loss compare with a single 8W triodes. Much fun and have never look back to pentodes for long term listening. |
