重料的300B後級
請大家先看看這些材料，我相信會於農曆年後完成的，而且還會結合重料的前級，希望能有幾會給大家試聽。 :D
大家比些意見啦！ 嘩！ :shock: 真係好重料啊！
唔知那些料要多少錢呢？
隻千葉牛在港很少有得買，在那裡買的？多少錢呢？ :P
重料的300B後級
Modi Sir,How much for this kit set? What is the sound effect? All components are Japanese products except the coupling capacitors, will the sound trend Japanese style. I like British style. :D

Tango牛的質量很高，要比AN的普通牛更好，其本上不用擔心會是什麼聲底，因為最主要是要睇線路、交連電容等等。
這機是會比一名廠的Kit更好的，所以我不會擔心。
零件約$15000。未包膽 I had already complete one just before Christmas, See this

Tango Transformer, Blackgate Caps, Jensen caps and Jensen Silver Wire Very good! accphoto, how's the sound? Are you satisfy? hi~ would u mind telling me where to buy Jensen silver wiring?
thanks
and pls PM me the place and cost (price)
thanks thanks modi Sound very sweet, the circuit is based on Sun audio but modified for higher voltage on 300B. The plate voltage of 300B is at about 420V and running at 65-70ma current, I guess it is a maximum. Match very well with my TDA 300 speaker which needs only small power. I have MC275 and MC240 at home, I think it is better at least in my ear. :) Sound very sweet, the circuit is based on Sun audio but modified for higher voltage on 300B.

是否新做的呢？如是還要煲！大家要多些交流呢！
屏壓最高可以450V電流約75mA，不過420V及70mA是最好的，
唔知各下的output牛是幾ohm呢？如是2.5K會比較大的功率輸出，
至於陰極電流越大，聲音會比較厚，也比較溫暖，所以感覺sweet。
但300B很難同MC275 and MC240 作比較！ :D
Sun audio線路的電壓太低了，另外希望日後有幾會再用其它推動膽試作300B！ :D Yes, just do it this Christmas Holiday but the transformer was bought about 10 years ago and I had done a 300B based on WE91 circuit, using a WE310A as the driver. So I assume the transformer had run it a little bit but of course the cap needs about 100-200 hours run it.
I am using XE-20S and I have use 2.5K for the output impedence. My experience in my last 300B is that it is not powerful so I am using two Black Gate 100u X2 which seemed it make up the short coming of my last amp.
Just change to Full Music 300b/n this month and found the sound improve a lot when compare to China 300B,
Yes, we can share together on how to improve this amp as I like it very much..... 很快二月又過了，新年也過了，又要從新投入工作，新的300B要開工，今天用了約四個小時開頂孔，希望下次會快些啦，這部300B需然唔係我的，但係我希望能做到比我家用的300B更靚聲！ :D 今次所用的材料可以說是不惜工本了！ :D 初型已經完成了，大家比些意見！ :D Modi Hing,
Where can you still get Black Gate 100u x2 500V ?
Thanks Modi Hing,

Thanks
如想要可向william查詢。 再過一兩日便可完成了。
又會有機會試聽了，大家想唔想呢？ 此機用的錫線也是WBT啊！ Of course ! 完成了，今天開聲，還要Run in！
