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. 作者: modi 時間: 2007-2-21 21:35 標題: Re: 重料的300B後級 [quote:a7ae44b1e6="steve138"]Modi Sir,

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。未包膽作者: accphoto 時間: 2007-2-22 15:01
I had already complete one just before Christmas, See this

Very good! accphoto, how's the sound? Are you satisfy?作者: mbcy 時間: 2007-2-23 10:37
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作者: accphoto 時間: 2007-2-24 11:24
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. 作者: modi 時間: 2007-2-24 19:12

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！
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！ 作者: accphoto 時間: 2007-3-1 00:20
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.....作者: modi 時間: 2007-3-2 22:45
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！ 作者: modi 時間: 2007-3-2 22:48
今次所用的材料可以說是不惜工本了！ 作者: modi 時間: 2007-3-2 22:50
初型已經完成了，大家比些意見！ 作者: accphoto 時間: 2007-3-4 02:04
Modi Hing,
Where can you still get Black Gate 100u x2 500V ?
Thanks作者: modi 時間: 2007-3-5 20:24
