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. [/quote]
[quote:2357b596fb="accphoto"]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. [/quote]
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!
