These are the exact tubes used in the Sony c800G which has been confirmed with Sweetwater. The Russian tube smoothens the high end frequencies, add a slight boost in the 500hz range (which was lacking in the original French tube). It also eliminates that high annoying frequency around 3435hz range that users have experienced.

2009年5月18日 · 当然,它们的声音音色是有些区别的,我以为这两只小七脚管的声音以细腻见长,而两只大八脚管以声音温暖为主,其中大八脚管6J4P的声音不可小瞧,我曾将它接成三极管同6J8P作比,在低频的松软度上它比6J8P更胜一筹,同时其音色一样优异. 帘栅极接到阳极,抑制栅在管内接到阴极,或者在管外接到阳极 (在管内已经接到阴极的,在管外就不要接到阳极),这样得到的便是一个中放大系数的三极管. 对于这样小功率的电压放大管,它的帘栅极可以直接连接阳极而不用通过一个 …
