向樓主請教,不知採用了甚麽方法,來減低它的microphonic呢?

All voltages are correct, waiting for the circuit to warm up and stabilize then to set the desired distortion characteristics

Finished finally. This is making the ta2020 amp in the bedroom setup sounding like a tube amp now, what an eye opener!?

3 silmics are used in both channel and they are right on the signal path.... High, mid and bass extension is pretty good but when playing tracks containing acoustic bass, it would sound somewhat lose and boomy at times.... could it be because of the silmics? Polypropylene caps are on the way so I shall find out soon

Aging第三天,bass的looseness 和boomieness 不見了,順耳好多,現在可以immerse在音樂裡!這幾天所用的後級是lm3886,imaging相當好,所聽到的,的卻是膽機聲,但就缺了一點三極管的creaminess吧

R33會員中,用家多,DIYer少,相關帖的確是比較冷清的。不過,DIY從來都是一個比較個人化的嗜好,可分享的成分比較少,我相信真有熱誠的DIYer,是不會介意繼續發表的。
