freezone2010 link=topic=2612.msg24071#msg24071 date=1290682306 Wrote:Saya lihat2 ada power yang ada rangkaian lagi dan ada tabungnya. Disitu disebutkan berfungsi sebagai buffer.
Apakah rangkaian buffer tersebut menggantikan fungsi pre amp?
Mengapa yang saya lihat menggunakan tabung untuk buffernya?
Seberapa signifikan penambahan kualitas suara jika menggunakan buffer?
Apakah perlu trafo khusus untuk buffer?

Mohon pencerahan para pakar. Maklum masih newbie dan hanya masih bisa nyolder2 aja meski kadang keliru nilai komponen yang harus disolder.

kalau gak salah pasti benar, buffer itu sbg penyesuai impedansi i/o dua stage.
