@opa_T komponen campuran, elco pan 2xFC 1000 uF,4xR generic,1 wima ,1 R semen, jumlah komponen 'cuma' ada 8 saja...menurut saya 3875 ini lebih melow (utk vokal lebih sip)dari kakaknya 3886 yang saya punya...(maaf agak OOT)

@mas yuda,
Setelah ganti relay, apakah masih ada dengung ketika power ON dan relay belum 'klik' ??

@mas sithot : ganti relay ke NAIS bikin relaynya ndak bunyi klik dan cuma muncul dengung. dan karena belom nemu BC517 akhirnya ya saya kasih 100nF di antara kaki B & C untuk BC546 yang sebelah kiri.
setelah dikasih remedy ini, ga ada suara dengung lagi dan langsung bunyi klik (tapi agak lama dink) soalnya saya pake 220uF buat kapasitor di bagian relaynya.

@mas terry:
muncul desis mas. soalnya trafo buat B1nya masih abal-abal. desisnya dari trafo kok. tapi sampai volume posisi 3/4 sih ga ada desis. kluar desis kecil kalo dibuka full.
udah pesen trafo dari LJ sih, cuma belum sempet dipasang aja. kayaknya kalo dipakein trafo ini agak mendingan tuh desisnya.
oh iya, desisnya jg berkurang setelah jalur ground di pcb B1, saya groundkan di box + resistor 10R/2W.

Yap, seperti yang Mas Yuda Bilang
Makin tinggi perbedaan tegangan antara INPUT dan OUTPUT
IRFP Bagian Depan (deket DIODE) --> Makin HOT.

Dan Makin Besar Arus yang dilewatkan --> IRFP bagian Belakang (deket Buffernya) Makin HOT

Jadi, monggo dicoba-coba sendiri. Mana yang sesuai dengan PRICE/PERFORMANCEnya.
