1. Beli bahan PCB yang Fiber (lebih tebal lapisan tembaganya..)
amplas yang halus trus dicuci pake sabun
dan siapkan layout yang sudah di print terballik pake kertas bontak..

2. Panaskan dengan setrika tekan dengan kuat agar proses transfer baik sekitar 20~30 detik

3. Hasil proses transfer selesai

4. dilanjutkan dengan proses etching Fe3cl + air panas sekitar 40~60 oC
kurang lebih selama 15menit selesai

5. Setelah proses etching selesai baru lubang-melubangi... untung sedikit komponennya klo banyak pegel juga heheheheh..


setelah selesai melubangi

6. Bersihkan toner yang menempel pada PCB disini saya pake TCE, bisa pake thiner ato lainnya.

hasil proses pembersihan toner

7. Kemudian proses penyolderan komponen..(resistor dlu, kemudian capacitor/elco, diakhiri IC), Elco nya pake merk Panasonic

tanpa LM3886T dan dengan LM386T

Tambahan Gainclone untuk LM 1875... (soalnya penasaran blom pernah denger hasil suaranya klo yg 3886 sebelumnya dah pernah buat tahun lalu metal)

Lapor:
Tadi malam ngoprek GC LM 3886...
1. Ganti trafo abal2 dg ERA 5A 25 volt.
Dicoba suara bertambah jelas dan mantap bass lebih deep...lalu
2. Elco PSU ditambah Nichicon low profile 25000 uf 50 volt paralel...seperti saran mas Ady...hasilnya mantap tenan... jauh lebih jernih dan bass improve banyak...
masih blum masuk box, baru motong aluminium di bengkel kantor ...
thanks

Good Luck upgrade GCnya mas Arif

kalo masih mau mainin psu (kuncinya GC), coba :
tambahkan C russia pio K4*** bypass di ujung psu
atau tambahkan solen (or audiograde) 3,3uF bypass catu + ke - sebelum kaki pin suply IC (Carlos v.4)

btw, mudah yah mainin bass pd LM3886
kalo bikin high lebih halus, gimana pd 3886 ?

Groundingnya paling tidak seperti ini :
[DIY & Share] Gainclone LM3886 & 1875 PCB - Page 14 Lm1875

atau jika Gnd sinyal di angkat :
[DIY & Share] Gainclone LM3886 & 1875 PCB - Page 14 Lm1875lift

so'ir kalo layoutnya jelek, ngasal gambar aja, yang penting routing Gndnya paling tidak seperti itu.
Yes Sir
