First topic message reminder :

Dengan tidak mengurangi rasa hormat saya buat rekan/suhu2 di SF Ampun , ane bikin nih B1 dari skemanya bung la ode (sorry mas saya copas layoutnya hehehehe)
soalnya gak sabar pengen disandingkan dengan 2 gainclone ane..

ini versi murahnya bikin PCB buat para newbie kaya ane yang kebingungan mo bikin PCB lol!

1. Seperti biasa siapkan kertas bontak dan print layoutnya terbalik (ane pake PCBexpress)

2. Siapkan PCB yang akan dicetak yg terlebih dahulu diamplas dan dibersihkan agar toner merekat kuat, disini saya pake 2 jenis bahan PCB berbeda yang Fiber dan biasa

3. Proses penyetrikaan (nah ini yang perlu percobaan agar dapat hasil yg maksimal bagi yg baru coba heheheh)

4. Selanjutnya proses etching dengan ferricloride secukupnya & air hangat kurang lebih selama 10mnt, sambil nunggu Merokok dlu..

setelah selesai hasil etching diberi lapisan timah biar gak korosi

Nah ini yang bikin kantong pada bolong Smile
belanja komponennya.. elco smua pake panasonic,
[DIY] B1 buffer pre-amp PCB - Page 18 20091125110221_DSC03325_4b0cac4d190c1-t

5. nih hasil nya sebelumnya setting / trim dahulu potensio linearnya untuk mendapakan voltase di 18VDC kemudian bonding dah tuh potensio biar ga muter2 heheheh

dah dicoba ke ampli biasa pake trapo 2A 24V good sound dah, next mo disandingkan gainclone lagi mikir mo jadi satu pa terpisah enaknya... and ganti Resistor ma yang lbh bgs.. :bounce:

thanks buat rekan2 SF smua... go DIYers........... metal

mo coba juga pake hifi pre-amp dari esp product.

Itu relainya yang berapa volt? Coba di tes pake tegangan langsung, buat ngecek yang rusak relai atau delaynya

brati ada yang salah kali ya ? soalnya harusnya relaynya tetep 12V.
ada tegangan yang drop dimana tuh ?

Mas yadi, coba turunin lagi v-out dari caps 220uf, kalo bisa +/-VDC 10-an volt, sesuai design shunt reg salas.

Benar kayanya ada tegangan yang drop, di trace belon ketemu R yg mana?
barusan relay ga dilepas langsung ditodong disetrum pake adaptop scanner 12V 1.8A, bunyi klik2

7812 nya harus dicek, biasanya keluar cuma max 12,5v

klu keluar lebih tinggi harusnya relay bekerja , masalah bukan di IC tapi 2 TR dan R yang terpasang, coba ganti TRnya atau pake BC548 2X

Okeh ntar senen mau cari BC548 dan R, R nya ukuran berapa dan untuk menggantikan yang 47k atau 10K?

Waaah kykny kl solfegio ngadain kontes BT buffer B1 nya seru banget kl yaaa......
Dari berbagai macam model pcb n beragam pemakaian komponen d tampilkan, berlaga guna mencari maksimalisasi suara buffernya..... He4x

Elco 120uf kanan atas = 10.2
Dioda 1N4002 = 6.27

Pertanyaan:
1. kenapa led kanan atas agak redup
2. Relay tidak bunyi "klik", tapi mendesis setelah 6 detik

Mohon Bimbingan, apakah ada penempatan komponen yang salah.

Salam,
YADI

- Tinggal bermain2 dengan LEDnya (pasang LED BRIGHT di V (kanan/bawah)
- MMM, akhirnya ada juga yang kena "CHATTER" di Relaynya.
DI forum luar sana, dulu ada 2 orang yang kena juga.
MOnggo diikuti saran Mbah SALASNYA

"That was a remedy for those without a Darlington like BC517, when some prototypes showed some erratic NPN relay driver and relay coil ''chatter'' mishaps. A 0.1uF to 0.15uF cap across B,C of the NPN under the coil could shut down the coil buzzing, soldered underneath and directly to the NPN's pads, hidden from view. No further report of chatter was mentioned after specifying BC517 relay driver. If you just happen to have a BC550 for that or other, the 0.22uF cap will still save the day if you chance on an upsetting relay coil. The 7812 is the 3 terminal 12V reg for the delay and relays. "

biar cakep sengaja saya pasang led hijau semua di salah satu rail dan led kuning semua di rail yg lain, mungkin itu penyebab perbedaan tegangan antar rail ?

@yadi

Saya belum layak dipanggil OM Smile

SIP PAK, monggo pakai yang nonpolar.
atau diganti aja sama BC517 u TR bagian kirinya (kalau ada) tanpa psg caps --> PREFER.

hehehe, makasih kang CRT, relai udah bunyi klik, diukur di diodanya dapat 12.3V, setelah diganti ke BC517, cuman apa gak ngaruh ke suara nih kan asalnya BC546

Rekans,
Beberapa hari lalu saya melakukan upgrade shunt reg B1 buffer.
Pertama ini :
[DIY] B1 buffer pre-amp PCB - Page 18 Dsc00396tk.th
Hasil (versi pribadi) : Mid dan high makin kinclong, makin open,makin detil, bass juga makin bulet walaupun tenaganya rasanya gak berubah. Thanks ya mod ady.
Trus yang kedua ini :
[DIY] B1 buffer pre-amp PCB - Page 18 Dsc00397zm.th
Hasil (versi pribadi)
Nah caps ini sy pakai buat ganti Cs yg 3300uF, hasilnya luar biasa nich caps. Sy suka 'ces-ces'nya karena makin panjang dan bersih. Suara juga makin mak plong. Thanks ya mod ady.
Trus yang ketiga dan keempat ini :
Diode 1N5819 (schothky) ke MUR120
Relaya (biasa) -> NAIS
Hasil : udah agak lupa, tapi jelas memberikan improvement scr significant.
[DIY] B1 buffer pre-amp PCB - Page 18 Dsc00398u.th
Keseluruhan upgrade diatas bikin suara makin mantab di low, mid dan high.
Rasanya sich sistem diatas dah bisa menandingi 3F kaleng full BG punyanya saudara.
Sebetulnya ada 2 caps 330uF yg belum di upgrade, enaknya pakai apa ya ?

tq
