I have 2 days holiday yesterday, so I decided to continue my suspended hobby ;)

Picture below is the audio boards of my Toshiba DVD Player SD-2960 (most people will know this as SD-3950 or SD-3960 on America). I have modded the audio board by replacing three power supply capacitors for the D/A BB TI 1751 with ELNA Cerafine 47uF/25Volt. Two more coupling capacitors also replaced with ELNA Cerafine 100uF/16Volt. These two coupling capacitors (the two big with terrible layout) used to couple from the D/A to the op-amp (CHMC 4558).

Picture below is the audio board after the original capacitors was removed (before the ELNA Cerafine plugged in). Not a difficult thing to remove this capacitors, though I have some problem due to the hard-to-melt tin (the original tin was quite difficult to melt in this through hole PCB). So, I added some tin from my own (WBT Silver Solder) and let the tin melted together. Finally, my “tin sucker” sucked them all (I don’t know what do you call this stuff, but in my country, we call it a “tin sucker”).

Finally, the zoomed version of the D/A and the new capacitors. Poor layout there since the new capacitors (ELNA Cerafine) are quite big. If you want to know, the original capacitor is very similiar with the other black capacitors found around the Cerafine. See? Very huge difference in terms of size!

Don’t ask me the final sound quality. I’m too tired to put back the audio board inside the case. I will do it later. Anyway, I’m quite busy tomorrow. Perhaps next weekend is a good day to try ;)

    Nothing seems to be easier than seeing someone whom you can help but not helping.
    I suggest we start giving it a try. Give love to the ones that need it.
    God will appreciate it.

    Oom Jimmy,
    Saya sangat penasaran dengan mody ini. Pengen coba2 juga mody sederhana mirip seperti di link ini

    http://johnswenson1.home.comcast.net/~johnswenson1/3950_mod/Toshiba_3950_3960_mods.html

    , tapi sayang toshiba seri sd 2960 sudah nggak ada lagi dijual orang.

    Pertanyaan:
    1. Apa produk DVD Toshiba yang lain yang murah meriah tapi juga memakai DAC superior seperti SD-2960, atau sd 3950/60?

    2. Kalau SD 590AK apa juga bagus buat di mody? Skarang (2010)dijual cuman lima ratusan doang… padahal 24bit 192 kHz juga.

    3. Kalau di link di atas itu modif nya sangat simple. Ganti 2 capasitor coupling after DAC, langsung umpankan ke pre amp trus ampli. Katanya ini yang paling penting …. Jadi modifnya hemat sekali tapi sudah cukup superior.

    Apa komentar Oom JA?
    Terima kasih.

    Hi,
    1. Saya tidak pernah buka Toshiba yang lain, mungkin kalo ada yang beli bisa diintip he he he.
    2. Tidak pernah coba.
    3. Secara teori sudah cukup, tapi hati2 karena dengan membypass buffer internal, akan risiko kabel yang panjang akan membuat masalah. Pastikan kabel dari output DAC cukup pendek dan langsung ke amplifier. Atau berikan buffer tambahan.

    Thanks.
