Master Jojo, what OP-Amp you are going to install? Can you make similar to Browndog adaptor? I am planning to replace my Burrbrown OPA2134(Thru hole) (I hv the IC layout & specs) to AD 8066(SMD), once I replace it you can have my BB. My CD player OP amp are already socketed no soldering. It depends on you if you insist for an additional pro-fee hehehe!

sure sir! ikaw unahin ko dyan.

nauna na ako sa idea mo. kung sa tubes may tube sockets, ito may ic socket.

Pag oks na ito dalin ko sa bundok at magdadala ako ng mga opamps at ic puller para makapag opamp-rolling tayo.

uy! super hi-end na yan AD8066 ha. oks yan. i will look into it asap, kaso alam nyo naman ang problema ko eh, those requires miniature parts, eh ang lalaki ng mga daliri ko! Pasmado pa.

OPA2134 is the first on my opamp list to use in my Onkyo.

Meron ako nyan sir and other PDIP opamps that are considered to be high grade opamps.

Note that the pro-fee/talent fee I get is always re-directed to other projects and expenses related to electronics, for me, the challenge is what keeps me hooked. Di kayang bayaran ng pera yun makita ko na natutuwa kayong mga friends ko sa mga projects natin.

pwede rin ba sa generic dvd player na iupgrade ang op-amps?

pwede sir, pero i bet na smd parts na yan.

konti pa... konti na lang at bibili na ako ng wave soldering tool para dyan sa mga smd parts na yan at para ma-practice ko na. and dami na ninyo nagtatanong ng opamp upgrade kaso most modern cdp are in SMD packages.

FYI... SMD = Surface Mount Devices

ayan, may trivia pa.

iceman90a · « **Reply #526 on:** Aug 05, 2004 at 03:31 PM »

ilang project pa kailangan bago ka makabili?

eh kung patak patak na yung mga nakapila para maka bili ka na, he he he bawas na lang sa charge mo

john5479 · « **Reply #527 on:** Aug 05, 2004 at 03:39 PM »

OT: I think the first thing to upgrade with generic dvd players is the power supply, kasi kahit maganda yung opamp kung di naman nabibigyan na sapat na voltage it won't work optimally

btw jojod18: napalitan ko na yung regulators ng AA dac ko medyo mas mainit ngayon sya but the sound has become more open...natetempt na kong bumili ng blackgates hehe

Congrats on your upgrade john!

On the issue of psu, you are absolutely right, a good opamp is nothing without a good psu. Put excellence on both and you'll know it.

Sir Jojo, medyo sensitive sa ESD ang OP amp so handling is very sensitive make sure you are properly grounded before working on it! or hold on sa mga tubo ng gripo hehehe.
Congrats Master jojo nice work bravo! Hope to hear your short review soon!
BTW, no need to buy wave soldering OP amps are just 8 pins! kaya mo yan sir!
Expecting more tweaks on CD player!

Jojo, bilin ko dati ha... huwag magpapagod, magpupuyat at pabayaang basa ang likod... alagaan mo sarili mo, maraming nag aabang

odyopayl, sayang bat di ka nagpabili kay Bogsle ng brown dog adapter para sa AD 8066. I already placed my order for a pair of AD 8066 and the brown dog adapters. in 3-4 weeks time dadating na.

Surgery took a little over an hour....

The original Mitsubishi M5218 opamp on the right, and the SIP-8 to PDIP-8 adaptor card i made on the right.
