sir hans,

galing lang ko cubao kanina, wala pa mga bagong talents 

si hans naghahanap ng bagong mga talents. 

[JojoD818]

yehey! finish na opamp adaptor pcb ko!

[JojoD818]

di ko na natiis, pati drilling and soldering nilamay ko na. 

[H a n $]

BGA,

sir thanks..

JojoD,

Sipag mo ah iba talaga pagsariling unit sarap magexperiment..

[Audioboy]

sir i tried it pero i have to use a long extension cord dahil napakaingay nun vacuum cleaner. nun pinakinggan so far so good! 

mukhang natyambahan ko ah 

 

good job.

[JojoD818]

BGA,

sir thanks..

JojoD,

lalu pa gaganda (at least, sa tenga ko) yun tunog ng cdp ko pag na install na yun. 

[akyatbundok]

jojo, ako una sa pila dyan ha pag sawa ka na sa tweaked onkyo CDP mo hehehe.

pwede ba gumawa ng iba-iba nyan para pang OPAMP-rolling?

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!

Sir sent you PM

[wanderlust]

masta jo,

cge sir, keep you posted nalang what ever comes. as i said i have 2 of these korean amps both at 1000w powers.

congrats sir, sipag at tyaga ano. kabit mo na para madala at mapkinggan na namin next session.

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.

you mean "korean trafos" right? 

experiment muna natin yun cdp ko, pag successful then sunod ko na kayo. 

[iceman90a]

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

[JojoD818]

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]

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]

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

[wanderlust]

yes sirry....

ok yan sir as i am more intrested then with the result of your cdp quest than all the other projects i have in mind.

hahaha, ganda idea yan ah. pag nakabili ako nun magaaral na din ako ng cellfone repair! hehehehe

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. 

[JojoD818]

yes sirry....

ok yan sir as i am more intrested then with the result of your cdp quest than all the other projects i have in mind.

actually i'm prepping na for my cdp surgery....  medyo nervous lang ng konti... first time ko sa cdp eh. hehehehe

[kid]

hahaha, ganda idea yan ah. pag nakabili ako nun magaaral na din ako ng cellfone repair! hehehehe 

wag na to sir madami ng may alam nito, sa audio konti pa lang hehehe
papila din sa cdp ugrade ha

[john5479]

jojod18: You can borrow my soldering iron hehe

[odyopayl]

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!

[iceman90a]

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

[audi0slave]

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. 

[JojoD818]

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

naka ilan palit nga ako ng sando sa cdp ko na ito, pinagpapawisan ako! 

[JojoD818]

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.
