hmmmm, a screw adjustment aye, masubukan nga din, but i worry about master jojod's word of precaution....

what ill effect would it have sir jo on the cdp if ever?

thnx.

CDP owners should heed Sir JojoD's warning. I only make adjustments to my surplus machines na mahina nang magbasa since dito sa amin, "as-is" CDP is less than P1K, so kahit matuluyan okey lang!

somehow this makes sense, but choosing between dumping an alredy acting up unit or threading a dangerous and uncertain path to make it work as it was before again, well for me is a viable option.

whats life without a little spice anyway.

for afterall life is a game of chance and chances not taken.

Worse case scenario is you end up making your cdp so sensitive to vibrations or the other way around.

A more relative comparison is a car, cut it's suspension springs short (lowering) and you'll have a very uncomfortale ride, change it's spring with a longer one and you'll have a wooly ride and loose manuverability.

AS for sandawa's case, maliit lang risk nya since cost of surplus is cheap sa kanila. At least, di masakit sa ulo, natuto ka pa.

i completely agree, a once in a while risk here and there can be healthy.

However, when all goes downhill, just remember what you learned and you'll feel better.

syempre adjustment muna, pag di nakuha eh di bili ka na bgo surplus cdp tapos upgrade ng opamp, tube output, ano pa ba

?

biro lang, bka naman adjustment lang or dirty lens? Sandawa's method is what's used by a "known" audio center which uses water. Pero sila binabaklas yun buo lens assembly and nilulubog sa distilled water. Secret yan ha, wag ka maingay....

Bro kaya mo yan.. have tried that with my two initial surplus hehehehe and SUCCESS!! one time my cdp play all but for me somewhat slow ( reference is Onkyo grabe bilis ) kya open it up and saw some small knob and turn clockwise counterclock wise........ Alas.... pre di na nag read.. waaaa pero napa-read ko ulit!! hehehehe after 3 hours nga lang

odyopayl · « **Reply #579 on:** Aug 06, 2004 at 05:01 PM »

Reminder lang mga bro before making any adjustment (for experimentation or exploration hehehe) make sure you get a pencil or permanent pen to point the original setting so that if you fail or if your player becomes worst you can easily set it back to original configuration.

waahhhhh mahirap din pala.

reminds me of the time that i tinkered with my tvs internal setting, yon sa kakabuting ting ko medyo tabingi and upper part thereof sa display, but it becomes obvious only when the credits start rolling, ala credits ng star wars e.

Good thing about surplus CD players it's easy to make any experiment because of its price. It's easy to make tweak like changing capacitors & fast recovery diode on the power supply, next is OP amp which requires a little research for any direct alternative (upgrade). We have here JojoD & John & some experience fellow members who can help us. Upgrading CD players is really fun! Enjoy it while it plays hehehe!

Master Han,
Parinig din ng bago mo Toy!

Sirs,

A word of caution ulit, yun lens is also a laser. Kaya ingat lang sa mata ha, kng sabagay di naman kailangan na malinaw ang mata pag audiophile eh.

Update on the opamp tweak:

Been using a Burr-Brown OPA264 for about 36 hours staright now and the sound is opening up (at least to my ears). Low end is where it should be while the mids are, still very good indeed. But the most noticeable improvement is the highs which for me has been more detailed, fine and never harsh. This is what I expect since the new opamp is far more superior than the original opamp used. For me, the sound I have now on my cdp is for keeps, I may try other opamps out of curiosity.

Oh by the way... I did tried and biased the opamp into Class A operation and guess what, it sounded warmer! But I eventually went back to Class AB since the opamp biased in Class A is somewhat unnatural, for me at least.

Cheers!

We're being monitored by traders here in Davao/Mindanao. I went back to the warehouse where I got my CDPs early this week last Saturday and found all Sony ES and Onkyo CDPs gone. Marami sigurong na-inspire sa posts in JojoD! I recall there were about half a dozen Sonys below the 502ES models and two Onkyos (the 701 and 501 I saw didn't look good) early last week. A staff told me this warehouse supplies only by orders from shop-buyers. Maybe some read our posts regularly. I wouldn't be suprised if "tweaked CDPs" are sold by enterprising shopowners in the coming days!

sir jojo818 and all the tweakers,
Can I upgrade my DAC's CS8412 to CS8416?
How about the AD1862 (20 bit) of my DAC, upgrade version is AD1955 (24bit) can I replace it?

Is this available locally?

Thanks

A quick answer to your question is no, those chips are not available locally. I'm not sure if the dacs you mentioned are pin compatible, but even if they are, I don't believe that they can be drop-in replacements. Sorry.

Wow, if the traders of surplus gears out there are monitoring this thread then can you please give me a job? I am hard-working and willing to learn.

master jojod, dahil madalas naman ako sa davao (and eventually i'll relocate there), kami na lang ni sir sandaw taga-bili ng mga CDPs, then you be the one to upgrade the op-amps...hehehe!

If you have a shop there, maybe you could sell "upgraded CDPs" sigurado daming bibili na miyembro at lurkers. Otherwise, mauunahan ka ng mga enterpising traders dito who maintain two or three technicians per shop.

Sabi nga ni Superman, we can supply the CDPs you need. As far as I know, I could go below P1K per unit for you, Pantranco freight included (kahit mabulag kami, este, wala kita pala). Tapos yung mga masisira ko sa kalikot, ipapadala ko rin, sa'yo na!. What do you think?

Been to Crystal and Analog Device web site, they are the upgrade version and therefore pin compatible.

The problem is... you're right

. They are not available locally.

I don't see any problem if you can buy them abroad? Installation na lang problem mo pala.

Unfortunately, I don't have a shop. Anyway, if ever any traders here i Manila would ever come up with an upgraded cdp, it may demand a steeper price that can make buyers to stay away.

P1K per unit is very inviting to a lot of members here, sana nga lang pwede mo din test before you buy.

It's really cheaper here: P800 per unit "as-is" (plus P12 per kilo Pantranco freight if sent there). I've bought five "as-is" CDP units already since December, the last two without the help of a technician, and they all worked fine. Reason why I didn't offer sending units there is, firstly, because I'm relatively busy with my job. Second, the receiver of the units there should understand electronics otherwise, sa sobrang kalog sa bus baka kailangan ng adjustment dahil ayaw ng umandar. But if Superman relocates here and he's not busy, maybe he could do it like a true businessman.

Btw, one Jap surplus importer here has diversified into TV assembly. The brand is PJC (Phil. Japan Corp.) and price of "new units" - I guess chopsuey parts inside - range from P6K to P8K flat screen 25 to 28 inches (incl. widescreen). Parts and labor guaranteed 1 year. I was told the parts were NOS but I think only the tube, transformer and caps are new - the rest from dismantled boards of old Jap TV sets.
