Tamang tama yan tutorial na yan sa paghinang ng 0402.

Tapos 0201 next 01005 hahaha, Rascal 0402 pa lang halos di mo na makita, galing naman!

hehehe ... itong hobby nating ito kahit medyo hirap basta masaya naman ok lang. Kakahiya naman sa mga mahilig sa hobby na ito kahit minimal alam sa electronics e kinakaya iyung pag hi hinang hinang. Iba talaga kapag inspired e

sir curious lang ako, ikaw, si sir ferds at others, by this time, are you all wearing eyeglasses with thick lenses na kakahinang ng mods?

Kasi ang mga Audiophile gusto may kinakalikot hehehe. Imagine nagpalit ka lang ng OPamp parang brand new na naman, I mean you need to review all your CD reference to hear the difference, next week mga capacitors naman, then mga resistor naman. Parang TT yan dami rin gagawin bago tumunog hehehe. Naalala ko 'yung CD palayer ko lagi nakabukas mga parts kasi installment dumating di ako makatiis haha.
By the way most of the audiophile grade na CD palyer purely manual like TT para marami kinanalikot.
More power sa mga CD tweakers, ingatan nyo lang ESD, make sure humawak muna kayo sa metal tube ng mga gripo nyo para ma discharge kayo when handling OpAmp or magbubukas ng player

Mawalang galang lang Sir DB10, hindi pa makapal iyung salamin ko

Ewan ko sa iba

Hindi iyung mata nahihirapan kung hindi ang mga kamay at katawan dahil minsan natutusok ng soldering iron o napapatakan ng tingga

Ewan ko kung bakit lagi akong may "urge" na magkalikot e

di pa ako bumalik sa store since nasira yung amp ko, pero balitaan kita kung makakapunta ako this week,
cd player pa rin ba gusto mo or speakers?

Curious lang po, puede bang i-mod ang non-tube na CD player into a tube cd player. Kung puede papaano.

si ferds batang-bata, walang gamit na glasses, ang bilis mag-solder!
kaliwa't kanan, soldering iron at yung pang-higop ng tingga (ano ba tawag dun?).

macdon · « **Reply #75 on:** Mar 11, 2008 at 07:27 PM »

Any comments on which current ss cdp in the market today is the most "tweakable"?

1. Marantz cd5001 (5th Ave)
2. Cambridge Audio Azurs (5th Ave)
3. Denon DCD500ae (Kinetic)
4. Tangent cdp -50/100 (Acoustic Dimension)

Desoldering tool ang tawag sa pang higop ng tingga.

Puwede iyun, tube buffer sa may analog output.

Then use Pb Free Solder para tuloy ang ligaya, medyo mataas lang ang Melting Temp kaya sometimes my reliability problem. Sa industry medyo nagkaproblema dahila ang mga semiconductor ready sa PB-Free pero mga board hindi yata. Pb Free are using High Temp Process

Already implemented - on electrical/electronic products going to Erurope, they should be RoHS compliant - this means that all mech and elec components must conform with the requirements.

Use Mundorf solder its lead free, with silver content and low melting. Problem solve

Mga sir,

tonong ko lang po kung saan ako makakakuha ng Fairchild soft recovery diodes? Baka may alam kayo kung saan.

Wala din po kasi akong alam sa circuits, pano ko po malaman alin ang output caps? Also, ang pagkabit po ba ng capacitors may positive negative or kahit balibaliktad yung paa ok lang?

Pasyensia na po walang alam sa electronics e.

Kung pang cd player, recommend ko ang Schottky 11DQ10 (100v/1.1amp). The best i tried and since been using for low voltage/ampere diode upgrade. Schotkky is better than ultrafast/soft recovery diodes.

Para malaman mo kung saan ang output caps ng CD player, trace mo from the interconnect output, the nearest cap. Normally ang gamit na output caps ay non-polar o pwedeng baliktaran ang kabit.

Thanks sir edwin.

thank you for the items that you sent me. Very smooth transaction.

How much would the Schotkky cost? Do you think we have it here? Might get a few more items from you. Just need to consolidate everything para hindi sayang shipping cost.

Thanks again.

Jason

Ano bang cd palyer ang balak mong upgrade? Maybe you could take some inard photos para masilip.

Will do sir, will email it to you.

Thanks.

Jason, my advise learn the basic of electronics first you must know the different Capacitors and their functions, this includes Diodes and resistor color coding (anyway if you have tester especially digital no need color coding heheh).
Then ask the experts here what are the components to replace/add which has great impact after tweaking. Below are my short list:

1. Change OpAmp
2. Power supply (diodes, Capacitors)
3. Upgrading the capacitors & Resistors (if needed) of the Audio circuits path of your Player

Soldering is also an important during tweakin, you might damage the board or the components you want to install/replace

Happy Tweaking

Will do.

One more question, do tube CDPs use op amps? Isn't it that op amps are used in SS?

thanks for your help.

thanks for your help.

In my understanding there are two types of Tube CD player: One is without Opamp and using tube directly into the audio signal and the other one is using Tube buffer, which are connected after the opamp these can be installed outboard like MF X-10D and X-10V3. Some of our friend here are making improved circuits of X-10D (DIY) or Tube Buffer.
If you still have space for your CD player you can put a CD buffer inside to minimize the use of Interconnects.
I believe Jolida CD player doesn't have Opamp while the Cayin, Consonance are using Tube buffer. Happy DIY'ng.
