WINDWSS is using GE5670, i also bring 1 unit WE396A to him for testing, he also notice the diferrent, i think if put on your Jensen copper sound will be much better.

hi, superwhite,

Thank you for you information.

I have suprise toyou. I made a black colour picture paper on the CD. (Same size with CD) the sound from my speaker should be solid, clear, 3D.improved much.
costs = no costs.
You can try it or give comment.

Thanks you.

Hi Viewer,

Really? o.k, will find black paper n try it.... :wink:

i have 1 more thing to ask, what series good for cd player?( i mean vishay or vishay BC Component) i saw so many series on FARNELL, dont know what to choose..... :?
SSWONG 發表於 2006-10-22 23:22:04 | 顯示全部樓層
Hi viewer and superwhite,

Actually there are another alternative instead of making a black paper disc use on the CD, if u have old disket, open it and take the black manegtic thin sheet inside. it will give similar effect and much more easier than make it, nowaday most of the disket is 3.5inch, if u can get the 5.25inch one will be bettre as the size similar as the CD. But becareful, must remove thorougly the glue if not it may stick on the player tray.

The main fuction to to reduce vibration so sound stage become clear, less noice. If u willing to spend then can just buy this type of damping mat but not cheap loh....

Viewer,
Need some advise from you, do you think evox-rifa cap is better or wima (MKC4)is better or RIFA PHE 428? If use for tube coupling cap...


superwhite,

I now so aggresive as u thus i now ask friend around to get me some un-use circuit board n try to retreat useful cap. A lot medical equipment is using cap such as rifa, wima, nichikon n so on. Anybody heard of ERO cap (KP 1836 E5)? good or not?

Hi Viewer & superwhite,

Intially when i change my 6N3J to GE jan5670w, feel that GE sound very sweet, warm & nice but a bit slow & not so detail --> good for vocal but bass less tight, musical instrument also less excited. Since i prefer intrument like drum and so on, thus i some time change back to 6N3J when listen to musical instrumnet then back to GE when vocal.... Generally i will say WE 396 is overall good, sweet with detail thus no need to always change tube while listen to different song/music. compare the GE, WE396 is less warm & sweet but more detail, faster. GE tube construct is a way that it reduce the detail in order to give very warm & sweet sound.....

Hi Superwhite,

vishay or vishay BC Component for ecap are good (euro sound) warm and sweet.

Hi Windwss,

My Das is using a lot of RIFA PHE 428 caps, the high notes is clear (good).
I have no use Wima MKC4 before, so no comment on it.
But I used Wima MKP10 and Wima Black Box before. RIFA PHE 428 same of Wima MKP10.
Since Wima MKP10 is high grade than MKC4 so RIFA PHE 428 may be better than MKC4. I think.


Thanks for sharing.

hi viewer,

Thank for your info, as i know the MKC is metallized polycarbonate cap, it seems it is more expensive material than polypropene and have good electronics characteristic but i'm not sure good for audio use or not as i since most people like to use polypropene cap. MKP or MKS is the replacement for MKC as MKC no longer manufactured.... but i'm just thinking some manufacturer sometimes stop production of some product is to reduce cost with reduce a bit the quality. So sometimes latest version may not be better.... so in audio u think poly propene or polycarbonate is better?

Superwhite,

Ha... i not so ambitius and willing to spend like you... thus i look for other alternative way to look for parts loh.... by the way u 12 DIY a tube preamp not i got a DIY diagram using 6n3 & 6N11.....

Ah forget to tell u that i got some info on modify audilab 8000A which is to seperate the pre & power of the 8000A.....

Hi WINDWSS,

Tube pre-amp? not this moment, wait until i finnish MOD my CD player first, bcoz, if DIY Pre-amp, also need lot Budget, same thing like cd Player,
i want better sound, that why i spent some money to buy good component, you dont want after you Built the pre-amp, sound is worse than your AUDIOLAB, then no point to DIY the Pre-amp, also i want to Mod this cd Player to the MAX then only MOD my AUDIOLAB amp........ :wink:

So when you want to MOD your 8000A ? :wink:

Thanks for the diagram, if Tube pre-amp i Prefer to built CV3

Hi viewer,

want your help, what resistor is good for MOD my CDP? Metal Film or Wirewound? do we really need low tolorence like 0.1%? is our resistor GOOD? After change some KIWAME resistor sound Good, warm n sweet, but they dont have 0.5W resistor.

Thanks.
 樓主| viewer 發表於 2006-10-25 13:03:27 | 顯示全部樓層
Hi superwhite,

Over 0.5w is no problem, I also replace the resistors behind the tubs, to 1w.
If you want changed to 0.1% tolorence resistors sometime be good but price is high.
e.g Vishay box style (black colour) 0.1% tolorence resistors but very expensive = HK$170 each. (Very good).
Your present  resistors is very good la !!!!!!!
Is the KIWAME resistors are 1w??????

I suggest you don"t upgrade many times. because the IC will be esay shorted or locked. becare !!!!!!!!!!!!!!!!!!!!!!!
Your present cdp is very good la!!!!!!!!!!!!!!!!!!!!
If you changed opa to 627am that the sound have great improve.

Thanks.

:wink:

Hi viewer,

Cant really find the 0.5W resistor with 0.1% tolorance, only can find 0.25W , is this suitable? maybe go for Holco(maybe only)

i found the Vishay box resistor also, around that price also but dont have the value i want...... if have also not going to change(Is too expansive)

Thanks for sharing!

P/s: you still Mod your CD Player? any News? :wink:
 樓主| viewer 發表於 2006-10-25 13:51:15 | 顯示全部樓層
Hi superwhite,

because CD33 is tube cdp so I think use 1W is better. because CD33 is original 1W. in outup and power supply.  or ask the diy shop.

Now i have no mod my cd33 now, I enjoy its music. because its soun is suitable for me.

thanks.

Hi viewer,

sorry, i dont have any comment on it, but for lot of FORUM said, still the NOS is the best, RCA is NOS should be better than GE, why not try WE396A? cant get WE396A? if you really want some tube SOUND really different, my advice is WE396A, if not like my DIY shop Always said" here good abit, there good abit, after all only good abit" after all only good abit, but you have pay 2more tube price.    try WE396A my advice..... :wink: if you feel that this tube not suitable, you still can sell it same price or you post to web n sell it,very good price. (most of shanling owner want this tube)

Hi superwhite,

Vishay is belong Philip now.
Black Gate is the best e-cap in the world, go-ahead to change Black gate even standard serise should be better that vishay te serise. Just the price is higher that others. Same as Jensen and M-cap.

Just my view.

do you agreed??????

Hi viewer,

I actually look for JENSEN b4 mod my CDP, but after i search for long long time cant get the Jensen here, the only similar is Audionote Copper PIO, but according to DIYSHOP said, this cap got 1 problem, shorting when use in 300B amp..... , so he recomment my the MUNDORF S/oil, so i have no choice, to buy this mundorf, is still cheaper than AUDIONOTE.

Mundorf sound is more DIRECT, FAST n  DETAIL. more on natural.

Jensen is more sweet, warm, also detail.

what you think? i actuall can said is FORCE to buy Bcoz NO choice :cry:  :cry:  :cry:

but will try on audionote soon......
 樓主| viewer 發表於 2006-10-25 15:12:51 | 顯示全部樓層
superwhite,

since then, no need to change to audionote. because it is expensive than Jensen but not same to jensen. don't waste money.
If present upgrade is suitable for you. Enjoy the music la !!!!!!!!!!!!!.

1) the filter in between power coupling cap got noise when the power cord on but the switch on/off button at cdp still off. Is it cap problem?

2) the 3 opa wrtitten on the board is OPA2604 but on the chip is 5532D JRC, is it the same?

Hi WINDWSS,

Great, you CDP have Potential to MOD, What is the value of Power filtering cap (red colour)? first get the power done...... then go for tube output..... if your red colour cap is 0.22uf, maybe i can lean you my solen cap.....
SSWONG 發表於 2006-10-26 17:39:45 | 顯示全部樓層
THE POWER FILTERING CAP (red pinky colour) is WIMA MKP 10, 0.1,1000-600

the 2 Power coupling cap (coklate) is 220nJ/630V
superwhite 發表於 2006-10-26 17:47:56 | 顯示全部樓層
Below is Bada HD22, you can see all cap is using SOLEN. you can just follow the modification or change something better than solen like mundorf or jensen(dont think can get) sound should be improve.... :wink:

even power filter cap also solen.

it cheap n easy to get....
:wink:  :wink:





if you really need to Mod it , first you need to know what output you prefer, Tube or solid stage. if you like tube sound, can just MOD the tube PART.

Hi windwss,

I have used SCR Solen and  ERO MKP 1845
SCR solen quit balance.
ERO MKP 1845 bass ,high notes are little  clear than solen SCR
old solen don't use.
ERO MKP 1845 have green and blue colour. Blue is better than green on high notes (smooth)
Your present CDP is using SCR SOLEN or SOLEN ???????
I thing the solen caps in your cpd not real good.


Thanks,

Hi windwss,

refer to you cpd photo, the outup cap changed e-cap Elna slim grade.
Why? flim cap alway better than e-cap very much.
I really don't understand.
I have suggection to you:

replace the all the caps to SCR SOLEN low cost and high gain.
If you want the high notes better. can add Wima Black Box 0.01uf/400v or 0.1uf/400v on SCR Solen. the result will give you suprise.
If you use ERO MKP 1845 cap no need to add other cap on it.
You cdp's caps are old solen.
just my view.   low costs high gain.

Thanks.

Hi viewer,

sorry for interrupt, the WINDWSS cd player is BADA HD21, not HD22, so it totally different from Bada hd22.  n actually WINDWSS haven't MOD his CDP yet. ALL STILL ORIGINAL. :roll: that why he is asking which cap to change.
