opa 627bp in MHZS cd33

Hi viewer,

I got some doubt need your advice, pls refer teh picture attached. I'm also wondering why the manufacturer use the Elna Simiic ecap on this position. It is 100uF/50V. On the board it didn't write any value of uF shld be use, so can i change it to other type of cap (poplypropene & son on) with smaller uF, what your recomendation? I don't think we can get any polypropene cap with 100uF.

Besides, is LXF ecap better than rubycon?

os-con is ok la !!!!!!!!!!!!!!!!!!!
Black gate very expenvise.
be-care the de-solding and solding.

Thanks.[/quote]

Hi viewer,

Thanks, after all, think will change all cap to BG, (see my budget) :

Will borrow my friend De-solering gun(Air vacuum) should be o.k, even my board i have change ALL my steel jumper wire to pure silver wire(0.3mm). :wink:

Hi viewer,

planing to change the all 100uf 16V rubycon cap, any suggestion?  Black Gate STD or Sanyo OS-CON SP series better?  :wink:



Thanks!

I have no experience on TANTALUM ecap. so no comment on it, but i found that many expensive cdp use it.
I have one dac, it use some on ditigal part. I think it is suitable on digital part.

Hi viewer,

Thanks alot...... :wink:

Hi viewer,

Thanks for info,

do you know anything about TANTALUM ecap? is this suitable for hifi? how can no one is talking about this cap?

Hi superwhite,

Vishay MKP 1845 cap have two styles (box and tank)
have green and blue, same of ERO MKP 1845 cap. beacuse ERO is belong Vishay BHC = philip compamy.


Thanks.

hi windwss,

I suggest use at least over 20% of your country's voltage.
I agreed superwhite said his resistor (ceramic resistor) to KIWAME Carbon
2W is good and cheap.
Diy not = high costs. just what sound you want base on costs.
so many brand of caps. you can try each by each. just diy fun.


Thanks for sharing.

Hi WINDWSS,

i have change the resistor (ceramic resistor) to KIWAME Carbon 2W, sound great. it only RM5/pc

Thanks for sharing. :wink:

[quote:1014f1dc02="viewer"]Hi superwhite,
Vishay ROE MKP1845 n ERO MKP 1845 are the same technology.
ROE famous on ecap.
ERO famous on film cap. (GREEN COLOUR and BULE COLOUR)

What colour and style on ROR film cap (box style) ???????

Hi viewer,

Sorry for Late reply. Great! the Vishay cap MKP1845 is AXIAL type, is a Matelized polypropylene film, but i dont know the colour.

Thanks! :wink:

yes, it is on your phto but is 275V not the 250V.

my country use 230V...oh..too bad... if i still want to use it what's the worse case? cap burn only or will affect otehr parts?

if this cap better than MKP 10?

I had attach 2 photo.
1) shall i replace those gray resistor?

2) photo 2 is the cap i have in hand at the moment, which but i'm not sure it sure suit to be use in which area?
a)ROE 470uF,40v
b) Philips 47uF,250V
c)shizuki 0.47uF +-10% 200v
d)EFD PR3, 0.1UF +-10% 630V
E) NIPPON CHEMI CON , mallory & some spprague cap

Hi windwss,

what is you country's votalge????
if 110v no problem.
if 230v, i suggect at least 400v will be safe.


thanks.

hi windwss,

Is this cap:

HI,

Need advice from u both.

If i got WIMA MP3-X2, 0.22uF, 275VAC but the VDC not mentioned even they test on >2000VDC for 2 sec.

Can i use it to replace my 0.22uF,630V power coupling cap?

understand thant WIMA MP3-X2 seems higher grade than MPK-10.

Besides, can i replace the WIMA MKP-10, 0.1uF,1000-600~ to WIMA MP3-X2, 0.1uF, 250VAC?

Hi viewer,

just need to know any different on the Vishay ROE MKP1845 n ERO MKP1845 is this two cap share the same technology? if for ERO i think can't get, only have VISHAY ROE MKP1845

Thanks!

Thank you viewer!!

i think i will try for ERO, low cost high gain... : )

hi windwss,

You say have noise when you on th cdp, it may the the problem on black colour Boxs which close to RCA outop. it may fixed not well or burn.

upgrade may replace all flim caps to ERO MKP 1845 claer sound and lower costs. result quit good.
if no costs problem you may replace m-cap (Supreme silive iol), muiltcap (RTX), jensen (copper foil) and Muscia cap. subject your tasts.
costs around HK$600 to HK$1000.

opa can changed to 2604, lt1057, opa2134, opa 2111, ad827, dy2000 pastic package
cost around between HK$25 to HK$100 each.

thanks.

[quote:0f5c2e1cb4="viewer"]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,[/quote]

Hi viewer, as superwhite said my cdp is still original not change any component yet pls refer the pic HD21 which i attached and not the HD 22 attach by superwhite.

the original component at my HD21 is as below:
1) power coupling cap -- 220nJ/630V (ceramic cap??)
2) power filter cap?? WIMA MKP 10, 0.1uF,1000-600~
3) tube coupling cap --> EVOX 2u2J,400
4) single cap beside the tube is SOLEN MKP-FC 0.1uF/250V
6)OPA --->5532D JRC 5014c (but on the circuit board it written as OPA2604AP)
7) most of other E-cap is rubycon

So what the recommendation?

Superwhite,
u r order the opa from HK right? it the supplier have 2nd hand OPA 2604?


Thank you!

Hi windwss,


opa 2604 is better that 5532 (JRC) (Japan radio company) very much.

opa 2604 all ranges are better. sound like tube.

price 2604 is HK$25 to HK$30 second hand
        5532 is HK$5 brand new.

thanks for sharing.

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.

Thanks for sharing.

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 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,

Found some good stuff in FARNELL, VISHAY ROE MKP1845, price also cheap, but dont know is good compare to SOLEN? :wink:

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.

Just sharing :wink:

THE POWER FILTERING CAP (red pinky colour) is WIMA MKP 10, 0.1,1000-600

the 2 Power coupling cap (coklate) is 220nJ/630V

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.....

hi,

attach the pic of my cdp.

some question:

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 viewer,

Thanks, but the jensen price compare to audionote price here not much different.

Hi superwhite,

$230.00 each in authorised dealer.

Hi viewer,

How much HK selling 0.22uf 630V Jensen copper PIO, i know there is 2 type of CuPIO?

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 !!!!!!!!!!!!!.

Thanks.

[quote:2534371bb1="viewer"]Hi superwhite,

I do't understand that if you want warm and sweet sound,why you used M-cap. Its sound is face to clear ,  bass not the best. In my view I will prefer use Jensen pure copper foil cap.

do you agreed??????

Thanks.[/quote]

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......

Hi superwhite,

I do't understand that if you want warm and sweet sound,why you used M-cap. Its sound is face to clear ,  bass not the best. In my view I will prefer use Jensen pure copper foil cap.

do you agreed??????

Thanks.

Hi viewer,

o.k so 1 have to change my plan..... :cry:  but is o.k, bcoz i want musical sound not digital...... :wink:

(if blackGate have to come out more budget already..... )

Thanks bro!

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.

Thanks.

Hi viewer,

I plan to change it to VISHAY TE series, bcoz all CAP using VISHAY



is this suitable, or black gate N better?

Any idea on TANTALUM cap? good?

hi superwhite,

I have suggection to you on your cdp photo enclosed which point out e-cap.
I changed it to Black Gate Stand e-cap. the sound have improved

It you changed it to Black Gate Non-polar e-cap same uf same valtage, that the sound will be more improved. but the costs will be higher than balck gate standard e-cap more.

Hi viewer,

Hope you won't regret, :wink:



Hi WINDWSS,

How your progress? your TUBE arrived? any modification on your CDP?
Hope got good news. :wink:

Hi superwhite,

Thank you so much.
I will try it.


Thanks.

Any comment on RCA 5670 tube compare with GE5670, WE 396A or others.

Thanks[/quote]

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)

my 2cent :wink:

Just sharing

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,

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:

Hi superwhite,

Any comment on RCA 5670 tube compare with GE5670, WE 396A or others.

Thanks

Hi superwhite,

Normally resistor for cdp 1/2w is enough.
higher no problem.

Thanks.

[quote:f7cd2cd2ab="viewer"]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.[/quote]

Hi Viewer,

o.k, Thanks, just that i buy the capacitor n 1 short buy also the resistor.

the KIwame only have 2W, but the size same as 1W.... no problem replce 1W with 2W.

the OPAMP still not arrived on DIY shop maybe have to wait 2 more week.

:wink:

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.
