opa 627bp in MHZS cd33

Hi WINDWSS,

Hope you like the way it poison you :  :  :

actually i'm been poison since 3 month ago, so just take care, dont let the poison run your whole body, you will die very scary, :wink:

Hi windwss,

In my view, i feel ERO MKP 1845 is much better than WIMA MKP 10.

ERO MKP 1845 let the sound clear much.
the costs of ERO MKP 1845 0.1uf/1000V  is quit cheap for 2nd hand market in HK within HK$15 each.
Of cours,Jensen is the best. but very high costs.

Thanks for sharing.

Hi,

i totally agree with viewer, if really got budget, go for jensen or audionote, bcoz i feel this type of cap really can SING!!!! i'm using AN copper in oil now, it really sound more better then my MUNODRF silver oil, the different on the MID improve, more natural n sweet. :wink:  :wink: WINDWSS, try it! you will be poison the second time......... :  :  :

Viewer,

Good then i can get the new ROE 1845 at Farnell only at RM 15 (~hk30)...

Hi WINDWSS,

viewer,

Hi windwss,

I think High notes will have great improvement.

please let me know the result.


Thanks.

Hi superwhite and windwss,

Have you feel the heat problem in our cdp, when it play around 30 half hour, because tube is provided a lot of heat and the cdp no holes.

So i have made two holes 1"on the top of CDP33. the problem be solved.

Thanks for sharing.

Yes, my cdp also quite hot after long hour playing.....
u ope hole at top or back side??
why not just take out the plastic/glass on top of your CDP?? YOUR CD33 have a transparent glass on top of the tube right?

Hi viewer,

me too hot, but no choice, have to use small fan to blow the cd player, if hot. for me it not practicalif open hole on top, bcoz my house got alot of dust, i cant make hole on top, if make also will make side of the casing :wink:  

Hi WINDWSS,

the cd33 is different from cd 55 only on the glass on the casing. viewer 1 without the glass.

the the ecap you want to parallel is for the TUBE VOLTAGE reservoir right? do you think parallel it will give much effect? To supply voltage woh, if you parallel the cap, i scare got side effect, hope you dont try it.... if you want to change to new cdp then can have a try :wink: And it is not a signal side. :roll:

Thanks for sharing

Hi Abhader08,

Where are you? Missing in action? Or kidnap by alien? :wink: JOKE
Why so quite? just come on this sat to MOD your CDP, the BG cap is ready :wink:

i don't think putting a 0.022uF will have much side effect...no harm to try : ) if die then die loh... can learn more trouble shooting skill..... mistake make us to learn more!

Viewer,

Sorry to disturb u again!!

unfortunately MKP 1845 only have small uF, for large value like 2.2uF and above only MKT 1813 is available.

Do u know any sound diffrence between  MKP 1845 & MKT 1813?

Besides, if use as cap for speaker cross over is the MKT 1813 (polyester) beter than solen old cap (PB-MKP-FC)?

hi windwss,

ERO MKT 1813 sound is quit good, clear but MKP 1845 sound is smooth than MKT 1813.
MKT 1813 (polyester) is beter than solen old cap (PB-MKP-FC) I try both before.

Thanks for sharing.

thank you viewer...then today will go made some order...

hmm just receive my new panasonic audio grade ecap...

look good...but sound don't know lah...guess shld be better than FC

Hi windwss,

I think may not better than FC, because the e-cap should be other package.
so colour have different, i think this is normal e-cap. The leg of this e-cap not as copper with tin.

Thanks.

VIEWER,
Don't know oh, since in the farnell manual it written as audio cap & is new cap ..but u r right, it is not copper with tin layer....

dear viewer,

If not mistaken the FC i bought previousely, the leg also not copper with tin layer......

the fc with leg of copper 7 tin layer is old version if not mistaken....new version maybe had "偷工减料“

Hi WINDWSS,

nice colouring of your panasonic cap, :wink:  hope this can get better result. just MOD my audiolab 8000S, to all BG cap, need time to run in first, hope can have better result, n for the CDP will start MOD tomorrow, only that will post some PIC. :wink:

Thanks for sharing

superwhite,
yesterday i help my fiend to replace 3 BG cap into his audiolab...so difficult, his audiolab's hole is smaller than mine, the position also very close to corner.....take me >1hr to make the cap pin smaller n so on...


viewer,
do u know what's the function of the feroid fluid in the speaker drive? i had check my friend's tweeter, the coil inside is ok and it have sound too. only problem is the sound volume is ~30% of the other good 1..... do u think the feroid fluid amount will affect the volume?

Hi WINDWSS,

mine AUDIOLAB also small hole, that why i use 0.5mm silver cable to joint each other, after change all pre part to BG N series, sound improve alot, on vocal. :wink:

SUPERWHITE,

Why don't u open a new title "Modify audiolab 8000S/A" in this forum?

superwhite & windwss,

i am looking for a used audiolab 8000c, 8000s or 8000c + 8000p. can you help me?

after i done a major mod. of my cdp, the vocal is beter now. and i found that fc cap really can not be used at all, the new eca is much more bater then that.

i have an idea of change my speaker also, anyone of your friend is interested? price can be discuss.

later i will also post some pic of my cdp for you to share. merry chrismas.           

aharder,

u had use the Panasonic eca?? i had just install in last night, seems acceptable....

dear all,

my mkp 1845 just arrive today...will try it out soon....

had replace the wima mkp-10 with roe mkp 1845, the improvement is good... more detail but not harsh, more comfortable sound...so as viewer said it is really a low price high gain cap.... suitable for people we like acceptable improvement with low budget.

Hi superwhite and windwss,

I solved the heat problem with my MHZS cd33 for you sharing.
The photos are enclosed;


Thanks.

photo 3

shifu Viewer,

u DIY the hole or ask the shop to do it for you?

By teh way need your info, have u use the LCR film & foil capacitor? is it better than the ROE MKP1845?? since it is film & foil.

Hi windwss,
I did myself.

You sd LCR is it should be SCR.
I think it can not be better than MKP1845 in my experience.

enjoy you listening la  !!!!!!!!!!!!!!!!


Thanks.

Viewer,

the picture is the LCR cap is it manufacture by SCR? but it is USA company oh!

i don't have the tools to make hole on metal part ops:  ops:  so can't do as u did.....

superwhite,

u seems to disappear???!!! :evil:  :evil:

quickily take the photo of your modified audiolab and post it in with new title!!!!

Hi bro viewer n bro WINDWSS,

Very busy this week, as got final project n sales need to push, sure will send some PIC, sorry. :wink:

Viewer,

Need your info:

1) In Hk, where to buy cheap black gate? 鸭己？女人街？ or ocative?

2) I heard Jensen ecap also not bad, where to buy? which model is good?what's the price different if compare with blackgate standard?

3) my audiolab amp got a lot evox mmk cap, if i wish to cahnge it, what't teh recomendation of replacement? ero mkp1837?(box type) mkp 1845?

ROE MKP 1837 or MKP 1845 anytime is better than evox mmk 8820 right?

Hi windwss,

1) In Hk,  don't ask where is cheap of Black gate e-cap, I only buy it from two places only: there are the dealer of black gate cap.
1.www.soundexplorer.com
2.Burch electroic co. in cental district of HK.

2. Jensen e-cap only one model just e-cap.  The sound of  Jensen e-cap is sweet than black gate. but black gate's bass is better than jensen, up to you. Price of black gate standard is cheap than jenaen.

3. I suggect use ERO MKP cap, its sound will be better that evox mmk.

These my suggection, hope to help you.

Thanks.

thank you viewer & happy new year!


superwhite,
My friend now in HK, if not mistaken he will meet william today (he 12 buy the clone 1sc). He will buy me teh Jensen reservoir (10000uf) for my audiolab too... my audiolab age ~15yrs i believe the reservoir cap almost "gong/die".....

Dear viewer,

have u compare teh balckgate nx-hi-q small cap to teh mkp or mkt or solen cap? how's teh result?

e.g 0.47uf/50v BG hi-Q have small size, it is easier to get than other 0.47uF/100v mkp/film/foil. Can a BG hi-Q ecap sound better than mkt/mkp/film&foil??

dear viewer,

any idea of the sound quality of Vishay sprague 735P (metallized polyproprene cap)? is the cahracteristic similar to roe mkp? since in malysia roe mkp only very limited choice of uF. Only mkt 1813 have more choice.

If 735P is better than mkt 1813 then i will use 735P. Since polypropene is usually lower dissipation factor than polyester(mkt).

windwss,

I am now having an Audiolab 8000A MK2 integrated Amp, it's look diffenrent compare to yours. Any idea which path or cap should i mod to improve the vocal. Now my hifi set totally changed to cd33, audiolab 8000A for pre, audiolab 8000P for power, QED 25th silver anyversary speaker cable then Rogers LS7t. I am very satisfied at this time. just see is there any cap for my audiolab 8000A. pls advice. :wink:  :wink:  :wink:

superwhite,

busy people also need to have some fun time, just relax we will be having a perfect plan soon. don't force yourself too hard, every succeed people also had their difficult period. your sincerely.        

dear all,

anyone know  which op-amp replacment for cd33 are better beside bb opa627, i read a review said that Analog device also having a very high quality op-amp but don't which model.

Is your audiolab mk2 similar as photo attached? s/n: start with 2, then got a flat cable.
since u got 8000p u can do another trick ---> separate your 8000A to pre & power by removing 2 resistor so that the pre & power inside your 8000A will not connect internally. (I got info on this call or email me for more info).

then change the ecap in pream side ~8-10caps only (all to BG) cost ~rm150. u will see a lot different a lot detail. twisted the cable of the output to RCA and twisted the inner powre cable. Since u have 8000P so no need change BG cap in 8000A's power amp side (~4caps)

if still not satisfy and wish the audiolab vocal slightly warmer then u may change the EVOX mmk polyester cap (tatal ~40caps) in pre amp &power am side to other better cap. (i will do this soon but i'm only low cost high gain so will only change the evox to ROE mkt for better detail & natural sound.... if u want better then may look for some tin foil or cu/oil but will cost u a bomb. my audiolab got ~8pcs 0.47uf, 6pcs 0.33uF evox cap...

Hi, Abhader08,

You can try Analog device AD797 AH(Metal package) its sound compared with BB 627 AM (Metal package) is 人聲及中頻會好一些(有味道)但低頻都是 BB627AM好一些(低頻变及質感) up to your tasts.
I have used both in my MHZS CD33. finally I chosed BB 627 AM.
because CD 33 is tube cdp so is very match BB627AM's sound.

Thanks for sharing.

Hi, Abhader08,

Analog device AD797 AH(Metal package) and  BB627AM both the top class op-amp of these company.


Thanks.

Hi all,

i'm back finally, but i still haven't take some PIC for my CD33, sorry ops:  But dont worry, will be up laod some PIC soon.

Hi  Abhader08,
Thanks brother, as you know have to work hard, so that can have more money to MOD  :  :  : , anyways thanks for advices :wink:

superwhite,

Finally u r back!! if u still not "pou tao" i'm thinking to post a "WANTED" poster for you!

dear all,

since my friend mr. superwhite already install bb627 into his cdp, i planned to try the ad797 for something diffenrence because with my audiolab 8000p 100watt per channel + rogers ls7t the low frequency was very good already. but i still haven't check is this op-amp can be found in malaysia or not, hope that mr. windwss can help me to find out  please.
i have an idea to use my audiolab 8000a to drive the HF and audiolab 8000p to drive the LF i had this advice from a hifi chop sifu he said that this arrangement will provide better detail and live field, please advice.
i don't plan to mod. my 8000a until i finished the cdp mod. i still have a few path in cdp need to be mod.

windwss,

i had comfirmed my audiolab 8000a is MK2 it come with the white ribbon and the volume control also better then ver 1, it is square type. you mentioned that your friiend will help you to bring back the jensen 63v 10000uf ecap from HK, can i know the cost for this ecap and do you believe this is better then the original one. if so can u pls help me to buy also. my 8000a is using 2 units meanwhile the 8000p is using 4 units.

        

aharder,

Ya, u can do bi-amp, 8000A drive HF & 8000P drive LF, then u won't waste the 60W of 8000A than if u use it for pre only.

whether Jensen gold is better than original Elna black negative? i'm not sure. Maybe other here like viewer can tell.

I can tell is that the charcteristic of most jensen is sweet sound and my 8000A almost 15yrs old, no matter how the big cap is going to die soon as i can feel the degrade of it's performance... my friend will help me buy from william. the price is ~HK210/pcs u can check the price in hififever.

Most probably i will receive the big cap during CNY, then i will able to tell u the performance. After CNY he will go HK again then back in May.
Since u no hurry on modify audiolab, i suggest let me test & see the result in CNY then only u decide whether to buy or not.

Another info, spend the same money on mod audiolab seems have better result than cdp.

for audiolab, u just need to replace the 3 cap (100uF/35v) near power supply already can see a lot improvement. Imagine ur 8000A is ~10yrs old, estimate it been use 3hr/day, 10yrs-->10,000hr so most ecap nearly die....


hey, if u change opamp can sell the old 2604 to me? as i'm not going to change to 637 or any upgrade... if i will do any upgrade in future i will try to bypass opa.

dear all,

my 8000a mostly equiped with elna duorex II ecap. do anybody know this cap?
