SUPERWHITE,

Why don't u open a new title "Modify audiolab 8000S/A" in this forum?
put your photo in then thos who use audio lab can share lah...

this cd33 forum very long till 19 page already!

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,
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,

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

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“

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....

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.

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,

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.

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)?

[quote:635b0e75a3="superwhite"]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[/quote]

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!

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:

[quote:4392fd0bee="viewer"]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.[/quote]

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 windwss,

I think High notes will have great improvement.

please let me know the result.


Thanks.

i goto Octave justnow...
wow their 47u/160v BG VK sell at sky price lah...... crazy...
most probably tomolo will go farnell if got time...


viewer,
do u think i parallel a ERO 0.1uF/0.02uF to the rubycon 47uF/160v ecap got any efect not?

Hi WINDWSS,


:twisted:  :twisted:  :twisted:  The evil is back, be prepare :  :  :

Viewer,

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


Superwhite ,

u don't poisson me lah!!! if not i will ask my wife to kill u!  :twisted:  :twisted:

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......... :  :  :

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 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:

viewer,

Since u had use ERO MKP1845 & WIMA MKP-10, which 1 is better?

MKP 1845 better right? thinking of changing the WIMA MKP-10 (1000VDC,600VAC, 0.1uF) near power filter....

[quote:bb011d349b="superwhite"]Hi WINDWSS,

Hi bro, how is the result of BG? any improvement?? hope you dont poison by this tiny stuff..... :  :  :[/quote]

I almost 毒发身亡!
It have tremendous improvement on my Audiolab (just replace 3 BG standard at the power side).

But for CDP, even i use 2 BG Nseries, got improvement but not that much compare to the rate of improvement of audiolab..... But at least it neutralize a bit my rubycon zl , sound not as sharp as previousely...

So planning to rplace all the cap at power side of cdp with BG step by setp...since BG damn expensive....

Hi WINDWSS,

Hi bro, how is the result of BG? any improvement?? hope you dont poison by this tiny stuff..... :  :  :

Hi WINDWSS,

i really dont know at all, but should be o.k, bcoz my is 100V 160V, mean it have more power(more continues current) i said maybe only. :wink:

Thanks for sharing.

viewer & superwhite,

Another question, can i change the 47uF/160v ecap at power side to 100uF/150v? (in cd33 yours is 100uF/160v-supply power for 2 tube)

i had measure the voltage it is 115v so 150v is ok, but i'm not sure 100uF will spoilt the player not?? since original is 47uF.
Because i wish to change to BG stnd 100uF/150v.

Hi WINDWSS,

From the PIC you post, we really cant know what is which one, but for sure change all will be better sound, Thanks bro. :wink:

ok...

another question:

refer to the picture, this 4 small cap is same value: 100uF/16V.
May i know which cap is couple witch which cap? i'm thinking to chnage 2 with elna (got 2 elna 100uf/50v) and 2 with ZL(100uF/100v).

is it A pair with B, and C pair with D??

hi WINDWSS,

woi!!!! how can change to philip, if like that every one change to philip, then sony will POK KAI loh! :  :  :  :

Hi windwss,

must not can to philip leaser head.
because full set of leaser machine is sony and the control curcits is for sony.

Thanks.

VIEWER,

U r right, my laser head is KSS 213C.

I thought we can change it to a better brand like philips : (

Hi windwss,

If you replace the same model no need to adjust normally.

I thick you cdp's leaser head is used Sony KSS 213Q or KSS 213C.
the best for replacement is replaced the same model, which is marked on the white colour botton.
the replacement can be done by ouself right. just unplug the cable, unscrew the laser head & repalce it right.


Thanks.

thanks viewer,

what's the correct volatage to the laser head? if later i replace a new laser haed i will need to adjust it right?

Besides, any good model/brand for the replacement?
the replacement can be done by ouself right? just unplug the cable, unscrew the laser head & repalce it right?

ss

hi windwss,
the white botton an adjust the power of leaser head, you make the power high
so can read all cd la !!!!!!!!!!
don't make high power of leaser light to much, it may burn. be care.
In this condition your leaser head's life will be over coming half year, becare.
I suggect you buy one more leaser head for replacement later.


Thanks.

Hi Viewer & Superwhite,

I manage to fix my CDP problem on read the CD. Yesterday, i try to adjust the white button at the laser lense(can be turn clockwise or anti-clockwise) then it can read all the CD again.... i guess maybe after i change some ecap and it caus ethe voltage to the laser lense change so need to adjust teh white button for fine tune. then i do an experiment where i change some e-cap again n the same problem happen then i adjust the white button then it ok again.

May i know what exactly teh function of the white button at the back of the laser lens?

Hi viewer,

Thanks for advice, it only DIY shop said, this i have to think twice bfore can process. any one have try out to add 1 power supply for the clock? :wink:

Hi superwhite,
change all the cap to BG n square light blue colour value 100nf, change to 0.1uf 50V BG NX-HIQ. will get better result.
Answer is right but high costs. I think replace the resistors is better than change caps.

Individual circuit for clock is better than only change clock but not much different.
I also use individual circuit for clock in my DAC photo photo before bule colour pcb. but the cost is high. Th votalge for clock around 5v is ok. if for individual circuit for clock between 10v and 12v.


Thanks for sharing.

Hi viewer,

i get some advice from DIY Shop to Mod the DAC part, that is change all the cap to BG n square light blue colour value 100nf, change to 0.1uf 50V BG NX-HIQ. will get better result, but just that have to wait for next year budget. :

also i have ask the shop about the clock, he said not much changes on sound, the best is change to clock with individual circuit n power supply, or just add 1 power supply for our clock will give better improvement. Bcoz clock need the EXTREME CLEAN SOURCES(power supply. But first need to know the voltage for the clock, any idea of the voltage?

Thanks for sharing. :wink:

Hi viewer,

Update on the WINDWSS player, the LCD screen is back to normal, check found is bcoz of the one of the FUSE is blow, so replace it, the only problem know is reading cd..... hope can help him solve the problem. :roll:

Thanks for sharing.

hi Superwhite,

good news,
would you mind to post your prsent cdp for sharig.

Thanks.

Hi

just order some cap ECA panasonic series, is a audio grade cap, i think is better then panasonic FC series. any 1 know about this?

Hi viewer,

Thanks for the voltage info, so that i can confirm is the RELAY die.... , i took back my cdp n check, confirm is the relay die, so replace 1pc used relay for temporary, i already order the NEC relay, n also i have change the plate voltage cap to BG FK series, previous is cerafine(100uf 100V) n also the tube coupling cap Mundorf silver oil to AN copper in oil, nice result more to MID n not so high note......  

the BG FK is BIG............(from left FK, cerafine , original rubycon, all 100uf 100V)


the AUDIO NOTE CAP :wink:


more pic to come......
Especially thanks to my master viewer for help..... :wink:  ARIGATO!



Hi WINDWSS,

want meh, how about your cdp, you dont want to repair it before your built speaker???? :wink:

Thanks for sharing....

superwhite,

your 1 is relay die only....
my1 most probably the laser head die : (

thinking to DIY a proAc response 1sc, now do research on cabinet construction.....

Hi viewer,

Thanks, maybe will get back the cdp today, bcoz there are not started to repair my cdp, so want to try change the relay see any different...... :wink:

Hi superwhite,

Japan brand is better e.g NEC.
Hope you cd will be re-covered early.

Thanks

Hi viewer,

Thanks, the cable actually is connected to ground, it just that when press the play button the relay wouldn't trigger, so it maybe the relay is DIE already, have to buy 1 unit to replace, but dont know which is good for the player. :roll:

Hi superwhite,

If take out the ground cable it will not have sound.
I test before because un-complete curists.


Thanks.
