[quote:06c0a74f6a="viewer"]thank you so much,

finally changed outup wire.
the result is great.
Thank you for sharing.[/quote]

Hi viewer,
i want to change my CAP too, what is ERO MKP 1852 cap? from what manufacture?

i heard of alot of review said change to silver/ oil or silver cap have more brighter sound but will softer the bass n midbass, so what should i change?
any CAP that can have all even sound?

[quote:669df3d9e2="viewer"]hi superwhite,

The ERO cap is Germany company the quality same to EOR cap and wimma. It is better than wimma for high notes. (clear and smooth) I make this in power filter of MHZS  CD33 only. Sound outup changed Jensen alum Paper oil 0.22uf/630 these cheaper than copper much. then the mid bass is better. (I feel)
I also replaced the 4 rubycon caps before Elna to Nichcion (Muse) 4,700uf/25v Real product not china product (Green with bule cloue words.) buy it in 凱韻 (油麻地) HK$25 each.

Thanks[/quote]

Hi Viewer,

Hi DUALXEON,

I totally agree with you, but there are some good seller in website......
I brough some WESTERN ELECTIRC 396A from ebay also......bcoz cheap.
:roll:  :roll:  :roll:

Hi to all CD33 owner,

I want to share something to you, i have change my power coupling cap to Mundorf ZN cap, n also the tube coupling cap to Mundorf Silver/oil. Pure silver cable 0.33mm from PCB to RCA. Ofcause the most important is change the tube, my is ERICSSON 396A.
I had try on WE396A also, but still prefer ERICSSON, because the VOCAL sound more TRUTH, not to said WE bad, it just that WE is too musical(is all depend on individual taste)

Now the Sound totally change, more clear, detail n fast,
Will change the OPAMP to 627 if the stock arrived, hope can give me another surprise! :wink:

[quote:0998739db0="DUALXEON"]Bring you CD to http://vocativeaudio.com/ Mr Chan will give you some more idea Mod and Listen/compare OP AMP[/quote]

Many many thanks for DUALXEON advice on modification, unfortunated i cant come over to  http://vocativeaudio.com/. i'm actually from Malaysia......... :  :  :  :wink: Sorry.

[quote:5fe9148fe2="viewer"]I have upgrade my mhzs cd33 as follow photos.[/quote]

Great! any photo?

will try 1 more thing, BENDIX 6385 TUBE, received many good review on this tube, hope i'm not dissapointed with this tube. :wink:

At first i want to change my Tube Coupling CAP to AudioNote Copper oil 0.22uf, i know this cap really sound good, but have 1 problem, cap spoilt, according to my diy shop here. so i choose Mundorf silver/oil.

Hi,

i need to verify my last post on the ERICSSON tube VS Western Electric tube.
at first i try my WE, sound sweet, easy to accept that kind of MUSIC. the Vocal part is like 3D n also some of intrument too.
After change to ERICSSON thing change, vacal more to natural, intrument part more clear, but 1 disadvantage, noisy compare to WE when increase the volume. Now i going back to WE because the sound more easy to accept(TUBE FEEL). if anyone got budget buy 1 pair of WE396A n try it, let me know the result too. thank for sharing

My WE396A left is 1952 , right is 1949 secondhand tube

Great modification!

can i know what is marked with red ink? what value? thanks!

Hi WINDWSS,

Great to have friend from Malaysia. i'm from KL, work in PJ. i also new in DIY. In Malaysia only have 2 DIY shop :cry: , the most stock is OCTAVE PJ, another 1 is DIYPARADISE Kuchai lama(part time). not much choose here, the shop that is selling GE5670 is DIYparadise RM45/pc. but i prefer WE396A(my opinion). you want to put GE5670 to your CD player? what CD player you are using?

i did't compare the GE5670 with WE396A, but if you have we can try it out :wink: . different tube have different sound characteristic, is up to individual to discover it, hope can share MUSIC with you.

Great!   Thanks, Bro! :wink:

Hi VIEWER,

Do you know any sound different on this cap if change to other? is this cap function to supply voltage to the tube? or other function?

Thanks!

[quote:0615b2cd22="viewer"]Hi superwhite,

This cap is supply power for tubes, so very import for sound quality.

When i changed it from M-cap, the sound become detail, smooth and powerful and very balance, win too much.  M-cap's sound just clear only. I also found that have  broken at the bottom of M-caps and other solen caps also. Because they to close  the pcb broad, it were burn by the solder with  the worker.

So i remind all MHZS's cdp owner of this.

Thank you fro sharing.[/quote]

Hi Viewer,

Thanks for your info. look like we got the right choice. :wink:

[quote:43f35aed7c="viewer"]Hi winwss,

The two caps in front of the tubes as a filter of opa 2604's outup, so affect of the sound two much.

both are important, if change boths, that the sound will be closed to prefect.

Have you upgraded you cdp also?

thank you for sharing.[/quote]

Hi Viewer,
i totally agree with you :wink: , WINDWSS, if want to change choose the best or the sound that you like, if not you will waste your money :cry: , think twice before change  :wink:

Thanks Viewer.  

But my transformer has BLOW! :cry:  :cry:  :cry:  HELP! i need help!, where can i found same Transformer? :cry:  :cry:  :cry:

i tot is transformer problem, but after checking found is my power side CAP Shorting(one of the mundorf ZN cap) Dont know why it get shorting. hope is only CAP problem....... :wink:   is this because i using 0.22uf 630V not the 0.22uf 1000V, will it get better?

[quote:fcc7257f13="viewer"]hi superwhite,

Is it really cap solder shorting?????
Is it fine, when you re-solder the m-cap? if just this problem, i think you solder the m-cap not good before.

0.22uf/1000v not better than 0.22uf/630v. becuase the voltage just 220v. I said in hk. I don't know what voltage of your country.

Thanks for sharing.[/quote]

Hi Viewer,

Thanks for sharing, now is confirm cap shorting, bcoz i using my multimeter to measure, i get 0ohm, mean shorting, than i try to measur the second cap, i get infinity reading.... actually i'm electronic background, i get my first soldering tool from my uncle when i was 12yrs old,  :wink: voltage over here same, 220V-240V, normally here we get 240V. will try to ask my diy shop for help, dont know what he can offer me....   :wink:
hope just cap problem....... :wink:

Hi to all,

Finally my CDP is back         

According to my diy shop here, he said the Mundorf ZN is not suitable for power supply filtering circuit, it only use for output side or low voltage circuit. :wink: lucky-ly is only the cap, so i have no choice change the cap to Mundorf silver/oil,( cant get any other low price cap to replace like ROE).
Damn EXPANSIVE leh.

Hi WINDWSS,

She's back.   
maybe can give you some tip on you Bada HD21 modification..... hope to hear you ready for modification...... :wink:

[quote:01733d9729="WINDWSS"]superwhite,

so what's the uF of your mundof/Zn? it is 2.2 or 0.22uF? what will u do with it?? exchange back from the diy shop??
it it suit for the filter at opamp?? (near the tube side).
I had obtain my GE JAN 5670W last night, even only warm up for <1hr, It's sound is so sweet n warm. Resolution, detail & bass tightness may not as good as WE396 but i like it's warm vocal....really comfortable.... i'm quite satisfy at this moment. So wait until u become master of modification then i only start mod hahaha... :  :  :twisted: Temporary just change tube, twist wire enough :roll:[/quote]

same, 0.22uf 1200V , buy new one..... bcoz the shop said this cap cant be use in direct power(mean 240VAC)mean in the power filterring side, not bcoz cant use, but when you turn on the power switch, there is a SURGE current, maybe this will cost the cap SPOILT. :cry:

i tot you buy from web, TUNGSOL 5670?
now you can enjoy the music more...........after change the tube. :wink:

[quote:d93d488c56="viewer"]Hi  WINDWSS,

Total cost for jensen cap around $700 because has discount in hong kong shop.
I used MF A400A class A amp.  and Mission bookself speaker (add DC current on cross caps.).
Total costs of upgrade around HK$1000 but the sound is better HK$10,000.00's cdp.

Diy not base on money. just fun. That is the interestof Diy.

Wah Bro viewer, want meh? use big amp to drive small speaker, the volume not even 8o'clock :  (joke)

Hi viewer,

Need your help, if the cap is 22uf 35V, can i replace with 22uf 50V? any advantage n disadvantage?

[quote:ebaf036558="viewer"]hi, superwhite,
sorry i am late to reply you, because out for dinner.

50v replace 25v is ok it will be better than 25v.
advantage can accept votage up to 50V and lower lost on singal.
disadvantage is the sound speed will be lower.
audionote caps is same as jensen cap, because jensen is oem for audionote.
but the price is lower than audionote.

You said replace siliver cableand inter connect, I think in you cpd will to fast, the sound will be to clear. This is my mind. copper is better.

Thank you for sharing.[/quote]


Hi Viewer,

Thanks for your info, it really help :wink:

not the interconnect, but speaker cable, i found it not suitable for my ear, too sharp, ofcause this cable have more DETAIL n CLEAR compare to my previous cable, is it need to run for long period? will try to get the 7N UPOCC cable n  try it :wink:

but 1 thing, i scare if i change to Copper oil, the speed will become slow....     what do you think?

[quote:0d933f9af1="viewer"]hi superwhite,

In my point, if you change copper oil the speed will slow a little, but very match you cdp 33 Map cap outup supreme siliver oil (speed and clear)
copper oil will add a warm and more bass. It must be run 300 hours.

Thank you for sharing.[/quote]

Hi viewer,

Thanks! :wink:  may try on copper oil n see what different...... but have to run again....... somemore 300hrs

Hi WINDWSS,

see how first, the Cap have been reserve.


Still want to find some solution on my SPEAKER CABLE   dont know what good for my speaker) i still prefer the CABLE TALK 4 , more sweet but less detail........ any good Speaker cable in the market?

[quote:5e48b8d9ea="WINDWSS"]Dear viewer & superwhite,
