I need 1 x 35V1000 and 1x 25V2200 black gate !

What is ringing? what which freq u hear ringing at the speaker ? bass, acoustic guitar, vocal or cymbals?

so if the ceramic cap is marked 22p on the casing, is it 22pF or 220pF?

What happen if I put 220pF in place of 22pF for the output noise killing cap of the ZERO DAC .

Ringing is due to the switching action of the diode's depletion zone, i'm not sure where you hear ringing, i've never tried to listen to it before, but i have seen it's effects in really sensitive instrumentation amps.

Changes in capacitance aren't as important as changes in resistance as rule of thumb. If it's for the ground loop breaker, it shouldn't be an issue. If it's for the output filter, use the formula

F (Frequency of cutoff) = 1 / 2 pi R C

Do the math for each (one with 220pF and one with 22pF) and see if the cut off is acceptable. If you ask me the difference between 220pF and 22pF is small in inverse terms (the formula is an inverse, remember that), so i wouldn't worry. But in my opinion, a larger capacitor would mean a lower cutoff point, which will mean less noise, but if you go too low a cutoff point, you lose dynamics and the timbre of the high frequencies.

Hi empy,

I have a problem buying panasonic cap from Farnell, they are stupid to sell something at multiple of 5 (meaning cant buy 6, must be 5, 10, 15).



Can I know the stock main cap 25V2200uF KLE cap is taking in what voltage ? is it taking in at 17V or 15V ? Can I use 16V3300 cap ?
__________________

I think it's 15 volts, that's the usual. But remember when a transformer is unloaded, the voltage can shoot up 50 percent which means 15 + 7.5 = 22.5, meaning 25v is the best voltage rating for the cap.

well u will be poison definitely but on the other hand u will reach to another level of enlightment
lol
dun worry i look after u slowly ler
after we r all here for 1 thing lol rite?
either get poisoned or poison ppl

is no problem ... even my CD63 original just using 470uf 35v Elna Silmic i replace with Panasonic FC 3300uf 35v the bass are more deep and got more energy i found some on the website some mat salleh put 4700uf 35v the voltage better use the higher like empire say those voltage are normally unstable will load very high ... like my fren saw before he got using Voltage Regulator for his main plug to his equipment he saw his meter some time is go up to 260v AC and normal we only 220v-230v even sometime is low

for some reasons, after checking I manage to find Panasonic FC at loose items.

So I am waiting for the Panasonic to arrive tomorow. : )

hehehehe good to hear that u put higher value i remember zero use 2 x 1000uf and 2 x 2200uf

i have 2 x 2200uf 25v

here is my item selection.

to those who want to mod, it is rock and roll.

Chua, so you're buying on your own? Can you post the link here so I can order also? And this is to replace which part? Thanks.

Added on October 30, 2008, 11:09 pmOh, thanks for posting the list. How many pieces do I need for each?

just get from farnell
my cap collection but empire is got alot more hehehe
empire u got any blackgate left hehehe i wanna keep some

Farnell is superfast. order yesterday, today arrive all the way from singapore. They even send in 1 item (worth 10 rm ) all the way from USA without additional costs.

See that little double heart. that is the silver mica. I am going back to putting cap where people snip it.

^that's what i'm telling the farnell skeptics for 10000 years.

Farnell kicks ass, tough there's a learning curve before you know how to make use of it.

EDIT: Eh? You ordered Pana FCs? The FMs are better leh.

Hi little,

I have a project to mod the USB-spdif converter, which I rightly see in your sig.

Can I know what clock u see for the PCM2702E? Is it a separate power source or u use the souce from USB ?

Do u mod the on board cap / XO ?

Do u know where to get XO with 10ppm, cheap and good.

Do you guys have a direct link on farnell to an ALPS volume pot that will fit the ZERO? I got the RK27 model but it doesn't fit :/ The box is too big.

I have a difficulty to remove the capacitor. My first experiment is to replace the 10uF Nichicon muse in the USB->spdif converter to 100uF Panasonic FC.

Tried very hard to remove the cap but it just dont come out, though I had suck out the solder. At the end, the cap is broken.

Hurr, try removing the capacitor by heating one pad and then tilting it to one side, repeat the process for the other side and keep cycling until cap comes out. Works for me.

yeah and dont put ur solder gun too long at the pad will spoil ur pad just heating for 1-2 sec ermm Nichicon MUSE is good enuf y change to FC hehehe

For those beginners trying to DIY the solder job, here is the great guide. Never know tower can stop the wiggling and a magnifier not for old man but a open copper track ...

isnt it fun to see some photos.

he really take pain to insulate the leads !!! also the green sausage dont have polarity right.

it's a miniUSB powered DAC akin to AlienDAC/BantamDAC.

Nah, I didnt mod the on board caps, it's all Panasonic FMs. Probably going to change the output caps to purely film in the future though.

Superior Training Videos.

I think it is better I use solder wick, in order not to spoil the pad.

my CD63 mod now waiting my clock to arrived

Dont worry, the stuff is going to reach very soon Cant wait to see it's impact did on your CD63 ...

I was having a tough time trying to replace the caps. But in the end, it is fun.

I was extra careful, in fact, after each step, i bring it to the amp and test, remove, and back and forth.

haiyaaaaaaa....dont la just post like that bro.....

tell us the result man! how u think of the mod??

are the mods the same as mine?

well , this is only phase 1 mod.

I almost give up, lucky got abel help.

I am more interested into this mod, putting a lot of green sausage underneath the PCB for the power supply bypass.

Added on November 6, 2008, 12:17 amHi Empy,

I would hope u can explain about the pink arrow (missing components or underneath ?) and red arrow (replace resisor with cap ? why )

what is the purpose replace tantalum at the OPA cap ?



tks.

Hi Chua, if you want, I can share with you to split the shipping since 1 pack has 30 pieces.

OK, I am done. I had a singapore guy bought 10 from me, and 10 for u.

rgds

singapore ... not russian meh hehehe?

Does it sound like Jesus is coming ! Welcome to the green Sausages.

Some really get crazy about that .

The final moment has come for the ZERO mod. Just for simple mod on the past few post, I felt the changes in SQ is very stunning.

I just learned putting higher voltage such as 63V has the effect of more capacitance than the 25V.

Now my Panasonic FC begins to reveal its true color. When I first put in (without the green PIO bypass yet), I was like so so ah. then I just wait curiously for it to unfold. after nearly 5 days, I begin to hear the warm of it and the transparency. The punch and the body begins to throw in.

I am just waiting for the PIO to arrive and I hope to be Penchuum, give me the last green sausage.

Yes. ZERO rocks.

but this green sausage be careful bcoz is quite heavy compare other cap

Today spend some time further mod the ZERO, call it phase 2.

Replace the 330uF at the 15V supply to opamp. 2 x elna silmic 2
2. 2 x pana FC beside the opamp,
3. 1 oscon at the optical input area
4. 1 x 47uf pana fc at the clock area
5. replace the 2 tiny 22pf with Silver mica (5%)

phew. during the mod no light on, same as Abel case.

Check back all the cap mod. found jumper lead lifted off. Total jumper 6 nos. wow, really tough, but really sweet now.

eheheheeh becareful

I took about 1 hour to trouble the 2 problem. Tracing the circuit to where it come from. U need a very bright light, and use the backlight to trace. The problem with open circuit is solved if u can handle the multimeter.

Now I am waiting for final phase : -
1. 8 x green sausage
2. 10 x ultra fast diode UF4007

here is the result. [oh my. the sound is really killing me softly. Madmen, can we have ur unit for a AB man]

i spot got 2 silmic hehehe how the sound now

Sounds good. I hope the sound will be better after 250 hours.

Does anyone know the difference between UF4001 and UF4007. What is the forward voltage and reverse recovery time ? which is better ?

both also ultra fast recovery but spec are different pls double check

wanna do another comparison ah?? caaaaaaaaaaaaannn

but now abit tough as im back to work and workload is MASSIVE

not only the workload is MASSIVE,
the item and the jargon being use is a bit massive for me too..

not knowing too much of them..
i think that's y so few ppl replying recently..

Emmm ... now Abel got the SUN discrete opamp and clock ... must be busy integrating it into his CD63 ... Oh ya ... will get my new DAC within this week Will do a review between ZERO dac and DAC100, stay tuned!

Dont forget to bring the unit for review too.

The mod here is easy to follow provided u read up the thread in head-fi. if still complecated, then u may post here what u are not sure off.

the simple mod on zero really results in good sound output. I am waiting for another 100 hours to get the sound stabilized.

i try both earth n sun .... both also i like but moon i not really like it

earth give me neutral sound ... sun give me more energy sound bass more tight n deeper sound stage more wider and forward

Added on November 15, 2008, 4:50 amermm at last i finish install my clock lucky got eddy to help me .. if not dunno until when only finish


at last my zero is alive take me 1 nite to fix it back
now already change some cap

Still see a lot of blue cap. good to see the revival. ready for FrankenZero.

Nice to see your ZERO is alive! Sorry for not helping u reviving it, so you get it back on track yourself?

yeah .. but after sometime new problem opamp no supply go in

Oh my god. Here comes the Franken ZERO ....

no headphone amp???

yeah he remove it bcoz we dont use for headphone just used for the DAC

recently i made myself a Canare L-4E6S cable with Neutrik NYS352G phono, connects the Zero to Aego to sattelite,
i can hear the improvements, totally another steps of upgrades..
