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.

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. rclxms.gif

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.

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 ...

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.

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

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.

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.

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