I did not short the caps, but instead replaced them with audio grade caps
Well wtf is national? Like im not up to par on the wording.. i need a little help...

here's a pic of them from a slight angle so you can see



Then I moved on to the power cap. For some reason the negative leg was really in there! the solder just would not melt at all!!! I had to crank my soldering iron up to like 700F just to get it to melt! I'm not sure what the problem was, but it wasn't flux bc I used it... I'm still struggling to get the hole clear so I can get the new Blackgate installed... the rest of the caps went easily enough so I'm not sure what the deal is with this one...
Like I said probably few hundred posts ago, the whole dam x-fi sounds card act as a large heat sink. to heat up the solder on the leg of the capacitor is hard. All the heat you apply onto the card will be transfer to the heat sink and even... the card

Yeah, i realized that the card it self. (touching on the side of the card ) actually heated up when I doing soldering. That made me almost drop my x-fi to the ground

but with the right tool, you should be fine

umm... the company that makes the op-amp... national semiconductor.

had you taken the time to read the first page (you should read the entire thread) you would have known that. There is even a link!

you can email both percyaudio & partsconnexion. I have ordered from both electonically.

yeah, I got it but it was a PITA. I just wasn't expecting there to be that much difference from one side of the card to the other. I was just getting impatient

Strangely enough I had the same problem removing the power cap from my card: one of the legs didn't want to let loose. Even ruined the Jamicon on it's way out. Not a great loss for this world...
Unfortunately the opamp hasn't arrived yet, I'm using the time before it's arrival to burn in the black gate. Using a K701 unamped on the card shows a big improvement in dynamics.

I guess that's what I'll do :\ Don't feel very safe giving CC info via email though.
post #441 of 2194
you can pay via paypal if you would prefer.

I know this works for percyaudio
post #442 of 2194
^ yup, the email and paypal worked for me as well. It was 38 bucks total for both the paper and battery shipped (with the brutal california tax too, naturally :P).

battery? are you battery-powering the X-Fi? that would be a neat idea for a clean power source.
post #444 of 2194
Oops, I meant power filter capacitor, my bad. But yeah, a battery would be an interesting idea.

they are the same...

How was i to know that? so really just 4 x LM4562 (cause i use surround speakers) and one Blackgate 2200uf 16v capacitor and the job is done? Sounds easy. Only thing is for hte samples u have to be part of a company? What I did was use my university email address but used my home mailing address. Hopefully I can still get the opamps. Also if I use a hotmail addres would i still be able to get them? I might not be able to access my university address as I forget hte password
post #448 of 2194
Damn looks like I might have to use a hotmail address. I havent gone on my university email for a long time. Unless.. could I use my work email and still get them sent to my home? I dont even work in the audio industry, but how else would i get samples?
post #449 of 2194
Everyone can request samples, you dont have to be an engineer or student.. They will probably charge you for 's&h' though, 10-20$ depending how many. Max order is 3 in a week.

9.77 for 3. Is that a good deal when some people are getting them for free?
