Got my opamps today, just wondering if it's possible to desolder the opamps without any other tools but the iron itself

It is possible. I simply bent a needle and pushed it underneath the pins of the oamps. Then I placed a little more solder on the pins and they wrapped of, nearly, by themselves....

guys if you want more bass,rich and with even more extention,you can try blackgate nx,elna silmic 2 for decoupling.

Do you mean as replacements for the coupling caps?

ya i i tried them and they refused to ship to Egypt

terrorist! did you try with analog devices aswell? As others have mentioned some 3rd party retailers do carry the chip aswell, even though often a bit overpriced. Numerous sources for both capacitors and opamps have been mentioned throughout this thread. All it needs now is a little effort to find places that ship to your country of residence for a reasonable price.
I'm curious why National won't ship opamp samples to your country though.. But if they won't do it theres always Analog and Texas Instruments to try who both make great opamps aswell

I can't wait to hear mine today, got someone to do the mod for me since he's very high skilled in soldering and I don't want to screw mine up. Gotta wait until the evening to get it back

The AD8599 is a great audio opamp just like the LM4562, I have tried them both and like the AD8599 atleast as much.

Just make sure you burn them in. the nonpolars can flip polarity as they burn in, becoming unstable.

I just got my X-Fi back. The new opamps are incredible, so much better than the original opamps in every way and heck it hasn't even burned in yet

Do changing the opamp for the subwoofer make a big difference?

 

[Evisu]

anyone know which are the power supply Caps for the front channel opamp?

 

[MrDerrick]

Hi guys, new here.

Just tried doing the mod and came with a big problem.

Whilst removing the old opamp the 3rd copper rail came off with it!

Can I bridge a wire from the 3rd leg to the back of the board or somewhere else? I tried tracing the track on the back but couldn't find it.
Other then that great sound improvement, but no left channel

 

[ironeisnna]

Heh yours is nothing... I tried to do the mod for the opamp and SIX out of eight coper rails came off. I destroyed my card. Just an advice to anyone that wants to do the mod... The board is so fragile that can be VERY easily destroyed. Just a warning.
