DIP8 to SO8 Adapter (p/n 031101B)

yes. the op amps are in the analog circuit.

1) i'm not sure how the circuit in the x-fi is, but on my audigy 2, when the front opamp was removed, there was still sound, just very faint. it had not been amplified, though the fact that sound is present means the circuit was still complete somehow. on the x-fi, removing the opamp may leave...

could be multiple things. it could be the transformer, but since the humming is intermittent i would bet against it. my bet is that the humming isn't even coming from the amp, rather something around it or the mains circuit it's on. do you have any magnetic or wireless devices in close...

1) capacitors and resistors are pretty hardy in regards to soldering. the sensitive components are usually ICs and/or transistors. 2) to measure DC offset, turn on your source and amp, let them warm up, and play sound/music through them. set your multimeter to DC and put the positive on the...

Quote: Originally Posted by wfarid thanks random! Now if I changed that power cap, should I then change the Vreg as well? if you feel so inclined, yes, but they're both in the digital part of the circuit and changing them will have little to no effect on the sound. that is...

Quote: Originally Posted by wfarid I have the PCI-E Fatal1ty Titanium Soundcard and i can't find the power cap. I'm assuming that I can just switch out all the op-amps with the lm4652s without problems. I attached a picture. never assume anything, young padawan. to be sure, give...

Quote: Originally Posted by RallyMaster I just A/B'd the opamp change with my friend's modded LM4652 X-Fi XtremeMusic (no other mods) and my bone-stock XtremeMusic. I am seriously not hearing a difference and neither is he. Maybe I need some higher priced cans or some high end speakers...
