Firstly, I must say that I'm surprised that this browser, while getting a zero on acid3, could just as easily as my desktop, log on to these forums, and add a new thread. This on-screen keyboard feels quite comfortable, so oodles of kudos and congrats for the neat and satisfying portable web...

So I should delete either the left or the right channel, and then simulate the signal path somehow? I don't really know how I'm supposed to simulate.. And what do you mean by dual supply? +/-... resistor divided?

So I've been working on OrCAD with no prior knowledge of the software, and I've ended up with this: ping in comparison to this: ping (Ahh! Don't laugh!) I don't know how exactly I'm supposed to get something like that into PSPICE and ensure it's functionality, but I haven't...

Silver shielding... More pictures perhaps?

Actually, it's a portable design... and a surprise for everyone on head-fi... Mosfets' and bjts' are probably a bit unnecessary, yet I wouldn't be to sure, as I'm no electrician. I'll keep looking at SPICE ( neat little discovery for myself, thank you ) and decide whether or not at...

Ahhh, I've never used SPICE before. Would there be any difficulty for me to use a simulation program? Also, here's the diagram. Don't laugh. :]

Person? I didn't find anyone by the name of spice on head-fi... I did find SPICE the simulation software, though. Would that be it?

So after the long wait, I am finally able to buy the several hundred dollars worth of electronics to make my own high quality amplifier, however, I want to make sure that this design would work beforehand. I know this may seem a tad unnecessary, but, would anyone mind taking a look at my...

It sounds very much like a hard drive problem, which is usually caused by reckless handling of the internal components of the ipod, particularly the hard drive. My ipod mini also sad faced ( was actually expecting for it to happen ), so I replaced the microdrive with a compactflash card...

Maybe you should try to get a solder with a silver/copper compund. Or if you're feeling lucky, this. Careful. It melts at 290 celsius.

The buffer-based ground looks extremely promising, and it's even recommended to replace the resistor divider with a TLE2426 if expecting to draw uneven loads! If this is what I decide to use, what should I look for in a buffer? Tangent mentions the BUF634's output current and quiescent...

Well, just to be sure, is this parallel or series? Begin simple diagram! . . . . . Well nevermind the diagram. I searched and now know that what I proposed was in fact parallel. Yet since the series functions just as I planned, now I only need to change a bit of wiring within my...

So I have four lithium polymer batteries in parallel to have a 14.8 V output. This is going to power three opamps and two buffers totaling a large 50mA total quiescent ( or 70mA in high bandwidth mode ). My question is how do I supply that current with TLE2426's, and if impossible, what...

So I'm planning my design for a cmoy, and I don't know what specifications to look out for to better suit audiophile quality. I have very little experience with these sorts of things On TI's webste, there is a lengthy selection of opamps, and I've assumed a few of them to be high quality...
