Hi All,
Question: if i know for sure that I am going to connect a dyimoded ipod to an amp that has dc blocking caps right at the input (eg ra1, pimeta), do I still need to add a caps dock (ipod 5,5) or similar or can I just connect it straight (with a big warning sticker).

Thanks!
Erez

katzer:

Connect it straight to the AC-coupled amp. Then again, it depends on how clear the warning on the sticker is.

- Contrary to what it says on aaronylee's website (http://ayl.nuwen.net/index.php/proje...ipod/page-one/), this mod will allow you to use your headphones through the headphone jack.

As long as YOU know what you're doing, YOU should be OK.

If you ever part with it (sell gift etc), you should let the new owner know about the issue and perhaps include a LOD with caps inside.

I've opened up my Nano 1G and removed 3 of the screws holding the logic board down, but the last one is stripped. Anyone have a way to remove the last one?

Exert a little upward pressure on the board while unscrewing.

I had the same problems opening the nano and taking off the board! I just ended up applying a lot of downward pressure on the stripped area to force the screw to turn.

Is the head stripped, or is it the threads?

The head is the part that is stripped.

You may be able to grab the screw head from the side using needle nose pliers. Be very careful.

I haven't opened a Nano, but I'm guessing it's a small screw. Try using the point of an x-acto knife. If the screw striped, the metal must be fairly soft. The knife blade should be able to cut into the screw a little and let you twist it out. If the knife's blade is too pointy, break the tip off with some pliers.

On second thought, it may not be too late to use a screwdriver with the correct size head. The screwdrivers most people have are too big for teensy little screws.

I have built a dock for my imod (yes, I was too scared to DIY, so paid) using soniqs sax cap's (630v 2.2uf) and after about 40 hours male vocals still sound very quiet, just like when new. The bass is also kind of muffled, but I was expecting some burn in, as with the black gates in my cable. Mids and trebble are nice and tight though, near perfect IMO and female vocals sound fine.

Does this sound like something that will fix itself over time or did I buy fake caps? The only reason I ask is the caps I received are slightly smaller than the size in the datasheet, and the seller (ebay) said this was because they were old stock... I'll leave it running for another 10 hours now, in the hope they will improve, but if this is unusal I shall be looking to replace the caps ASAP.


Thanks in advance for any thoughts on this

Sounds like you need to do some cap-rolling, but even then, Capacitors aren't the be-all, end-all when it comes to tweaking the sound. What kind of amp are you using? I think it'd be better to tweak the amp than putting all your hopes in the capacitor, if you have a tweakable amp, that is. I'm no expert on eBay practices, but it sounds like this guy could be yanking your chain. Try getting your caps from a more reliable source.

Thanks joneeboi - you indirectly solved the problem. I was just using my hi-fi as the amp (nothing special but it works!), comparing between 2 inputs. You suggesting the amp was bad made me plug my dock into my portable amp and it sounded terrible! Turns out that somehow one ground wire in the dock had snapped. So now I have 1 cap with 40+ hours on it, and another with none... I wont start complaining about the ebay seller yet!

On a side note what is cap rolling?


Thanks again,

Suicidal_Orange
