Not sure why...but just to see whats inside this cheap thing.
Well - easier said than done...
Im not sure I've ever seen anything put together this well...
Im not sure I can actually get it apart...!
It's totally soldered shut...and when I got as far as pic - the board is soldered to the case - like 2 inches of seam - all solder...
I used some solder absorbing braid - that worked well...Incredible they used so much solder in this thing...
Should I go any further?
-
Ok cracked it open...
-
The chip is Toshiba

Doesn't look so hot...
-
no, it doesn't but I always like seeing stuff opened up ;D +t
-
Thanks for showing us the insides, its a shame that this thing isn't better a/d quality with the type of construction and size, it could make a nice a/d. Is it possible to switch out the toshiba chip for something more suited to our needs? I don't know much about that just throwing out the idea.

That is a great idea, if you could stick a brown burr A/D chip in there it would be a dramatic improvement in quality.
+T for taking stuff apart
-
Hold tight - Im gonna hafta break out the jewlers scope - they eyes can do that anymore...!!!
-
is it an a/d converter or a digital signal converter like going coax>optical

a/d, rat shack carries both

nice, +T sanjay, i had no clue they actually sold an a/d converter ;)

stumbled across it one day on sale for 9.99, lost it in the move over here though so I never had a chance to try it out.

How's this...
-
Is all of that shielding to protect from RF noise?

What specs do you see that aren't so hot?

I think - it also has a video in and will output a S-Video signal...I assumed there would be some shielding due to the video - but not that much...

Thanks for the detailed information on the parts used, their location as well as color!
Shielding has to be complete to be effective. If you look inside an old TV or VCR you see the same thing: only very small holes are allowed in the RF stages. Modern PCs as well: the enclosing shell is conductive and only small holes are allowed in the shell. This prevents RF from leaking out.

Would this thing be better than the A/D in the JB3?
-
No...
-
Would a Burr Brown chip fit in this thing? Would it even make a difference?

I just stumbled across this thread. I actually took one of these apart almost 2 years ago. If memory serves the two main chips are an ADC and a S/PDIF driver. I had the opportunity to listen to this through a high-end audio system, and I can confirm it is utter rubbish (or at least, it sounded trash through the system we had hooked up). In this case, you definately get what you pay for.
