Yup, needed some flux for better penetration. ;)

Put it in a panavise, hit the little step (to the right of the threads in the picture) with flux, tin it , tin the wire, hit it with the flux again and solder on the wire.

I think a laser engraver may be a better way to tackle that. Google spit out a few interesting hits when I searched for south Florida laser engraving.

You would prolly have better luck at a trophy shop.   Could go the DIY case badge route with it. (print the image on photo paper, cut out, cover with epoxy, finish edges, stick on with double sided tape)

  No. Is a panel mount jack going to fit in there? For example Mouser # 490-SJ5-43502PM

  Absolutely. But in a twisted sense. I don't care if somebody said some boutique parts are not going to help performance.... I'm doing it anyways.

Has anybody noticed the new boards from AMB Labs?   http://www.amb.org/audio/sigma78_sigma79/     Cool stuff. :)      

So umm, something along the lines of the Butte?    http://www.pmillett.com/butte.htm   Boards can be found on eBay...   http://www.ebay.com/itm/161919004080   Enclosures as well.

Pop it apart and re-solder the leads on the headphone jack.  

Fix the grounding. Detailed troubleshooting without a schematic and photos is nearly impossible and typically = a headache for the readers.

Charge pump?   Example: http://www.linear.com/product/LTC1751

Here is one way to do it.  

Falling off loose or can shove it over loose? Either way will straighten it out. Shoot me a message and I will let you know where to send it.

Depends if the mains transformer primary windings can can be re-wired or not.

Killed it by connecting it to a 9 volt battery without a current limiting resistor. ;)

The lead on the flat side (of the LED) connects to ground. Probe it, got voltage across the leads chances are it's backward.

Yes you can check the current draw by measuring amps across the switch terminals.   And yes again.....Measure the DC offset between the right or left output and ground. (both tests are performed without the headphones plugged in and no music playing)   Also check that the op-amp is not...

Try some actual troubleshooting instead of guessing.   . What's the idle current draw? What's the reading when measuring voltage between the op-amp's pin 4 and ground? What's the reading when measuring voltage between the op-amp's pin 8 and ground? What's the reading when measuring between...

Do they have the MCM 21-4590 boards at Farnell?   http://www.newark.com/mcm/21-4590/small-pc-prototype-board-number/dp/38C9100

There you go!

Anybody have the link for that CMoy amp that was built PTP style on buss bars and cast into a cube?

Acrylic starts to melt at around 230° (give or take depending on the trade name). Good luck with that.

Moving the ground from the computer thru the skinny interface cable is the primary advantage an external PSU offers. (especially given the rated noise performance of the local regulators on the waveIO) I would rather not have the line filters but if you keep the umbilical short the simple PSU...

  No, in hardware mode pin 22 is different. And that difference affects the frequency response. Pin 22, internal power reset pin on the wm8740 and is normally left floating Pin 22, internal over sampling rate control on the WM8741.  There are 3 configuration options. 0- (low rate) for...
